What causes seborrheic alopecia

summary

When I go to the hospital, I don't know what causes alopecia. I don't know what causes alopecia when I'm young.

What causes seborrheic alopecia

The first is genetic factor (30%): the cause of premature alopecia is unknown, but the patient often has a clear family history. The earliest detectable change is the degeneration of the lower part of the hair sheath in the connective tissue of the hair follicle, accompanied by basophilic changes around the blood vessels. The hair follicles gradually atrophied and became smaller, and finally were replaced by trichomes. Finally, many trichomes and hair follicles disappeared, leaving a bundle of sclerotic glass fiber like connective tissue. This can lead to hair loss.

The second is high androgen (25%): there is enough androgen in the blood is often an important factor in the occurrence and development of alopecia. Men do not have early alopecia before puberty, but long-term treatment with testosterone can lead to hair loss. Hair loss increases with age, and the beard, pubic hair and armpit hair do not fall off. It is found that 5-a-dihydrotestosterone accumulates in the hair follicles involved in the early stage, which may inhibit the metabolism of hair follicles. So we should treat it in time.

The third is other factors (20%): local factors such as too tight hat, wearing pressure hat at night, washing hair with too cold (or too hot) water are not the main factors. However, it may also cause seborrheic alopecia.
