Stages of Male Pattern Baldness
As the name suggests, Male Pattern Baldness (Androgenetic Alopecia) usually occurs in a recognizable pattern or stages, caused by male hormone DHT binding to Androgen Receptors on certain hair follicles. Hair loss is measured on the Norwood-Hamilton scale as depicted in the diagram below:
- 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
Why does Male Pattern Baldness occur?
Androgenetic Alopecia is mainly caused by genetic predisposition – the sensitivity of hair follicles containing Androgen Receptors to the male hormone DHT causes the hair follicles to miniaturize, resulting in loss of hair shaft calibre and hair
volume and ultimately causing baldness.
Androgenetic Alopecia is passed on via genetics from your ancestors on the father and mother’s side. A number of other factors also contribute to the final picture, making it a challenging situation.
In Androgenetic Alopecia, the enzyme 5α-reductase facilitates the formation of DHT from the male hormone, testosterone. The DHT binds with androgen receptors in the hair follicle triggering the process of miniaturisation of the affected hair follicles. Miniaturisation is the process whereby hair follicles become smaller causing the hair shaft calibre to diminish and the hair
shaft length to get shorter over time. Eventually the hair will become very thin and small like a vellus hair, then cease to grow and result in an area of baldness.

What can be done to prevent or cure Male Pattern Baldness?
There are a number of things you can do to prevent the process of male pattern baldness from progressing, such as changing your diet and using mesotherapy non-surgical treatments and medication. For more advanced hair loss, you may opt for minimally invasive hair transplant surgery, during which healthy hair follicles (which don’t contain Androgen Receptors) are harvested from the donor area of the scalp, and then transplanted into the recipient area.
The many successful results achieved by Dr. André Nel is confirmation that hair transplant surgery works well in the right hands.
