Kerastase 229821 Resistance Serum Extenioniste | 50ml is rated 2.5 out of 5 by 6.
Rated 5 out of 5 by from Great product To be honest , I’ve been using many oils to frow my hair but woth no luck . Once i tried this serum my hair started to get longer for 1 inch during 3 -4 weeks. I would recommend to improve the packaging because the drop falls before reaching scalp

Rated 1 out of 5 by from It gave me scapl problems I bought the product 2 months ago and my scalp started itching and having dandruff sadly. I do not recommend this product.

Rated 5 out of 5 by from Fantastic product I have purchased this amazing scalp serum and don’t expect to have such a amazing light and silky hair straight after first use. Smells Devine. Fresh and light
Date published: 2021-04-03
Rated 1 out of 5 by from Unbearable I purchased this product a few weeks ago and tried immediately on dry hair/scalp...it made my scalp itch so bad it was unbearable, so I had to thoroughly wash it out. I thought maybe I would give it a second try while also adding the Nutri Supplement Scalp Serum directly after the Resistance serum, but the same unbearable itch occurred. This is by far the worst hair product I have ever used, and will never purchase anything from this company again.

Rated 2 out of 5 by from What does it suppose to do? My hair-dresser recommended this and I bought it on spot! I haven't noticed a slight change with my hair. The hairdresser said it will help with hair growth and it is amazing in general. But is it? who knows?! Maybe it didn't work for me but it works for everybody!!?
