Excessive secretion of sebum is a common sign of oily hair and seborrheic dermatitis. It often occurs during adolescence and usually resolves with time. The products in this line contain an active liquid sulfur molecule and a zinc salt derivative. These ingredients help normalize the skin's outermost layer by regulating excess sebum production on the scalp and hair. Excessive sebum secretion can lead to a shorter lifespan of the hair shaft. The sebum that accumulates around the hair follicle can suffocate it and reduce its reproductive function. Therefore, it is important to use Silkat Sebo-regulator treatment products to regulate excess sebum secretion and keep the scalp and hair healthy.
