MALE PATTERN HAIR LOSS
Male Pattern Baldness occurs to 90% of males within their lifetime from the ages of 20 - 60 years.
Hair loss occurs by a pattern of a receeding hair line or thinning crown, due to follicular exposure to androgens (testosterone,androsteinedione & dihydrotestosterone (DHT) which causes progressive follicle miniaturisation, together with a reduction in the anagen (hair growing) phase.
Fine whispy hairs known as Vellus hairs are created and remain on the scalp, which gives the appearance of thinned hair. This condition is usually inhereted by one or both parents, so if there is baldness in your family line you a significantly more at risk and should seek treatment early to gain the best results
Experts often refer to the Hamilton-Norwood Scale to help men understand the progression of male pattern baldness. This scale groups men’s hair loss into seven classes from the least amount of hair loss to the most.
There is minimal or no recession of the hairline. At this stage, you should monitor your hair regularly for any signs of thinning.
The initial signs of hair loss are becoming more visible. The hairline starts to recede, typically in symmetrical triangular shapes near the temples, like an “M” shape.
There is deep symmetrical hair loss at the temples, which may be bare or sparsely covered with hair. At this stage, the hair also begins to thin at the crown.
Hair loss in the frontal region and at the temples becomes more severe. Additional thinning is visible near the hairline and thinning at the crown becomes more pronounced. A moderately thin band of hair separates the two areas of hair loss.
There is still a visible separation between hair loss in the front and at the crown. However, the divide is becoming narrower. A “horseshoe” shape of remaining hair at the sides and back of the head is beginning to form.
More severe hair loss is clearly visible, as the hair separating the crown and the front temporal region is nearly gone with only sparse hair remaining.
This is the most severe form of hair loss. There is a complete loss of hair in the front, temporal and crown regions. The “horseshoe” shape of hair is all that remains, and the hair remaining may be less dense than it was previously.
