Hair Loss in Male and female

female hairloss:

Secondary circumstances can be at the origin of hair loss or can contribute to the effects of hereditary pathology.
It is important to find out which of the following causes are at play:

The hair loss can be due to a hormonal unbalance.

* Hyperthyroidism (insufficient thyroid hormones)
* Hyperandrogeny (too many male hormones)
* Hypo-oestrogeny (insufficient female hormones) which explains the hair loss in post-menopausal women.

The hair loss can be due to a mineral or vitamin deficiency :

* Iron, copper, magnesium deficiency,
* Vitamin B deficiency
* Protein deficiency
Or
even some unusual afflictions:

* Alopecia aerata ,lupus, alopecia, tinea.
* Hirsutism : the problem strictly occurs in women.
Hair recession in the anterior-temporal line.
With or without signs of virilism: male hyperpilosity in the rest of the body, acne, deeper voice, amenorrhea (absences of periods), hypertrophy, reduction of breast volume.
* Compulsive disorder: the female patient tears out her own hair (this may be compared to people who bite their nails).
* Alopecia of traction: often occurs in black women,
* Cicatricial Alopecia (for example after a burn)

male hairloss:

This is the cause of hair loss in men in over 90% of cases. MPB is defined as hair loss at the front, top and/or the crown/vertex of the scalp (non-permanent area). The back and sides of the scalp are spared and usually grow hair for life (permanent area).

The hair root has a life cycle. In simple terms this cycle consists of a growing phase and a resting phase. Before hair loss sets in, the growing phase lasts up to 7 years and the resting phase 3 to 4 months. Genetic hair loss causes the life cycle phases to go in reverse, i.e. the growing phase becomes shorter and shorter and the resting phase longer. Eventually the hair grows very little or not at all.

The cause of MPB is the presence of hormone receptors in the hair roots of the non-permanent area. No such receptors exist in the permanent area. These receptors attract the male hormone, dihydrotestosterone (DHT) and as a result starts the hair loss process. The number and location of these susceptible hairs is determined by inherited genetics from both or either parent. The scalp is the same all over and is usually rich in blood supply and therefore, contrary to commonly heard myths, MPB has nothing to do with lack of blood.
