Kerastase Resistance Bain Extentioniste Shampoo - Length Strengthening Shampoo For Damaged Hair, Protects Hair and Scalp from External Aggressors

I always wait a couple months before I can honestly give a review for a beauty product that is this expensive. Preface: my hair is very long, thick and straight. I also have bayalage colors on the ends- so this also makes my hair somewhat dry/damaged. I wanted a product that would help strengthen the roots and also help with split ends. I have used Olaplex before this but I felt that Olaplex was not as effective anymore. Finally, I only wash my hair once a week. I did a lot of research on all of the available hair products that would my type of hair. I settled for Kerastase.I will also like to add: to make sure that this is effective for you, understand that their are companion products to this that make it work. Not only just the shampoo, but the conditioner and the hair serum afterwards (see photos). So develop a routine of using these 3 products and it will work. They all smell great (clean, almost cucumber smell) and they all are lightweight and don't weigh down my hair. My hair feels sleek and stronger compared to olaplex or store bought shampoo.CON: the size/amount of the shampoo. Since I have long hair, i use a lot of product. It lasted about two months. But again, I don't wash my hair everyday. Since this seems like a Euro-derived product, I will look at how much it is when I'm on that side of earth to see if it is cheaper. But I would recommend trying it.

For anyone who is looking to grow out their hair, this shampoo is a must have!! I understand the cost is high, but I have tried so many different brands, wasted money on different products, and nothing has really worked. This shampoo in less than 3 weeks had all my baby hairs growing, my hair felt stronger and softer. It’s expensive, but you will love your hair so I think that’s worth it.

Little bit pricey but definitely worth it!!

Perfecto para tener el pelo suave , rinde bastante y un aroma increíble

A little goes a long way, so the price is justified. Helps stop breakage, nice scent, and gives me gorgeous shine

My hair has been through it. Heat damage? Check. Questionable DIY dye jobs? Oh, absolutely. One ill-advised phase where I thought bleaching twice in one day was “no big deal”? We don’t talk about it.I expected this shampoo to try—like a weak apology from a toxic ex. But no. This stuff actually does the work. One wash, and my hair went from brittle despair to looking like it has a 401(k) and drinks green juice for fun. The ceramides? Magic. The shine? So disrespectful, I could blind my enemies with a hair flip.Would I recommend? Yes. But be warned—your hair is about to act like it never knew struggle.

Si ayuda al crecimiento del cabello.

It is very gentle, cleans thoroughly, and has a wonderful scent.
