What should you know about genetic male pattern baldness?

In androgenetic alopecia, genetically sensitive follicles respond to androgen signals by producing progressively finer, shorter hairs. The change commonly begins at the temples or crown and can make the hairline recede, though the pattern differs from person to person. The scalp usually looks healthy rather than inflamed. Family history can offer a clue, but a clinician should also consider other causes of hair loss, including illness, nutritional problems, medicines, or scalp disease. Earlier assessment helps distinguish gradual pattern loss from a sudden process.

Take clear photographs in similar lighting so changes are easier to discuss at review. A dermatologist may examine the scalp and hair shafts and decide whether blood tests or another assessment is appropriate. Treatment choices depend on age, health, pregnancy considerations for a partner, goals, and the amount of existing hair. Options may include prescription finasteride, low-level laser devices, or hair restoration surgery. Medicines need consistent use and a discussion of possible adverse effects; transplanted follicles do not prevent thinning in untreated surrounding hair. Gentle washing and avoiding tight styling help limit additional traction.

Book an assessment when loss is rapid, patchy, associated with scalp pain or scaling, or accompanied by eyebrow or body-hair changes. Seek prompt care for a shiny tender scalp, bleeding, pus, or marked inflammation. These features can point away from uncomplicated genetic pattern loss and may need treatment before follicles are permanently damaged.

Ask whether your pattern matches androgenetic alopecia, what benefit and monitoring to expect from each option, and how treatment may affect sexual health or family planning. Discuss whether a transplant is suitable and how to protect remaining hair.
