Hair masks are deep conditioning treatments that nourish and rejuvenate your hair follicles. Most of their creamy formulas feature hydrating ingredients that will replenish the lost moisture in your hair, especially for split ends and frizz. The job of a hair mask is to deliver a concentrated dose of conditioning for dry, damaged, or overly colored and processed hair. Not to be used as a replacement for your standard conditioning processes, this unique formula provides a potent boost of moisture, aimed to speed up the healing process for your damaged locks.
