Male Pattern Hair
Loss - The Basics
Although there are many causes of hair loss, such as
hereditary, stress, frequent usage of harsh hair care
products, the most common form of hair loss, Androgentic
Alopecia, or male pattern baldness, is experienced by
over 70% of Caucasian men, 50% in Asian men and about 30
to 40% in African Americans. Male Pattern Baldness (MPB)
represents close to 95% of all hair loss among males.
Androgenetic, consist of ANDROGEN (The hormones that
control the appearance and development of masculine
characteristics such as testosterone) and GENETIC and
AGE.
Male hair loss usually occurs at the front and at the
vertex of the scalp with these signs and symptoms:
- Thinning and fine hair;
- Receding hairline
- Moderate to extensive loss of hair, especially on the
crown areas.
Male pattern hair loss usually starts with the hair at
the temples, which gradually recedes to form an
"M" shape. Hair becomes thinner and does not
grow as long as it once did. Sooner or later, hair loss
also starts at the crown area of the head. As the
condition progresses, the point of the "M"
continues to recede, while the bald spot at the crown
widens. Eventually, the thinning crown and receding
point may meet. Eventually, a horse-shoe pattern of hair
appears around the sides of your head. Usually, the
remaining hair in the balding areas is thinner and grows
very slowly, the form of hair also changes from long,
thick, coarse, pigmented hair to short, fine and
colorless baby hair .
A receding hairline can reflect age, but not necessarily
occurs at old age, more and more young men have
experienced hair loss. Many of them experience receding
hairline or even baldness before their thirties. Since
male pattern hair loss is mostly related to hereditary,
a man can usually, although not always, predict the
extent of his future baldness by looking into his family
hair loss history.
Current scientific study shows that when age coupled
with genetics, it represents a time clock that will
signal the hair follicle to produce an enzyme named 5
alpha reductase. When the testosterone present in the
follicle combines with the enzyme 5 alpha reductase, it
produces dihydrotestosterone (DHT). Hair follicle
receptors are very sensitive to DHT and they genetically
shrink when exposed to excessive DHT. As the follicles
become smaller, the hair growing phase shortens and the
dormant phases lengthen, therefore the hair becomes
increasingly thinner and less firmly rooted. Then the
process of male pattern hair loss starts |
