KÉRASTASEResistance Therapiste Hair Mask, Repairing Cream for Weak, Over-Processed and Damaged Hair, Strengthens and Deeply Nourishes, Protects Against Breakage for Weak Hair, 6.8 Fl Oz

I made the mistake of trying to color my hair at home. After several poor attempts, my hair was FRIED! It looked like cotton candy. I started using this at night as a leave in just applying it sparingly. It has completely changed the texture of my hair. It’s expensive but a little goes a long way if you use it on dry hair where needed. It’s worth every penny!

The best!! Life changing

I have long Grey course hair and a mind of it's own.

Me encanta hidrata full y deja el cabello suave y brillante

Very good quality product

Maravilloso

this is my first Amazon review I have ever written. I have extremely damaged hair, I was a platinum blonde for years & have natural brown hair. I have been using this mask (I use it as conditioner) & the same shampoo from the extensioniste line for just about THREE YEARS. The first photo is from Nov 2021 before starting using this hair mask & kerastase line & the second is my hair in May 2023. It has helped repair my damaged hair & keeps my hair so soft. I can’t recommend this entire line enough. It is worth every penny, if you have damaged hair, you can’t afford to not try it! I’ll warn you, I haven’t bought anything else sense though!

My hair stylist turned me onto this product four years ago. My hair always feels silky soft after a treatment. This is the same product I would buy at the salon. Now that my stylist has gone out on her own, there is no reason to make the trip to the salon. The fragrance is a bit strong, but it melts away in a day or two, leaving your hair smelling fresh that much longer.Keep in mind that the jar for the Masque Extentioniste is very similar in colour, so it would be easy to mistake one for the other unless you view them side by side. I accidentally bought the Extensioniste from a brick and mortar. After getting home and applying it to my hair, I noticed that it smelled lighter and kind of fruity. I was afraid they had changed the formula. Thankfully, I realised that I purchased the wrong product. They are both excellent products, but my preference is for the Masque Therapiste.
