The Real Hair Loss of Pathological Origin

The real hair loss of pathological origin is called alopecia.

Alopecia can be genetic or caused by male hormones. When hair loss is hereditary, it is called androgenic alopecia. Follicles inherit a particular sensitivity to the action of testosterone coupled to that of the 5 a-reductase and producing DHT (Dihydrotestosterone). Consequences are a disruption and acceleration cycle of the follicle affected, which will eventually weaken. The hair regrowth which is becoming thinner and will eventually disappear completely. But this large hair loss may also draw its origin in hormonal factors.

When it is caused under the influence of male hormones called androgenic, the alopecia is called androgenic. In fact, during our life, hormones fluctuate and they can influence the health of hair. These hormonal disturbances often occur with menopause, after childbirth, in the case of a thyroid disorder, and again after taking a contraceptive or substitutive therapy or other source of stress, which can cause an abrupt decrease of female hormones and a dominance of male hormones called androgens. However, it is important to emphasize that it is not necessary for hormone production changes to trigger alopecia, because it can also be an inherited hypersensitivity of the follicle, in such case one speaks of hyperandrogenic alopecia which is a disorder affecting about 70% of men.

In these cases, hair loss typically exceeds 50 to 100 hairs per day. It happens that there is less than 50 to 100 hair lost per day, but with a change in the volume of the hair or a change of hairline, causing the scalp to become more sparse or visible in places.

It concerns 80% of women and is the result of an unfortunate association between an excess of male hormones that form at the hairline and genetic predisposition. These hormones deplete the hair and cause his downfall.

Hormonal Imbalances

Resulting from pregnancy, following childbirth, during menopause, or in case of thyroid problems or slowing of pituitary function. Indeed, in hypothyroidism, there is an accumulation of fat and waste in the body. This oxidative stress disrupts the rhythm of the hair cycle and accelerates its final phase, the telogen phase, that is to say the death of the hair. The anagen phase, corresponding to its lifetime, is itself slowed. This results in hair loss and a slowdown in growth.
