KERASTASE Résistance Masque Thérapiste Hair Mask 200ml

KERASTASE Résistance Masque Thérapiste Hair Mask 200ml is an intensive repairing hair mask specifically developed for very damaged, over-processed and highly sensitised hair.

Its rich, buttery texture penetrates the hair fibre to help rebuild weakened structure, restore strength and improve elasticity. Hair is left feeling softer, smoother, stronger and revitalised, while the formula helps protect against future breakage.

Unlike a standard nourishing mask designed mainly for dryness, Masque Thérapiste is targeted toward advanced hair damage caused by repeated chemical or mechanical stress.

Repair → Rebuild → Strengthen → Restore Elasticity → Reduce Breakage → Smooth

What Is It?

Masque Thérapiste is the intensive treatment step within the KERASTASE Résistance Thérapiste collection.

Kérastase specifically positions Thérapiste for very damaged and over-processed hair, while Force Architecte is intended for less severe levels of damage. The brand describes Thérapiste as targeting erosion levels 3–4, compared with Force Architecte at levels 1–2.

This distinction matters.

Masque Thérapiste is not simply:

“A mask for dry hair.”

It is better positioned as:

“An intensive rebuilding mask for severely damaged and over-processed hair.”

That should be the central marketing message on Peggymou.
