Rated 3 out of 5 by Appears to have stopped working The first 3 times I used this product, it made my long hair thicker, silky and shiny. Now I have used it 5-6 times and am not impressed. My hair is lanky, straight, not bouncy at all. Perhaps I am using it too often? If I cut-back and only use it once every two weeks, I will re-visit this review and re-confirm. September 28, 2015
Rated 5 out of 5 by Saviour for lightened hair I have coarse, curly, thick, dry hair that's also damaged from lightening. Breakage was getting out of control and I didn't want to give up lightening my hair so I bought the therapiste line (minus the serum), and its completely transformed my hair - breakage is a thing of the past. I couldn't be happier with a product. I use weekly with the pretreat from the same line as well as the bain. August 26, 2015
Rated 5 out of 5 by I love this product! The smell is amazing, the texture is so thick and creamy and coats every single hair fibre helping to rebuild and repair. I use it once a week for an ultimate hair treatment. The thickest hair mask Kerastase has created to date June 22, 2015
Rated 5 out of 5 by Best I use maskintense for many years,after they reformulate it I didn't get the same results,try the new version and still no luck,try this one and I was so surprised, My hair was very damage from highlights and pregnancy,so I couldn't dye my hair for a wile,this is the best out of all the other masks I try them all, I don't think you can use this for a long term,just until you recuperate you hair,but I will continue for ever is just magical the first use you will see the difference in you hair, I do not love the smell thats the only down,the shampoo for this is so creamy I love it,and the pre shampoo helps a lot.

Rated 5 out of 5 by My go-to mask! My hairdresser had recommended this product to me, along with the shampoo and conditioner. I use this product after I condition and shampoo and I am completely in love. You only need a pea size amount and it goes over all of my hair so smoothly. Once I rinse it out I can see immediate results. My damaged, fine hair looks revitalized and shiny again! Thank you so much, kerastase! September 15, 2015
Rated 5 out of 5 by Miracle Product! I recently purchased the sample size of this product so I could try before committing to buy the larger size. I am 46 years old and have dyed my hair for many years. As a result, I have extremely dry hair which is frizzy in areas. However, after using this masque I could immediately see a significant difference and each time I used it, the texture of my hair improved. I will now be buying the large size with no qualms whatsoever. Highly recommend!!!! September 15, 2015
Rated 5 out of 5 by Literally Saving My Hair I love Kerastase products in general but I really love this product. My hair is so damaged from chemical processing and heat styling that it has gotten really dull and dry. I have the entire collection and it has literally given my hair a second life. It's moisturized my hair and returned it's softness and shine and smoothed out a lot of my split ends and reduced breakage. Love it! September 15, 2015
Rated 5 out of 5 by Great mask I come from a mixed background. I consider my hair 4c. I color it and get keratin treatments which is why I cannot use the shampoo which contains sulfates. So I bought the rest of the line. I use them all together. Although I don't think I need to. The mask itself can stand on its own. The first time I used it I left it on for 10 min. I noticed it was softer butting didn't last, I needed more. My hair is very fragile, colored, kinky curly. I have to blow dry and flat iron my hair to get it straight. So I left this mask on overnight on damp hair with a plastic cap. The next day I rinsed it out and OMG. My hair felt to soft and smelled so good. It was shinier and tangle free. After that, I started to use it once a week and I never had to use it overnight again although I do sometimes because my hair is in better shape everytime I use it. Very little goes a long way, even for fine, unmanageable, afro hair like mine. In comparison to other drug store brands, this does not leave a residue due to the fact it doesn't contain any silicones and is not as heavy. I do get balayage highlights and I did notice some bronzing to my blonde sections. I think it has to deal with the amount of time that I leave it on. September 8, 2015

The Masque Thérapiste is a unique butter texture masque that works at the very core of the hair.
FOR WHO? For very damaged and over-processed hair (erosion level 3-4). Dedicated to thick hair.
WHAT DOES IT DO ? • The hair is deeply repaired as its core. • The hair fiber regains its strength and elasticity. • Hair is toned and revitalized


Apply to washed and towel-dried hair applying the product section by section throughout the length of the hair.
Massage onto lengths and ends.
Leave in for 5 minutes, emulsify and rinse thoroughly.

For a deeper ritual:

Before applying the shampoo Bain Thérapiste, use the Soin Premier Thérapiste which plays the role of a smart starter. Formulated to bind the hair in the manner of a protective gauze, it works upstream to infuse the fiber with softness so it is protected during the rest of the cleansing routine.
