Siero Resistance Extentioniste – Siero Per Capelli Più Lunghi

Using for 6-7 years - totally transformed my hair.

The only downside of this product is that it’s increased in price over the years, but of course, I’m still gonna buy it. I couldn’t grow my hair past my shoulders for years. Out of all the products I’ve tried (some left, some kept), this is the product that’s done the most for my hair. I wish I could afford to buy all Kerastase products!

Amazing product

Finished a whole bottle of this product and just ordered my second. Takes a few weeks of consistent use to notice a difference, but it has definitely made my hair way thicker and stronger. Will be buying this product again!

Hair feels great and healthier

I like using this in combo with the genesis serum. I feel like the two products work so lovely together, strengthening existing hair while also allowing for new growth. Love the way it feels and will continue to use

Stronger, Healthier Hair

I love the Kérastase Resistance line. It’s made my hair feel stronger, smoother, and much healthier with noticeably less breakage. A little goes a long way and it doesn’t weigh my hair down. Definitely worth it if your hair needs repair. ✨

Growing baby hairs!

I apply this to the balding part of my scalp and then use a scalp massager for several minutes. My balding spots are growing hair - I never thought this would happen!

Great serum that doesn’t leave scalp oily

Wonderful serum, to my surprise it doesn’t leave hair looking oily which is such a positive. My hair feels healthy and I can see it growing. This helped me get some length

Great one

This is a great product for your hair I ever using it since last September really good

It works!!

I am beyond impressed with the results! I’ve already started noticing new hair growth, which is such an amazing feeling. The baby hairs are coming in and everything feels healthier and stronger overall. It’s clear that the treatment is actually working. Highly recommend to anyone looking for real results. 💛

Healthy Roots!

This product does an amazing job at strengthening and lengthening my hair. When I use it regularly I notice a difference in the amount of hairfall that I get as well as the overall quality and thickness of my hair. This is a must in my haircare routine!

I’m not impressed

I’ve been using for a few weeks & not loving this product. I prefer the hair oils I’ve purchased. I stopped using as it gives my scalp a build up.

Produit exceptionnel c'est pour ca en ruptureu

Incredible product

Wish this came in a bigger bottle! It has become a part of my regular routine. Great for hair that blow dries and uses lots of product.
