Stages of Male Pattern Baldness


As the name suggests, Male Pattern Baldness usually occurs in a certain pattern or stages, caused by male hormone binding to Androgen Receptors on certain hair follicles. Hair loss is measured on the Norwood-Hamilton scale as depicted in the diagram below:

Stages of Male Pattern Baldness

  • Type II: Slight hair loss occurs at the temples (progression of the hairlines), with little to no effect on the appearance.
  • Type III: Usually, showing a symmetrical recession at the temples.
  • Type III vertex: Visible receding hairline and thinning hair on the vertex (highest point of the hairline / front of head).
  • Type IV: Deepening of the hair loss at the temples occur, thus presenting a bigger pattern on the vertex and hairline.
  • Type IVa: More pronounced hair loss in the fronto-temporal and crown area.
  • Type V: The bald patches in the front and crown areas continue to enlarge and the bridge of hair separating the two areas begins to thin and break down.
  • Type VI: The connecting bridge that separated the frontal hair line and crown has disappeared, but several strands of short fine hair may remain.
  • Type VII: Type VII is the most advanced form of hair loss on the Norwood-Hamilton scale

Understanding the progression of hair loss will help to determine the best course of action for the individual that is experiencing Androgenetic Alopecia. The stage of hair loss will ultimately determine the treatment plan required.

Why does Male Pattern Baldness occur?

Androgenetic Alopecia is mainly caused by genetic predisposition – the sensitivity of the hair follicles to a specific male hormone causes the hair follicles to miniaturize, which then causes the hair to thin and ultimately prevents the hair from growing.

What can be done to prevent or cure Male Pattern Baldness?

There are a number of things you can do to inhibit the process of male pattern baldness from progressing, such as changing your diet and using non-surgical treatments and medication. For more advanced hair loss, you may opt for a minimally invasive hair transplant surgery, during which healthy hair follicles are harvested from the donor area of the scalp, and  then transplanted into the recipient area. See below the various treatment options for hair loss:

  • Hair loss supplements: Hair loss supplements from Help Hair, consisting of whey protein and essential vitamins and minerals that promote healthy hair growth.
  • Hair loss medication: A hair restoration specialist can prescribe an FDA approved prescription medication for combating hair loss, and this can be done in combination with surgical and other non-surgical hair loss treatments.
  • Trichology products: A variety of hair care products have been developed by Help Hair and CR Laboratories to promote healthy hair growth.
  • LaserCap: The LaserCap® LCPRO™ and LaserCap® LCElite™ are medical devices that use Low Level Light Therapy to promote hair growth.
  • CRL Medical Hair System: A CRL Medical Hair System can be used to add hair volume in cases where hair transplant surgery options are limited or not possible. Read more about this hair replacement system and what it can do for you.
  • Scalp micro-pigmentation: Scalp micro-pigmentation involves placing color pigments on the scalp (similar to a very superficial tattoo dot), that minimizes the reflection of light from the scalp and creates the illusion of hair density.
  • Hair transplant surgery: Hair transplant surgery is a permanent hair restoration option for hair loss and the harvesting can be done via FUE or FUT or Combination FUT/FUE techniques.
