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!!

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.

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.
Rated 5 out of 5
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.

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).
Rated 5 out of 5
An excellent leave in conditioner, even for fine hair & during dry winter heating season .
