Product Story

Like many female divers, I have thick, curly hair that was always a tangled mess after diving.

As a diver AND a cosmetic chemist, formulating an effective, yet environmentally safe leave-in conditioner was a top priority when I started Stream2Sea. I needed to create a strengthening, non-greasy conditioner that doesn’t weigh down even thin, fine hair – but still holds up to a day of masks and hoods in saltwater.

– Autumn Blum, Founder and CEO, Stream2Sea

  1. Lisa

    An excellent leave in conditioner, even for fine hair & during dry winter heating season .

  2. Alice

    I’m an avid scuba diver with curly hair that normally turns into a frizzy mess in the tropics. This leave in conditioner is awesome–the only thing that stops my hair from taking over the world on a dive trip (other than a hat and a ponytail).

  3. Sally M.

    Used the leave-in conditioner and conditioning shampoo on a recent boat trip. My hair stayed soft and tangle-free. Love it!

  4. Monozu (verified owner)

    Smells great, does it’s job of keeping my hair frizz-free!

  5. Bonnie

    I have thick coarse curly long hair and am blown away by how this product softens and tames my hair after 3 dives a day. Have used much more expensive ‘designer’ products and this beats them all. Am SO HAPPY it is healthy and safe for me and the environment. Will be using this at home and on dive trips from now on.

  6. Heidi E.

    I just learned about this conditioner at OWU in Chicago. I am delighted and so glad I purchased it. I have curly hair and I love the shine and definition of the curls after using it for the first time today.

  7. Jan

    Super nourishing! So rich that I, with fine and short hair, need only a pea-sized amount – but my friend with curly, dry hair uses more and my other friend that swims in a chlorinated pool needs a lot. Play with the amount until you find what’s right for your hair — everyone I know loves it and I’m sure you will, too!

  8. Heather

    I purchased this through Amazon as I was willing to try anything on my hair. The ocean and my hair are mortal enemies as my long, fine hair tangles when in salt water. This product worked so well I couldn’t believe it! Every time I got out of the ocean, my hair wasn’t tangled! I highly recommend this product and will continue to use it in the future.

  9. Christina

    LOVE love love this stuff!! I was given a sample at Tortuga music festival. I have really long straight hair and I use about a quarter sized amount. Smells great and leaves my hair soft and smooth!! I also love that since it’s a leave in conditioner, it cuts down on my shower time and water usage.

  10. Melissa (verified owner)

    My hair has never been softer after using the Leave-In Hair Conditioner. I love the smell, and a little goes a long way, even for us long-haired ladies!

  11. Viktoria

    The combination of reef friendly, great smell and wonderful hair make me come back to this leave in conditioner again and again.

  12. Faye

    Hero product! This leaves my hair really soft and manageable and keeps it free from tangles and the harsh effects of sun and salt water. A little goes a long way. Highly recommended.

  13. Autumn B.

    Thanks so much, Faye!

    This leave in conditioner is literally the BEST EVER! I have curly hair and salt water can be pretty tough on it, but this stuff keeps my hair lovely and soft. I use after diving/water activities while hair is still wet. And also as a leave in conditioner after my shower. I initially bought this just to use for diving, but it has quickly become my everyday conditioner!

  15. Carolyn (verified owner)

    This is the best conditioner I have ever used! I live on the boat 3 months during the summer and have very long thick curly mermaid hair. This product means I can swim every day, get a brush through the mane with no difficulty, let it air dry and go! I love this conditioner and carry samples on the boat to give out to other mermaids I come across!

  16. Melissa (verified owner)

    My hair is fine, but I have a lot and it does have natural wave. I used this for a week at Florida beach and it kept my hair from looking like a rats nest with frizz. I was able to put this in and let my hair go crazy naturally for a week. Loved it and would highly recommend.

  17. Melisa K. (verified owner)

    omg this is amazing!!!!:))) this is the only product that literally saves my hair ! it is sooooo elegant smelling( green tea and ylang ylang!!) It goes on so well and it doesn’t make my hair look oily at all. It also protects my hair from swimming. And also it is super cost effective because a little bit goes a long way! I am addicted and I am super picky with hair care!

  18. Bri (verified owner)

    Smells great and leaves my hair feeling light and soft. Awesome product!

  19. catherinefox

    My hair used to always get super tangled after a dive, but now I put it in before and I never have that issue anymore! My hair is so soft and manageable even with all the salt and wind!!

  20. meganmcl38 (verified owner)

    This is my favorite product!! It is the perfect remedy after salt water and long periods of sun exposure, it took out the tangles and made my hair not feel like straw and it smells SO GOOD! It was also the quickest package i’ve ever received from an online store and I ordered it during the holiday season! Very Impressed.

  21. Rachael (verified owner)

    This is a must buy! My hair has never been smoother or softer after a day in the ocean and wearing a mask. I’ve been hesitant to use products in the past because I’ve been worried about their impact on the reefs, so I’m so happy to have found something that is reef safe AND incredibly effective!

  22. Suthrncat (verified owner)

    I tried this last year on a live aboard, trying to be more reef-friendly. I’ve ordered again to use it at home and just ordered the bulk size. I have curly-frizzy hair and a lot of allergies, and this works great! I’ve actually been able to go from washing my hair every day, to every few days wi5 no build up and no itchies! It leaves my hair soft without weighing it down or making it greasy. Can’t go wrong on this!

  23. Liz (verified owner)

    I purchased this leave in conditioner on vacation and then went back to the website for more!Great for my curly hair and I love that it is great for the environment too

  24. Melissa (verified owner)

    I found this gem in Curacao a few years back and have been buying ever since! It’s literally the only thing that untangles my thin hair after diving (I put it on before and after!).. Silly be I’ve relating it to diving ever since and only recently thought..duh… why can’t I have soft hair all the time with no knots! Now it’s my go to leave in!

  25. Jill B. (verified owner)

    This works so well with the Shampoo and Body Wash. My hair felt so light after using both products even though I’d spent most of the day in the sea.

  26. moochka7 (verified owner)

    Because you are protecting marine life, which is so important to me, as well, I had to try a product of yours. This leave-in conditioner is the best-smelling, smoothest hair product I have ever used. This will be my third and fourth bottles. Thank you!!!!! naomi

  27. Fanny (verified owner)

    This leave-in conditioner is amazingly light but rich and nourishing for my dry curly hair, and doesn’t even strip the goofy bright colors from Manic Panic or Arctic Fox I sometimes like to sport. Really happy with this leave-in conditioner for entertainment, sports activities and life uses.

  28. Undrthesea (verified owner)

    This is hands down THE best conditioner I’ve ever used. I have very long hair (down to my rear) and I’m a diver so you can imagine the beating my hair takes with the sun and salt. I’ve used and tried just about everything out there to keep my hair healthy and manageable and this leave-in is amazing! The best part is that it’s light weight, hydrating and makes my hair so soft. I’ve always had to use a regular rinse out conditioner in addition to a leave-in but not with Stream2Sea Leave-in. It’s wash, towel dry, leave-in condition and GO!

  29. Tabitha L. (verified owner)

    This stuff is literally the greatest thing ever. My hair was so soft after a day in ocean. No tangles at all! Plus I feel better knowing I’m not wearing anything that could hurt our oceans.

  30. Kim L. (verified owner)

    I have long, thick, curly hair that tends to dry out easily and this conditioner works really well for me. I use it as a rinse out, and together with the S2S aloe gel, as a hydrating cream gel. Leaves me with soft, defined curls even in the humidity of a Florida summer. Love that I can go from work to swimming or diving without worrying about damaging the ecosystem 🙂

  31. John C. (verified owner)

    Great conditioner. I use it every day. Fantastic company

  32. Danielle

    Love ALL Stream2Sea products! But this conditioner is one of my favs! It smells great and leaves my hair feeling soft + I don’t feel guilty jumping in the ocean after I use it!

  33. Amber (verified owner)

    Being a FL girl I have been looking for environmentally friendly hair products forever. This was recommended to me by a fellow scuba diver, and I had my doubts. She has thick, curly hair and I have fine, thin hair. Well, I love it! It has become my everyday conditioner, combined with the shampoo/boby wash. Leaves my hair soft and gives it some body.

  34. BluberrySea

    Can I give this 6 Stars? I found it by accident at a dive shop in Florida a few years ago and haven’t used anything else since. Pre-dive, post dive, post pool session, and every day. Keeps my baby fine, curly hair tangle free, soft, and manageable. I use it every time my hair gets wet….

  35. Joy O. (verified owner)

    Originally bought this just to take on scuba trips, but now I use it every day! I love the smell and it always leaves my hair feeling super soft. My hair used to be a matted mess after a full day of diving in the saltwater, but now I use this leave-in conditioner before and after and it works like magic! Super effective and ocean safe!

  36. Jo B. (verified owner)

    This is my favorite after swim or diving product. I keep a tube in my dive bag and after diving, apply it to my shoulder length hair. I am able to pull a comb through my hair without pulling any strands out. I share this with my customers and give them some to try because I want everyone to know how great the product is. Because I share it so often, I buy it in the large size and refill my small tube to carry with me.

  37. kyra (verified owner)

    This is the best leave-in I have used. I have thick long curly hair. This product is smooth and does not leave nasty stiff build up on my hair but smooths the frizz and leaves my hair bouncy not stiff or coated. The most important feature is that I live off grid and care deeply about my watershed and can rest assured this product is made with the integrity of ingrediets that will not disrupt the health of my grey water systems and occasion creek I may jump into!!

  38. greg p. (verified owner)

    Bought this to help support MUCC – and love it. Smells great and leaves my covid-long hair soft and manageable.

  39. Heather S. (verified owner)

    I have long, fine, highlighted hair, and it is A MESS in the ocean. This stuff is great. I run it through my hair before swimming and tie several hair ties in it. It comes out easy to comb through and NOT in a million knots, and I know it is not harming the ocean! I also use it as a detangler after showers. I really like this company.

  40. Heather (verified owner)

    I bought the huge bottle after buying the smaller tube. This stuff is amazing because it keeps my fine, long, highlighted hair from being a ball of knots in the ocean, and it’s not harming the ocean! I now use it daily as a detangler. It smells great – not too strong at all. I really like this company – protecting the ocean, no bad chemicals, and recycled plastics. What’s not to like???

  41. Sarah (verified owner)

    The perfect replacement for my hair styling cream that I normally use.

  42. Andrea L. (verified owner)

    I like the feel and fragrance of this product, and knowing it is reef safe is HUGE! It does a great job of de-tangling and protecting my salt ridden hair on dive trips.

  43. Jeanne

    Left my long, fine hair free of tangles and smelling wonderful, even after using the shampoo and bodywash with saltwater! Works great and environmentally friendly, a win-win!

  44. Summer (verified owner)

    I was skeptical about a leave-in conditioner but this makes my hair feel great. I also love that it cuts down on my shower time.

  45. Courtney J. (verified owner)

    This is my favorite Stream2Sea product. This leave-in conditioner has converted me to a leave-in believer. It saves a lot of water when you don’t need to wash it out, which is important to us all, but especially so when cruising on a sail boat and water is even more limited. It also completely detangles my long hair and leaves it super silky. A very happy surprise. You should not hesitate to try this along with the shampoo/bodywash combo.

  46. Zoe D. (verified owner)

    Keeps my hair smooth after diving all day, better than anything else I’ve tried!

  47. Zoe D. (verified owner)

    I love this reef safe conditioner! It keeps my hair smooth and prevents knots after diving all day. Love love love! Ordering again now.

  48. April

    I have color treated hair and am very careful on what I use to protect it. I was unsure of using the leave-in conditioner but after one use, I was hooked! The smell is soft for even us sensitive ones. My hair never felt so soft and it kept the tangles nearly all out after my next dive. These are the only products in my scuba kit! At the end of my trip, my color still looked great! It didn’t strip it out.

  49. SJ C.

    I have hair down to my waist & the salt water makes it impossible to get through the snarls. After a snorkeling trip the boat captain saw me struggling to comb my hair out & they happened to have a tube of this on board. My comb slipped through the snarls. All I can say is I am converted! This leave in conditioner is amazing.

  50. SJ C.

    I have waist length hair & combing through in a good day is tough but being in the salt water makes it impossible. A boat captain happened to have this on board after a snorkeling trip & offered it to me after watching me struggle. This stuff is amazing! My comb slipped right through & my hair felt hydrated. I’m a convert & buy the largest bottle.

  51. Robin R. (verified owner)

    bought at recommendation of friends, reef safe

  52. Ainsley (verified owner)

    I bought this for a beach trip works amazing and smells amazing. I am now going to purchase more to use around the house on a regular basis for myself and my two long haired girls. Takes out all the tangles and leaves your hair super soft.

  53. Sally M. (verified owner)

    I love Stream2Sea Leave-in Conditioner! It stands alone or can be used after a rinse-out conditioner! It can be used in-between washes to help with tangles! I use this at home and take travel-sized tubes on trips! The packaging is biodegradable, by the way! What a great way to use a great, reasonably priced product and contribute to clean water, double-SCORE!

  54. Angela

    This is the best solution I have found to keep my naturally curly hair from being frizzy. I use it everyday!

  55. Danielle

    I have super fine curly hair that tangles miserably when diving. I got a bottle I’d Leave In Conditioner at Roatan diving last week and it’s Amazing

  56. Nikki

    This product has been recommended to me again and again. I’m usually skeptical to try a new product but with this leave in conditioner I am so excited, I’m purchasing two bottles right away

  57. Nichole

    My friend turned me on to this and I am so happy she did! Totally obsessed. Will buy the big bottle this time.

  58. Kristel

    This is by far my most favorite conditioner to use after diving. It smells good, leaves my hair feeling great and of course it’s environmentally friendly. Highly recommended!

  59. Jocelyn (verified owner)

    Bought a sample size for a sailing trip in the Caribbean and loved it so much I’m buying a regular size to use at home. Smells good enough to eat and leaves my hair much softer than my regular conditioner.

  60. Christina

    I love Stream 2 Sea products. I make sure all of my dive buddies know about the leave-in conditioner, because any diver (with hair) knows that it’s the only tool in your dive bag to help combat all dive hair issues. No more having to cut out hair ties after a dive. All of the products I’ve tried have been great and they smell amazing. The biggest reason I purchase Stream 2 Sea is that it is reef-safe and I want to protect the reefs that I love to view underwater. Try the sting relief to take the sting out of pretty much anything!

  61. Gretchen

    I tried a friends Stream to Sea Leave in condition during a few days of diving and I was hooked. I have lots of blonde highlights over dark hair that get easily tangled after saltwater and chlorinated water. I’m buying my own!! Thank you STS!

  62. Jenn W. (verified owner)

    This is my go to conditioner for when I am diving, I always have a small container with me to get all the knots out. But I love it so much that I’ve purchased the large bottle for everyday use. It makes my hair so incredably soft.

  63. Chris

    I love it. Not heavy or greasy on the hair. My hair drys nice and soft.

  64. Sarah

    I always take this on my trips to the islands for snorkeling – protects my fine colored hair and makes it soft. It works great and safe for the ocean.

  65. Alexis M.

    I’ve tried a ton of leave-in conditioners – all have left my hair greasy or looking extra oily. But with Stream2Sea, If i put it in – I can go almost 3 days without the needs to wash my hair and it continues to keep my hair feeling great! I haven’t used it after swimming yet – but it works miracles for even everyday use. I searched forever for eco-friendly products and this is a sure bet and I tell everyone that at least when I enter the water – I know I am leaving NOTHING behind to harm the wildlife.

  66. Lorraine S. (verified owner)

    Love the leave in conditioner….being in salt water leaves my hair dry and flyaway. Using this after being in the saltwater helps so much to keep my hair from tangling, breaking and drying out. I have recommended your products to many other snorkelers and divers!

    Simple. This is not good …it’s great ..

  73. Debi (verified owner)

    I have short hair and use this every day, whether I am going in the ocean or not.

    I just wish there was a 3 oz size! (Bought an empty bottle and filled it to take with me when travelling, although you don’t really need very much and the travel size would probably work well)

  74. Yuko T. (verified owner)

    I originally started using this leave-in conditioner under my hood when scuba diving to keep my hair from getting too damaged by the ocean, but I’ve since started using it on an everyday basis as well. It works better than all the other (far more expensive) products I’ve tried, and my hair stylist was impressed by how nice my hair was. For context, I have semi-long 1A hair and this keeps my hair soft without being greasy or heavy, and it smells nice to boot. I highly recommend this for diving but I also encourage everyone to give it a shot normally as well!

  75. Kate P. (verified owner)

    So dumb to apply conditioner only to rinse it out. This is so much better. Think of all the water I’m saving!

  76. Brianna (verified owner)

    This has made me able to swim in the ocean and keep my long hair manageable. Wonderful stuff.

  77. Alexa F. (verified owner)

    This is the best leave-in conditioner I have ever used, and I have tried SO MANY! It conditions and detangles perfectly without weighing hair down or making it greasy. I love it so much!

  78. Mindy

    On a recent dive trip a buddy offered me to try their Stream2Sea leave-in-conditioner after overhearing me complain how dry my hair was after 2 days of diving. It worked surprisingly well. I was able to detangle my hair with my fingers before using my brush within minutes. Going to buy some for myself!

  79. Danielle (verified owner)

    First time user of the Conditioner and absolutely love it! Took it with me to Roatan and used it twice a day. Hair has never been so soft.

  80. stephaniekvcs

    I tried a sample of this at Natural Grocers and found it worked great on both mine and my sons hair! I have fine blonde hair, and my son has thick, coarse, brown hair—worked like a charm on both! I plan to purchase the full size online.

    I always avoid getting my hair wet in pools, etc. However, I may reconsider if using this before I jump in to protect it.

  81. Melissa L. (verified owner)

    I first learned about this on a dive trip in Curacao and have been purchasing it ever since! Must have before diving and fresh water seems to activate its capabilities after, I’ve started using it daily not just diving!

  82. Scubag (verified owner)

    I love this conditioner. I don’t need to worry about rinsing it out and has made my hair softer and less tangles.

  83. Kristi H. (verified owner)

    I have long, wavy, blonde hair that tends to tangle into ugly matted knots when I’m in salt water. Not with this conditioner! I apply to damp hair and put it into a tight bun. I always rinse at least the bun with fresh water between dives. At the end of the day, my hair falls out of the bun with no trouble so I can wash and easily comb out. This conditioner leaves my hair feeling soft and looking great!

  84. Shelia (verified owner)

    It is wonderful for my curly hair.

  88. Sam H. (verified owner)

    This conditioner lasts forever since you don’t need a lot. And it makes my hair so soft and erases split ends!

  89. ggause

    I use this everyday! Protects my hair while not weighing down my curls. It is awesome!

  90. Chanin W. (verified owner)

    I have SUPER think, long hair. Usually it takes 20-30 mins in shower combing out after a 2-tank dive. I was amazed (no exaggeration) at how easy the comb through was and that it was like 5mins in the shower after my dives. I LOVE this product.

  91. Chanin W. (verified owner)

    I have really thick, long hair. Combing out my hair after diving was a 20-30 min ordeal in the shower. Using tons of my old conditioner. I read about Stream2Sea on a divers FB group page– and OMG, this stuff is AMAZING. A quick 5 min comb-through. WOW. Just made a big re-order !! LOVE IT.

  92. Key

    My hair looks amazing after a long day in the beach. Its great for frizz control and works for every hair type. Love it

  93. Morgan B.

    I have curly, fine hair, I needed some thing that I could apply in the morning and again after swimming in the ocean that would deal with the frizz. I love this product, it gave my hair beautiful curls without flyaways before and after swimming.

  94. Tammy

    A fellow diver raved about this on the boat. My hair has been breaking and this really works!

  95. ioana p. (verified owner)

    Got this due to recommendations and already used it before – the big size of brilliant for family- love it for my daughter who is autistic and tolerate one lot of water with shampooing but second to rinse a conditioner is hard on her. This leave in conditioner avoids the extra rinsing and leave her beautiful long and curly hair easy to comb and beautifully defined curls. My hair is coloured and I have a sensitive scalp- and this is great for my hair without any itchy ness or irritation – thank you Autumn for brilliant formulation and thank you for complementary products to try

  96. Jacqueline V. (verified owner)

    I bought this conditioner as a last resort. As a diver my hair is destroyed and I needed a solution other than cutting it off. This conditioner is amazing and has changed my hair texture and revived its condition. So much so I use it when ever I wash my hair regardless of diving. Now buying it in the bulk size so I never run out.
    Great customer service as well I know look forward to trying the other products ❤️

  97. Alina

    Hair feels so soft and didn’t break with mask straps

  98. jacqueline v. (verified owner)

    This has changed my hair I use it after every wash not just when I scuba dive ❤️

I bought this for a beach trip works amazing and smells amazing. I am now going to purchase more to use around the house on a regular basis for myself and my two long haired girls. Takes out all the tangles and leaves your hair super soft.

I have waist length hair & combing through in a good day is tough but being in the salt water makes it impossible. A boat captain happened to have this on board after a snorkeling trip & offered it to me after watching me struggle. This stuff is amazing! My comb slipped right through & my hair felt hydrated. I’m a convert & buy the largest bottle.

I have hair down to my waist & the salt water makes it impossible to get through the snarls. After a snorkeling trip the boat captain saw me struggling to comb my hair out & they happened to have a tube of this on board. My comb slipped through the snarls. All I can say is I am converted! This leave in conditioner is amazing.

I have color treated hair and am very careful on what I use to protect it. I was unsure of using the leave-in conditioner but after one use, I was hooked! The smell is soft for even us sensitive ones. My hair never felt so soft and it kept the tangles nearly all out after my next dive. These are the only products in my scuba kit! At the end of my trip, my color still looked great! It didn’t strip it out.

This is my favorite Stream2Sea product. This leave-in conditioner has converted me to a leave-in believer. It saves a lot of water when you don't need to wash it out, which is important to us all, but especially so when cruising on a sail boat and water is even more limited. It also completely detangles my long hair and leaves it super silky. A very happy surprise. You should not hesitate to try this along with the shampoo/bodywash combo.

I was skeptical about a leave-in conditioner but this makes my hair feel great. I also love that it cuts down on my shower time.

I bought the huge bottle after buying the smaller tube. This stuff is amazing because it keeps my fine, long, highlighted hair from being a ball of knots in the ocean, and it's not harming the ocean! I now use it daily as a detangler. It smells great - not too strong at all. I really like this company - protecting the ocean, no bad chemicals, and recycled plastics. What's not to like???

I have long, fine, highlighted hair, and it is A MESS in the ocean. This stuff is great. I run it through my hair before swimming and tie several hair ties in it. It comes out easy to comb through and NOT in a million knots, and I know it is not harming the ocean! I also use it as a detangler after showers. I really like this company.

Safe For You and Safe For Our Waters

What does tested & proven safe means for our bodies, waters and coral reefs?

Just because the front of the bottle might say it is reef safe does not mean that it is. That is because these terms are not yet regulated. You still need to look at the back, starting with the active ingredients listing. We have also discovered that just because a product is safe for people does not mean it’s safe in an aquatic ecosystem. Modern science has given us many lab tests to determine the safety of cosmetics, but there are currently few scientific lab tests to see if products are harmful to fish, coral and other aquatic life. We put Stream2Sea products through numerous studies to prove our safety, and believe that our products are the safest on the market for all your water, reef and outdoor activities.

Biodegradability Tests

It is important to know that just because a product is biodegradable for example, a biodegradable sunscreen, does not mean that it is non-toxic. To be considered ‘readily biodegradable’, the product must break down into its natural state from 60-80% in 28 days. Stream2Sea products are readily biodegradable in fresh and salt water.

Reef and Marine Life Safety Tests

Swimming behavior with Stream2Sea biodegradable mineral sunscreen is relatively unaffected, whereas the competitor sunscreen most definitely altered the fish’s swimming behavior.
