The causes of hair loss are plenty including diseases,
nutritional deficiencies, hormone imbalances, and even stress.
But, one of the most common ones is adrogenetic alopecia.

Alopecia, is in fact, the term for hair loss. Androgenetic is a
reference to the fact that factors such as a genetic
predisposition to balding and the influence of male
hormones-androgens-play a part. There is also a third
aspect-aging. Let's look at these in brief: Genetics Genetics is
a complicated thing and not easy to understand or predict the
behavior of. The case with balding is also the same. Simply the
presence (or absence) of balding in one's parents, on either,
the mother's or father's side, is not necessarily predictive of
one's likelihood of balding. It's very hard to accurately
predict who will go bald and how rapidly. Androgenic Hormones
All normal men and women produce "male" hormones. The most
common of these are testosterone, androsteinedione, and
dihydrotestosterone (DHT). These hormones are quite important in
both sexes, but occur in different concentrations, being much
more predominant in males than in females. This, in part, is
responsible for the typical differences between the genders. It
is the exposure of the hair follicles to DHT, in a genetically
susceptible person, over a period of time, which leads to
androgenetic alopecia, or male and female pattern baldness.
Aging Age and balding are not proportional in any manner
imaginable. It is a process and this fact should not be ignored.
Like any process, it can be rapid or slow, it can begin toward
the end of life or in the late teens, and it can progress in a
predictably inexorable fashion, or it can stop and start,
seemingly stabilize, and then begin again. But what exactly does
happen? Assuming we have a genetically predisposed person, then
as the follicles are continuously exposed to DHT, an interesting
phenomenon occurs. The anagen phase, or active growth phase of
the hair becomes gradually briefer and briefer, and eventually
the hair becomes finer and shorter, and less deeply colored.
This is called "miniaturization" of hairs. This is also the
point at which hair loss tends to be noticed first. It's not
that there are fewer hairs on the head, but that their caliber
(cross-sectional area), color and length are so diminished that
they no longer provide "coverage" for the scalp beneath.
