Androgenetic alopecia and seborrheic alopecia are the same disease and there is no need to make a distinction.
Seborrheic alopecia, or androgenic alopecia, is related to heredity and androgens. Androgens in the body will be converted by reductase enzyme into dihydrotestosterone, an important molecule leading to androgenic alopecia, which will miniaturize the hair follicles, make the hair in the anagen phase gradually become thinner, shorten the growth cycle of the hairs, and finally lead to the disappearance of the hair follicles and the loss of the hairs.
Seborrheic alopecia mostly develops after puberty. In men, the main manifestation is that the hair on both sides of the forehead starts to become thin and sparse, and then slowly extends to the top of the head, with the frontal hairline receding backward. In women, the symptoms are usually milder, with the main manifestation being the gradual sparseness of hair at the top of the head, and the change of the frontal hairline is usually not obvious.
If you have seborrheic alopecia, you need to go to the hospital as soon as possible, and the doctor will formulate an individualized treatment plan according to your specific condition, so as not to delay your condition.
