Hair loss, known as Androgenetic Alopecia, is often caused by hormones and can be diagnosed using noninvasive techniques. Treatments include topical minoxidil and oral finasteride, with new treatments being explored. There may also be a link between this type of hair loss and heart disease risk.

Future treatments for androgenic alopecia may focus on reactivating hair follicle stem cells and improving drug delivery.

The research found that male pattern hair loss is mostly genetic and involves hair thinning due to hormonal effects and changes in gene expression.

Scientists created cell lines from balding patients and found that cells from the front of the scalp are more affected by hormones that cause hair loss than those from the back.

Finasteride reduces hair follicle cell death in androgenetic alopecia.

Minoxidil, originally a blood pressure medication, is effective in treating hair loss in men and women, with different strengths recommended for each.

Exosomes from hair papilla cells and the Chinese medicine Liao Tuo Fang can potentially promote hair growth and could be used to develop hair growth drugs.
