Masque

A hair
masque is an intensive deep-conditioning treatment with higher concentrations
of proteins, emollients, and humectants than a standard conditioner. It
penetrates the cuticle to repair damage, restore elasticity, and deeply
hydrate dry, porous, or color-treated hair.

Yes, you
can swap your conditioner for a masque on wash day once or twice a week. On
other wash days, stick with a regular conditioner so hair gets both surface
smoothing and deeper weekly repair without becoming over-conditioned.

The best
masque for damaged hair combines proteins (keratin, hydrolyzed wheat) to
rebuild internal structure with emollients (shea butter, argan oil) to
restore softness. Look for formulas labeled repair, bond-building, or
deep-repair treatment.
