Men usually lose hair for the following reasons:


  • Male pattern baldness (androgenetic alopecia)
  • Heredity/family history of hair loss


  • Hormonal changes
  • Traction alopecia (usually from braiding or weaving)
  • Medications (chemotherapy and radiation, as well as high blood pressure and heart medications)
  • Medical conditions (i.e. alopecia areata, a patchy hair loss that is the result of an autoimmune disease in which the immune system attacks hair follicles)
  • Extreme stress can trigger hair loss

The Norwood Scale – Hair Loss Classification

The Norwood scale is a visual measure that is utilized to identify the severity of male pattern hair loss. It is important to note that hair loss treatments are most successful when started early; the sooner you meet with a specialist about your hair loss, the greater your chances become of preserving the most hair.

Class 1: No visible hair loss
Class 2: Hair begins receding at the hairline and in the temple region
Class 3: More significant hair loss at the hairline and on the sides of the head (in the temple region)

Class 3 vertex: Hair loss is also significant on the top of head (crown)
Class 4: Significant hair loss above the temples and forehead; more noticeable hair loss on the crown
Class 5: Extreme hair loss; only a small area of the front of the head remains; area of hair loss on the top of the head is large
Class 6: There is no or barely any hair bridging the two sides of the head; while there may still be sufficient donor hair, results may be limited
