Masque Thérapiste

Masque for thick over-processed hair

Masque Thérapiste

The rich, reconstructive, velvety texture of this masque fuses onto the hair to fill it with reparative complexes that restore the fiber. Comforted and revitalized, the fiber feels almost virginally pure. Through it's rich buttery texture offering a sensation of comfort, thick hair looks livelier and more vibrant.

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 Saved my hair I bleached the cr*p out of my curly, fine hair. My curls were gone and all that was left was a SUPER dry, poufy ball of yarn. I figured I would give this a try (a very expensive try - this stuff ain't cheap) and it WORKED. My curls are back and soft. I also liked that it didn't turn my hair that yellowy color. I'm really happy that I found something that fixed my hair! December 17, 2016
Rated 5 out of 5 by Wow! This is an extremely potent hydrating mask! I have thick, frizzy, curly hair that I tend to use a lot of heat on just to get under control, and most conditioners/masks, even Kerastase's own Masque Magistral and Masquintense Thick (as well as the now discontinued Oleo Relax Slim) have done very little for my hair. This though left my hard-to-manage strands uncharacteristically easy to detangle and pretty much silky smooth to the touch. I don't know how repairing it is, although I will say it does provide a solid coating on hair, which in turn no doubt helps protect it from the potential damage any heat styling may cause. Ultimately though, and I never thought I would ever say this, but I actually think this mask might even be too hydrating for me to use regularly! I will certainly keep it in rotation however, and use it as a once-a-month pitch hitter to bring life back to my locks. All in all, definitely worth a try if you struggle with difficult to manage hair! December 7, 2016
Rated 2 out of 5 by Scent way too strong! While this mask softened my hair the scent was too strong for me to want to use again. During the day my nose itched and started to run I was so sensitive to the smell. Its like perfume was dumped into the product. November 28, 2016
Rated 5 out of 5 by Love love love I received this as a sample from influencer. This was a great mask. I was disappointed that it didn't have a scent but it had great results. November 1, 2016
Rated 3 out of 5 by Great product but the fragrance... I love the effects of this masque on my hair - shine, manageability, reduction in frizz - everything I could want - but the fragrance is not super-appealing. I prefer more organic/essential oil smelling products - or if perfume is necessary, that it be light - this fragrance was so strong that I had to wash my hair again to get it out. Again - love the product's effects, but the strong fragrance is a serious bummer. I have used Kerastase for years, but it seems as if the fragrance changes over the past year have left the products smelling like drugstore products instead of the high-quality luxe products they are.

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.

• SP 94, supplies the follicle with the energy necessary to activate KAPs synthesis
• 6 amino-acids characterized by their capacity to attach themselves to damaged areas of the hair
