Today, hair loss is not only a problem for men, but a good percentage of women experience it at well.
“Female pattern androgenic alopecia” more simply known as female hair loss, follows a completely different pattern from male hair loss and it is characterized by a profuse thinning of the hair, often concentrated on the top side of the head.
This generally begins after the age of 50, but recently, cases of women as young as 20 or 30 are reporting progressive hair loss.
The hair growth cycle is regulated by the hormones produced in our body, and their imbalance is one of the main causes we see hair loss.
Testosterone is secreted in both men and women, but in woman’s body, androgens are converted into the female hormone, estrogen and thats the reason for low androgens levels.
Hair loss in women is sometimes triggered by a large decrease in estrogen, or when there is an excessive amount of testosterone.
Chronic and constant levels of stress, even low levels, are bad for our bodies, causing adrenal glands to sustain prolonged amounts of stress.
They then begin to make greater amounts of stress related hormones cortisol, and adrenaline which suppress DHEA, the main sex hormone.
This can trigger an increase in the conversion of Testosterone into DHT within the organs, and the hair follicles.
More DHT in the scalp leads to more sebum and smaller hair follicles.
It also contributes to poor blood circulation and a lack of nutritive elements that reach the capillary.
This is a big reason stress is a large factor in hair loss.
Don’t forget that it also strains the muscles in the head that contribute to the peripheral flow of blood.
The role of hormones in female pattern baldness
In females we can see that the hormonal imbalance can have a particularly devastating effect, because a lower DHEA secretion means lower feminine sex hormones.
The advantage is that women have hormones that act against androgens and continuously counterbalance their damaging effects.
This is why a lower DHEA secretion in a woman’s body is dangerous for the health of her hair.
Less female sex hormones, which are a derivative of DHEA, means that there is less protection against the aggressive androgen hormones like DHT.
Lower female hormone secretion means also an unbalanced sebum secretion, because the levels of the female hormones that protect the correct functioning of the sebaceous glands against the irritation that otherwise provoke the androgens, have dropped.
Imbalances in hormone levels are common during
- Puberty,
- Polycystic ovary syndrome,
- Pregnancy,
- Use of oral contraceptives,
- Menopause
- Natural low production of estrogens,
- Obesity and overweight.
