About this item:

The TRESmé Keratin Smooth hair mask is a deep-conditioning treatment designed to fight frizz and smooth hair with a formula enriched with keratin and argan oil. It aims to provide five key benefits: fighting frizz, detangling knots, boosting shine, adding softness, and taming flyaways, resulting in silky-smooth hair with natural movement. The mask is intended for weekly use and works by smoothing the hair cuticle to make strands stronger and more manageable.

Fights frizz: Helps to tame frizz and flyaways for a smoother, sleeker look.
Moisturizes and softens: Deeply nourishes hair, adding softness and a silky feel.
Detangles: Makes it easier to comb through and detangle hair.
Boosts shine: Enhances the hair's natural shine.
Fortifies: Repairs damage and strengthens strands from the inside out.
