Hypersecretion of sebum occurs during puberty in men and during menopause in women.Ģ) metabolic disorders (nutrition and elimination): a high-fat diet alters the body’s metabolic activity which protects itself by eliminating excess fat thanks to the exocrine glands (the sebaceous glands produce more sebum than normal, resulting in hyperseborrhea).ģ) digestive problems (hepatic or intestinal dysfunctions): these alterations change the chemical composition of the sebum produced, making it unusable or inadequate to protect skin and hair. Therefore, it is thought that hormonal imbalances of the thyroid gland and the pituitary gland could cause hyperseborrhea. Some of the factors that favor the appearance of hyperseborrhea are:ġ) hormonal imbalances: it is believed that seborrhea is also influenced by endocrine glands (internal secretion). The causes of hyperseborrhea have net yet been clearly defined. External environmental factors (heat increases vasodilation of scalp capillaries, producing increased blood flow and sebum production), wrong hair treatments (incorrect hygiene practices, treatments that are too aggressive or using the wrong products) or scalp infections may cause temporary hyperseborrhea. When hyperseborrhea is present for brief periods, it must not be considered a pathological condition as this problem may be resolved in a short amount of time. Lifeless skin, a condition that favors the appearance of comedones, occurs when excess sebum is not released and remains in the hair follicles, making skin rough and dry. On the other hand, when sebum production is in excess, normal sebaceous gland function becomes a skin problem, resulting in pathological seborrhea. If sebum secretion remains within certain limits, sebaceous gland activity is considered useful which is why it is called physiological seborrhea. Moreover, it moisturizes, protects and waterproofs the hair shaft. Sebum forms the hydrolipid barrier which has the function of protecting the scalp and hair from external environmental agents. Sebum secretion is a physiological process that starts in adolescence. They have the function of secreting sebum. The sebaceous glands are secretary organs located near hair follicles. It is important to distinguish between normal seborrhea and hyperseborrhea. It should be remembered that timely intervention is important in order to reduce and eliminate excessive sebum secretion by means of proper treatment capable of avoiding weakness and excessive loss of hair. In fact, its anagen phase becomes shorter and shorter until the follicles die and subsequently hair falls out. The fall and subsequent loss of hair occurs because excess sebum gathers and accumulates in the excretory ducts of the follicles, thereby blocking proper oxygenation of the hair and its normal growth and development.Īs a result of hyperseborrhea, hair gets thinner, shorter, duller and weaker with each growth cycle. Seborrheic hair loss is characterized by the presence of hyperseborrhea accompanied by hair loss. You can have simple blemishes, hair loss, acne, comedones or folliculitis. All of this leads to quite serious consequences.
