Androgenic alopecia for men and women

Androgenic alopecia is a disorder related to androgens (male hormones) and to heredity. This type of baldness first appears in the hairline and later in areas such as "the entrances" and "the crown".

Androgenic alopecia leads to thinning of the hair, that is, the bulb and the body are diminished, producing fine hair, very similar to the hair on the rest of the body.

Likewise, the color is also altered, causing the affected area to lose pigmentation and may appear bald before the hair falls out. In addition, there is a reduction in the number of hairs in the anagen or growth phase and an increase in the follicles in the telogen or resting phase.

Male androgenic alopecia

In the case of men, it is known as common alopecia because it affects men the most. This is because the hair follicles are more sensitive to androgens (male hormone).

Hair loss can occur at any time after adolescence and the earlier it appears, the worse your prognosis. Normally, this pathology begins between the ages of 20 and 30.

This type of baldness is present in men with high levels of DHT (dihitrotestosterone) in their hair. This hormonal derivative causes the hair to not reach its normal size or thickness. In addition to those mentioned, racial differences are also observed in the incidence of alopecia patterns.

Female androgenic alopecia

Alopecia is a problem that traditionally has concerned men above all, but is increasingly common in women.

In the case of female androgenic alopecia, the age of onset is usually later and the first symptoms appear between 30 and 40 years. Although it is very similar to that suffered by men, this type of baldness progresses more slowly in women. In addition, it has a different distribution and usually manifests itself more in the central part of the head and not in the frontal line and in the area of ​​the "entrances", as it happens with men.

As in the case of men, it is women with high androgens who suffer it (eg, polycystic ovary). In addition to the genetic origin and the presence of DHT, other factors can cause baldness, such as hormonal changes (loss of estrogens in menopause), alterations in the capillary cycle, iron and micronutrient deficits, alterations in the menstrual cycle, etc.


Despite all that this type of alopecia entails, the root of the follicle remains alive, so normal growth can be reactivated, stopping the process and even recovering part of the lost hair.

The most effective techniques to combat androgenic alopecia are:

  • Treatment with medications: such as topical minodixil and oral antiandrogens aimed at correcting hormonal changes.
  • Mesotherapy with PRP: highly effective in improving blood flow to the scalp, essential for healthy hair growth.
  • Hair transplantation: if the rest of the treatments have failed, the graft is the solution to repopulate those areas that have irreversibly lost hair density.
