Definition
Every single hair is associated with a sebaceous gland. This produces a small amount of secretion that keeps hair and scalp supple. It serves to protect against infections, as pathogens can easily penetrate the body through dry skin.
When the sebaceous glands secrete an excessive amount of secretion, the greasy film lies on the hair, sticking to it and making it look stringy. The male and female sex hormones influence the sebaceous glands. Androgens, the male sex hormones, increase the growth rate and secretion production of sebaceous glands.
Estrogens, as representatives of the female sex hormones, have an opposite effect to the androgens. Particularly during puberty, when there are changes in the hormone cycle, imbalances can occur which lead to oily hair. Only in rare cases is there an underlying cause requiring treatment.
One example is the polycystic ovarian syndrome. Typically, bleeding disorders or an unfulfilled desire to have a child, as well as pain in the lower abdomen, are the focus of attention here. Accompanying “masculinization” as well as oily hair is observed.
Another hormone that influences the appearance of the hair is cortisol, which is produced by the adrenal gland. Cortisol is a vital stress hormone that keeps the metabolism in balance. In higher doses, it also has anti-inflammatory and immunosuppressive effects, which is why it is so important in the treatment of cancer or autoimmune diseases, for example. In addition to the positive effects, however, there are also negative effects if a larger quantity than necessary is produced or long-term therapy with cortisone in tablet form is required. In addition to oily hair and skin, more common complications include osteoporosis, diabetes, fat redistribution from the extremities to the trunk, full moon face, water retention and a disturbed menstrual cycle.
Symptoms
In addition to increased oily hair, an increased testosterone level in women can lead to “masculinization”. *This includes increased hair growth, which can also manifest itself in the form of beard growth (so-called hirsutism). The body can become more muscular and the voice deeper.
Skin problems often appear as acne. In serious cases, the menstrual cycle and thus the fertility of the woman is disturbed. Insulin resistance can also be observed. This means that the body can no longer absorb its fuel, sugar, well into the cells. Type 2 diabetes mellitus develops.
