Resistance - Sérum Extentioniste Scalp & Hair Serum

Id say yes but the con…. it soothes my scalp but the amount of product is a little, wish component was bigger. But nevertheless Smells amazing.

Scent is Wonderful!

I love the scent !!!! Makes my strands strong! I would definitely recommend

Must have on repeat!

It helped with thickness and new hair growth! After trying other products they just never worked as well as this one. I’ve been using it almost every day for a year and my hair completely transformed

Hair repair

Absolutely love this product! My hair grew instantly after using it for a couple of months. I pair it with k18 leave in mask for best results!

Wouldn't purchase again

The application isn't easy, you really have to section your hair to apply from the dropper. I find the smell to be pleasant and it dissipates quickly too (i personally like that as I wasnt looking to scent my hair with this product). The formula itself is easy to work in as it's a nice viscosity. I don't feel like this has done anything to help strengthen my hair at the roots though which was why I purchased it. I've been experiencing a lot more hair fall in the last year and I though a serum right at the roots would help. For the price and the lack of results I won't re purchase.

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.

Saved my hair from being cut off

Kerastase is expensive and it's also a great value, if you want to get your hair healthy, it's basically the ICU for hair. I have used one full bottle of serum (about 2 months) and repurchased because I am seeing new hairs about 2 inches long under thinning long hair! My hair is looking fuller and no longer breaking off at ends - getting a hair trim via split ends has ended, finally. I have tried so many HG claimed products and believed my hair was just dry AF & brittle. This has a great scent and is applied at scalp level and gently massaged in, it's not greasy but if you use too much it can weigh hair down.

It has a clean light and pleasant smell, it’s helped my dandruff and my hair falls out a lot less. Only issue is the suction applicator doesn’t pick up enough product for me. May have gotten a defect top but other than that, I will be buying again!

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

Great for fine or oily hair

I don't usually use conditioner around my roots because I have straight fine hair (but a lot of it) that gets oily and weighed down quickly. While I haven't necessarily seen the intended results of this, namely stronger hair that grows longer, that wasn't really my issue. I love using one pipette of this on my scalp after a shower as I find it does a great job of ensuring that the hair around my roots is smooth, soft, and detangled without getting greasy. I also love the smell of this, very lightweight and fresh without being overly floral or woodsy. Just about to buy my second bottle.

Didn’t do anything for me. Too expensive for no results.

Great serum!

Wonderful product for strengthening the hair. It smells pleasant and does not leave your hair greasy.
