Typical hair issues are hair loss (because of androgenetic alopecia, stress, or nutritional deficiencies), dandruff, hair breakage, and oily, dull, or split ends.

Alopecia or hair loss, can be due to various factors. Genetics plays a major role, particularly in male pattern baldness. Another common cause is aging, with men and women typically experiencing hair thinning as they age. Hormonal changes, during menopause or pregnancy, can also lead to hair loss. Certain medical conditions, like thyroid disorders or alopecia areata, and chemotherapy treatments, can cause hair to fall out. Stress, poor nutrition, and certain hairstyles that pull on the hair can also contribute.
