Rated 5 out of 5 by from Thank you Kerastase!! After losing a huge amount of hair and complaining to my colorist for the past year about the porous condition of my hair, I researched products and found a salon right near my home which uses and sells Kerastase products. I've only used the Therapiste conditioner and shampoo twice and the difference in the texture and strength of my hair is drastically different! I can run my hands through it without fear of it falling out. I followed directions to a t and must say that I love these products. My hair feels silky soft; it's almost as if it was crying out for this stuff! When I come out of the shower, I spray on It's a Miracle 10 leave in conditioner and comb my hair with a wide tooth comb. The hair dresser also recommended I use the thermal heat protectant which I bought. I let my hair naturally dry while putting on makeup and then I take a dime size amount of the protectant and rub it in the palms of my hands and then run it through my hair before drying, especially the ends. Drying is something I just can't give up due to the fact that I work out every morning and sweat. However, I no longer wash/shampoo my hair every other day, instead I just wet it and proceed with the steps mentioned above. I highly recommend these products for anyone whose hair looks like cotton candy!! The day and night change between a trim and these products is miraculous!!

Rated 1 out of 5 by from not great for me I used this, along with BAIN THÉRAPISTE shampoo, as directed, for a couple of weeks and my hair was heavy and weighted down and frizzy, but I kept using it. I noticed my ends were getting worse and breaking more, but thought maybe it was just my hair. I had to then use my old designer shampoo and coniditioner and with juse ONE USE, my hair is so much happier, softer and even the ends are softer and aren't breaking off and just look way better. This was an investment for me and I am sorely dissappointed at the waste of money. I'll continue using my old shampoo and conditioner combo, my hair looks so much better in comparison with how it looked during the two weeks on this overpriced routine.

Rated 3 out of 5 by from Hair feels great but scent is way too strong So I have mixed feelings about this product. I used it for the first time today an my hair is soft and silky but the scent is so strong that I want to run away from myself. It's like I'm wearing perfume today and smell like a field of strong flowers. To the point where I'm not sure I'm going to use this product again. Please tone down the scent.

Rated 5 out of 5 by from OUTSTANDING AND LONG LASTING RESULTS! I use this conditioner along with the Bain Therapiste shampoo. I do not use the conditioner prior to shampooing my hair like the instructions call for. I wash and condition my hair in the traditional way and it works to perfection. When I apply the conditioner, it doesn't make my hair feel super soft or anything special, BUT, once I towel dry my hair and use a comb, that's where I feel the amazing difference! My hair is soft and tangle free... TANGLE FREE! The scent at first was too strong for me but either I got used to it after the first use or the scent has somewhat dissipated since opening the container. It is a beautiful perfume scent. My hair literally looks healthy after using this shampoo/conditioning duo. Once my hair is blow dried, my split ends are not that visible, only a few here and there. My hair is super shiny and it looks healthy. I highly recommend this to anyone with badly damaged hair, like mine. My hair is dry, brittle and full of split ends. I must say that my hair is improved from using this duo and I will continue to do so, for as long as I color, highlight, and use the hot curling iron on my hair.

Rated 5 out of 5 by from Love!! This is really great for fine damaged hair. I was skeptical on how well this would work since it is used before shampooing, but it leaves my hair feeling really soft and healthy looking, even into days 2 and 3 after I wash. It really does help to revitalize damaged ends and does not weigh down my hair at all. If your hair is fine and damaged I would give this a try.

Rated 5 out of 5 by from The VERY best product I have come across! I had a bad bleach experience at a new salon I was trying and came out with very very damaged hair. After many tears (the stylist and I both), I was recommended this product line. I was hesitant to spend that amount of money on shampoo and conditioner, but I soon found out it was SO very worth it. I bought the whole line: shampoo, reverse care conditioner, serum, mask, etc.) Within 2 washes, I could tell a dramatic difference. It's now been 1 month and I am convinced I will never use anything else. My hair is back to the health it was pre-fry and I am a forever Therapiste customer!

Rated 5 out of 5 by from Does exactly what it says it will! I have ultra fine, somewhat aging hair. Upon a recommendation from my hairdresser I got this product along with the shampoo. The idea of using a conditioner first followed by a shampoo made me a bit skeptical as I was concerned about fly-away strands. On the contrary, using this product has made my hair feel soft but bouncy. After using the conditioner/shampoo (in that order) combo, I can run my fingers through my wet hair without being tangled. When I towel dry my hair I already feel the difference to the density of my hair, feeling fuller and bouncier. Hands down this is one of the best products Kerastase has come up with and 100% worth the investment.
