Rated 4 out of 5 by from Smells great I picked this because it was recommended from the hair diagnose tool. I think this conditioner is good. It doesn't weigh my hair down and makes my hair look nice but it doesn't help with hair loss in multiple strands when I use this product.

Rated 4 out of 5 by from Smells great I purchased this a few weeks ago. I switched over from the genesis anti hair fall line because this was suggested when I did the hair diagnosis tool on their webpage. It is supposed to also prevent hair fall as well but I don't think it works as well as the genesis product line, my hair is moderately damaged from when I had bleached my hair 3 years ago and I do have hard water. I also noticed with the previous product it did take almost 2 months to start working so i am hoping that after a few more washes it will start preventing hair falling out as well. They are pricey but the last bottle lasted me 7-8 months( I wash my hair once a week) Other than that I think its a great conditioner, smells nice, makes my hair look great without making it greasy or dry.

Rated 2 out of 5 by from it doesn't work for my hair :( I've been using the mask thw shampoo and the serum. My hair is growing faster no doubt :) But the conditioner doesn't work well for my hair at all. It makes it dry, makes the color fade and the ends are tangled. I'm very disapointed because the mask makes it soooooo soft. Won't be buying it again.

Rated 5 out of 5 by from Good match with Resistance Shampoo I got a 10ml sample of this conditioner with the purchase of Resistance Bain Extentioniste and Serum Extentioniste Scalp & Hair Serum. I lost less hair and I come to this official site to buy this product today.

Rated 1 out of 5 by from No difference I bought the conditioner from the Extentioniste line as I had already purchased the shampoo, mask and scalp serum as I wanted to try the whole package to see if the claims were true and I could grow my hair in 3 months. I don't see any difference in my hair at all. Kerastase products always smell nice but I don't see my hair healthier or longer. I feel like I wasted my money.
