    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.
    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!

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

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

    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.

    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!
    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....
    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.
    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!

    Great conditioner. I use it every day. Fantastic company
    Kim Langford
    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 :)

    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.
    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!
    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.
    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

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

    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!
    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.
    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!
    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!
    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.

    Thanks so much, Faye! #ProtectWhatYouLove
    The combination of reef friendly, great smell and wonderful hair make me come back to this leave in conditioner again and again.
    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!
    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.
    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.
    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!

    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.
    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.
    Smells great, does it's job of keeping my hair frizz-free!
    Sally Mohr
    Used the leave-in conditioner and conditioning shampoo on a recent boat trip. My hair stayed soft and tangle-free. Love it!
    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).
    An excellent leave in conditioner, even for fine hair & during dry winter heating season .
