Role of genetics in premature hair loss

The scientific name for the genetic tendency for hair loss or pattern baldness is Androgenetic Alopecia, the main cause of premature hair loss in 95% of men and women in the modern world, it is premature hair loss is seldom noticed. In addition to genetic predisposition, there are a number of other causes such side effects hair loss medication, radiation, pregnancy, age, or even improper hair care. You should carefully study the causes of hair loss and find out yourself.

Among other important reasons for hair loss is hereditary or Genetics play an important role. In fact, genetics is the prime cause of premature hair loss or pattern baldness is genetic in this standard by name, as "an example of male baldness", but also the most common form of hair loss or baldness in women, the two genders for baldness is Androgenetic Alopecia, scientific name disease.

As an example of baldness that men and women, there is increased hair loss, as more and more hair thins, and begins to telogen (resting) phase, instead of remaining in the anagen (growing) phase. Finally, the degree of hair loss is so severe, that manifesting itself in the form of baldness.

Physiology of androgenetic hair loss

Androgenetic hair loss is the main factor of 5 alpha reductase enzymes. There are two types of these enzymes, 5 alpha-reductase type I is located in the sebaceous glands, epidermal and follicular keratinocytes, dermal papilla cells and sweat glands. 5 a reductase II isoenzyme are located mainly in the root sheaths of the scalp.

Both types I and type II isoenzymes convert to testosterone, the male hormone into dihydrotestosterone (DHT), the most important, that stimulates androgen androgenetic pattern hair loss or balding. DHT attacks the hair follicles are genetically sensitive to frontal to occipital hair follicles, which are seen from the back of the scalp. It damages the normal density and eventually leads to shedding.

Androgen - sensitivity hair follicles

This is due to genetic reasons, that a certain part of the scalp hair follicles are androgen sensitive. It is after puberty, when the production of male hormones from the genetically sensitive hair follicles responds to male hormones and therefore leading to a pattern balding. Due to the action of DHT (the result of circulating androgens), and hair must be miniaturized and becomes more resistant to shedding.

Although DHT is the main cause of hair loss in men and women, the mechanism and causes of hair loss and male pattern balding in women is different.
