Kérastase Resistance Therapiste Hair Mask

Kérastase Résistance Masque Thérapiste is the brand's most intensive repair treatment — designed specifically for very dry, over-processed hair that has been significantly damaged by bleaching, chemical processing, or excessive heat. The ceramide and protein complex works to rebuild the hair's internal structure while the lipid complex restores the surface.

We tested this on severely bleached hair and found it one of the most effective repair treatments available. After three weekly treatments, the hair's texture was noticeably improved — less brittle, more elastic, and significantly shinier. The mask has a rich, creamy texture that feels luxurious during application.

At current pricing for 6.8 oz, it's a significant investment, but for those with genuinely damaged hair who need serious repair, Masque Thérapiste delivers results that justify the cost.
