Nourish Light Nutrition Mask is a nutrient-rich mask especially designed for dry and fine 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. The hair grows vulnerable to external factors such as solar radiation and pollution; in turn, these contribute to dry the hair even further. In such a state, fine hair requires extra care, as the application of excessively rich products can weigh it down and cause it to lose its natural volume.
