What is hair loss? Â

Seborrheic alopecia is clinically known as androgenic alopecia. The symptoms of androgenic alopecia include thinning hair, increased scalp oil secretion, scalp itching, etc.

1. When

androgenic alopecia occurs in patients with thinning hair, dihydrotestosterone destroys hair follicles, which may cause hair thinning during growth time and shorten the growth cycle.

2. Increased scalp oil secretion

Androgenic alopecia can cause androgens in patients to be converted into dihydrotestosterone, stimulating sebaceous glands to secrete oil, resulting in increased scalp oil secretion.

3. Excessive accumulation of oil in patients with scalp itching

may stimulate scalp and nerves, causing nerves to transmit itching feelings to the brain, causing symptoms of scalp itching.
