Male pattern baldness has seven stages, which you can identify using the Hamilton-Norwood scale:
- First stage: Little or no hair loss or hairline recession.
- Second stage: Slight hair loss near the skin between your ears and forehead (temples).
- Third stage: Deep hairline recession around your temples, and your hairline may have an “M” or “U” shape.
- Fourth stage: Very deep hairline recession and hair loss at the top of your head (crown).
- Fifth stage: Your hairline recession connects to the bald spot on your crown.
- Sixth stage: The hair between your temples and crown is thinning or gone.
- Seventh stage: No hair on the top of your head and a thin band of hair around the side of your head.
