Brittle, falling out hair is a problem for most modern women. This problem is related to ecology, poor nutrition and hormonal imbalance. To find its cause, you need to determine the concentration of hormones in the blood.
The health and appearance of women’s hair depends on the following hormones:
1. Estradiol is the main female hormone produced by the ovaries (female sex hormones are also called estrogens). Thanks to estradiol, woman’s hair looks much more magnificent than man's.
2. Somatotropin is a hormone produced by the thyroid gland. This substance promotes the restoration of hair follicles and determines hair color.
3. Thyroid-stimulating hormone, also produced by the thyroid gland. This biologically active substance affects the strength of the hair shaft.
4. Melatonin produced by the epiphysis.
5. Progesterone is another female sex hormone produced in the ovaries.
The positive effect of the above hair growth hormones is observed only at normal concentrations in the blood. If there are problems with the work of the endocrine glands, these same hormones can cause hair loss. For example, a lack of thyroid-stimulating hormone leads to hair fragility and lifelessness.
