Hair loss can be categorized into two main types: androgenetic alopecia and alopecia areata. Androgenetic alopecia is the most common form of hair loss, accounting for approximately 95% of all cases. It is caused by a combination of genetic and hormonal factors, and is characterized by a receding hairline and thinning hair on the crown of the head.

Medications such as minoxidil and finasteride have been shown to be effective in promoting hair growth and reducing hair loss.
