    • Keeps my hair healthy
Best product I have ever used. Smells divine.

    • It works to grow new hair!!
I’ve been very impressed with the Kerastase Resistance Extentioniste Scalp Serum. It has a clean, fresh scent and doesn’t weigh my hair down or make it feel greasy at all. The most noticeable result for me was new hair growth—I started seeing it in just about three weeks. At first, the new growth looked like little broken hairs on the top of my head, but they continued to grow. Now it actually looks like my hair has long layers, which I love. This serum has become a staple in my routine, and I would definitely repurchase. ... show more

    • Kerastase Serum
Wonderful serum to use once a week. Serum is light and has a pleasant scent. I love the Kerastase product line

    • I will buy these again
I've been using this line of kerastase haircare products for 2 years now. My aging hair is soft and silky and the white hair is shiny. I do not color the hair because it's natural color, texture and shine are better than had it been colored.

    • Small botthe
The bottle is so small. Too expensive for the amount of product. I used the bottle, and I haven't seen any improvement in my hair. Other products show results in less than 2-3 weeks.
