Male pattern baldness |
| Overview Symptoms Treatment Prevention |
| Alternative Names: |
| Alopecia in men; Baldness - male; Hair loss in men |
| Symptoms: |
|
The typical pattern of male baldness begins at the hairline. The hairline gradually recedes to form an "M" shape. The existing hair may become finer and shorter. The hair at the crown also begins to thin. Eventually the top of the hairline meets the thinned crown, leaving a horseshoe pattern of hair around the sides of the head. Hair loss in patches, diffuse shedding of hair, breaking of hair shafts, or hair loss associated with redness, scaling, pain, or rapid progression could be caused by other conditions. |
| Signs and tests: |
|
Classic male pattern baldness is usually diagnosed based on the appearance and pattern of the hair loss. Any atypical hair loss may be caused by other medical disorders. A skin biopsy or other procedures may be needed to diagnose other disorders that cause loss of hair. Hair analysis is not accurate for diagnosing nutritional or similar causes of hair loss. However, it may reveal substances such as arsenic or lead. |
