Male Pattern Baldness
Male Pattern Baldness is the most common form of hair loss in men. With Male Pattern Baldness, hair tends to diminish at the front, top and crown of the scalp (the ‘non-permanent’ area) but will continue to grow in around the sides and back (the ‘permanent’ area).
The Science bit;
The male hormone dihydrotestosterone (DHT) stimulates the hormone receptors in the non-permanent area, which alters the life cycle of the hair root, therefore prompting hair loss. Ordinarily, the hair cycle consists of a ‘growing phase’ lasting up to 7 years and ‘resting phase’ lasting 3-4 months. Genetic hair loss switches this cycle around, meaning the growing phase gets shorter and shorter and the resting phase increases. Eventually, there’s very little hair left.
Norwood Classification of Hair Loss in Men
A youthful hairline that has not lost any hair, resting just above the upper forehead.
An adult hairline has formed, sitting approx. 1.5cm above the upper forehead crease, with some temporal recession.
The temporal recession is increasing to the point of concern. Here’s when you consult a doctor.
Type 3 Vertex:
This type of hair loss signifies the earliest signs of hair loss at the crown.
Further hair loss at the front and crown.
The gap at both the front and crown are getting larger. The bridge between the two areas is breaking down.
The bridge has now completely disappeared, where a sizeable bald area now exists on the top of the scalp.
Widespread hair loss with only a garland of hair remaining in the permanent area.
