Nourish High Nutrition Mask is a creamy, buttery mask that intensely hydrates dry and thick hair. Plenty of people complain of dry, unruly hair, a condition that occurs when the hair fiber doesn't receive enough sebum from the scalp; this leaves the hair fiber devoid of its usual hydrolipidic film, which acts as a protective barrier. In such a state, the hair grows vulnerable to external factors such as solar radiation and pollution; in turn, these contribute to dry the hair even further. Not only does the hair becomes brittle and coarse to the touch, it begins to look dull and lifeless.
