The most important symptom that characterizes oily hair and seborrheic skin is excessive sebum secretion. Normally, it occurs during adolescence, affects both sexes, and, in most cases, resolves spontaneously over the years. The products of this specific line contain a molecule of liquid active sulfur and a derivative of zinc salts. These particular active ingredients normalize the most superficial stratum corneum, regulating the amount of excess sebum on the scalp and hair. Excessive sebum secretion can shorten the life cycle of hair. The sebum that accumulates around the hair bulb suffocates it and reduces its reproductive function.
