What should you know about dihydrotestosterone hair loss?

DHT is made from testosterone and acts on follicles that are sensitive to it. In those follicles, growth phases may become shorter and hairs may become finer, especially around the temples, hairline, or crown. This pattern is associated with Male Pattern Hair Loss and can also be relevant to Female Pattern Hair Loss, although distribution and hormone context differ.

DHT is not the explanation for every episode of shedding. Alopecia Areata can cause smooth patches, Telogen Effluvium can follow a body stressor, Scalp Ringworm may cause scaling or broken hairs, and Traction Alopecia can follow repeated pulling. A clinician may examine the scalp, review family history and medicines, and check for inflammation or scarring.

Arrange an assessment if thinning is persistent, patchy, sudden, or accompanied by itch, scale, pain, or scalp redness. Bring a list of medicines and describe recent illness, major stress, restrictive dieting, hairstyle tension, and family patterns. Treatment depends on the diagnosis. Finasteride Treatment may be discussed for some people, but it requires an individual review of benefits, risks, pregnancy considerations, and other medicines. Avoid starting hormone-related treatment without professional guidance.

Seek prompt review for rapidly developing patches, scalp pain, pus, marked inflammation, broken hairs with scaling, or loss of eyebrows or eyelashes. A shiny area with reduced follicle openings can suggest scarring, where early assessment matters. Sudden hair loss with weakness, unexplained weight change, or other new body symptoms also deserves medical evaluation.

Ask whether the pattern fits androgenetic alopecia or another cause, whether blood tests or a scalp examination are useful, and what treatment timeline is realistic. Discuss sexual or mood effects, pregnancy precautions, and what would happen if treatment is stopped before choosing a DHT-related option.
