Excessive androgens may lead to androgenetic alopecia, in which patients experience progressive hair loss. Hair loss, mainly divided into physiological alopecia and pathological alopecia. Physiological alopecia includes natural hair loss, infantile alopecia, senile alopecia, post-partum alopecia, etc. New hair will continue to grow out, and generally do not need special treatment. Pathological alopecia, including hair loss caused by bacterial and fungal infections, endocrine diseases, immune system diseases, nutrient deficiencies, trauma, androgenetic alopecia, and so on. Hair loss caused by hyperandrogenism, also called premature baldness, is usually accompanied by seborrhea in patients, also called seborrheic alopecia. The patient’s hair has increased sensitivity to the effects of androgen biology, and is affected by the androgen levels, the hair follicles shrink and become smaller, and the hairs gradually fall out. Therefore, high androgen levels may lead to thinning of the hair, an increase in the percentage of fine hair, and a progressive loss of hair volume. To summarize, hair loss is related to a variety of factors. If it is caused by physiological factors, no special treatment is usually needed. If you suspect that hair loss is caused by pathological factors, it is recommended that you go to the hospital to find the cause and actively treat it.
