There are numerous reasons why people lose their hair. Depending on what’s causing your baldness, your hair may: thin, fall out gradually or suddenly, can recover on its own, needs therapy to do so, and requires prompt attention to prevent permanent hair loss.

Hair loss can occur gradually or abruptly, resulting in thinning or bald spots. Hereditary hair loss, or androgenic alopecia, is the most common cause of hair loss worldwide, affecting both men and women. The condition is caused by inherited genes that shrink hair follicles, eventually stopping hair growth. While thinning or a widening part is the first noticeable sign of hereditary hair loss in women, a receding hairline or bald spot at the top of the head is common in men.

Treatment can help slow hair loss and promote hair regrowth, but the earlier the treatment starts, the better the results. Without treatment, hair loss will continue.
