The Norwood scale, explained
The Norwood scale is a seven-stage way of describing male pattern hair loss. These four classes are where most transplant consultations begin. Your own pattern may sit between two classes.
Class 3
The first class with clear loss. The hairline recedes at the temples in an M or U shape. Many people first consider a transplant here.
Book a consultation for class 3 →Class 4
The hairline has receded further and there is often thinning at the crown, separated from the front by a band of hair.
Book a consultation for class 4 →Class 5
The front and crown areas are larger and the band between them is narrower and thinner.
Book a consultation for class 5 →Class 6
The band has largely gone and the front and crown loss has joined into one large area. Planning matters most at this stage because donor hair is finite.
Book a consultation for class 6 →Female hair loss follows different patterns. Not sure where you fit? →
