    Rated 5 out of 5 by from This product helped my hair grow I went to my hairdresser and she found that I had developed three bald spots that were not there at my last visit 6 weeks prior. She put me on this kerastase product. My hair grew back and I have used this product for 1 1/2years. I love this product.

    Rated 5 out of 5 by from Multi-use I use this product on the back of my scalp to tame a frizzy, kinky area of hair that can't be controlled by anything........but this. It leaves my hair silky, shiny and frizz free....even in the rain

    Rated 5 out of 5 by from Magnifique I strongly believe in this product and cannot go a week without using it. I didn't like it the first 2 months I tried it, because it was making my scalp very oily, so I stopped it. Decided to reorder it after 1 month without using it and really love it. I found out that I was using too much serum for my type of hair. I have been using it now for over a year and cannot believe the transformation. My hair had stopped growing for years and now it is growing so much! The results is amazing, I had terrible hair, very dry and damaged from the midway of my neck to mid upper back and now it is almost normal and soft :) Rated it good value only because I find it expensive for the quantity.

    Rated 5 out of 5 by from Will be buying more! I received a sample of this product, not really thinking anything could actually do what it says, so I tried it with some hesitation. Well was I wrong.....the serum feels amazing on your scalp..it feels like when you go the salon and they give you a great head massage. Your hair always feels great after and your scalp seems to have enjoyed it too! I was really surprised how great this works, even after just a few uses my hair feels stronger, which with colored you you need all the strength you can get. Thank you for this little miracle.

    Rated 4 out of 5 by from This product smells great but... I wanted to love this product. I have read so many good reviews! Unfortunately, it makes my scalp sting. Wish this worked for me.

    Rated 4 out of 5 by from Great product, but I seem allergic I was quite enthusiastic about this product, but then the reaction started. Has anyone else found they have an allergy to Inialiste? I'm also allergic to PPD but doubt there's any hair dye in Initialiste.

    Rated 5 out of 5 by from Worth waiting for I've been using this product about three times per week for about six weeks. While I did notice some improvement after a week of using this serum, it was only after a month that I fully appreciated the benefit I was deriving from this product. My hair is becoming stronger, healthier, and shinier than ever. I spend less time styling my hair because it's much more cooperative and requires less fussing and fixing. Most surprising to me is that at the end of the day my hair still looks great. This stuff is pricey, but it delivers.

    Rated 4 out of 5 by from The cumulative effect of the product is wonderful. The first day I used Kerastase I noticed a difference in the texture of my hair. However it was on the fifth consecutive day that my hair was softer and looked 20 years younger!

    Rated 5 out of 5 by from This product is amazing I love this product. It was only the second day and I saw a remarkable difference. My hair looks stronger, healthier, even longer; trust me! when you have men, besides your boyfriend, talking about your hair and giving you compliments about it, then you really know there was a change. I have long brown hair and now thanks to Initialiste it is just shinning and beautiful. 2 colleagues already bought it after seeing my results. It is definitely an investment and a must.
