Seborrheic alopecia, also known as androgenetic baldness and premature baldness, is a disease characterized by progressive reduction of hair on the top of the head and is commonly seen in young men. In men, the cause of seborrheic alopecia is mainly related to excessive secretion of androgens by the testes, while in women, it may be due to endocrine disorders caused by the adrenal cortex and ovarian hyperfunction, which in turn cause excessive secretion of androgens. Seborrheic alopecia is genetically predisposed, but its later appearance is mainly related to androgens. The increased secretion of androgens in the body will cause an increase in the synthesis of dihydrotestosterone, which, when combined with the receptors of hair follicle cells, will lead to shrinkage or even atrophy of hair follicles, thus making the hair in the anagen phase thinner and softer, and some patients may also form Mediterranean-like hairstyles. In addition, mental factors, poor dietary habits, irregular work and rest, and local infections can also trigger seborrheic alopecia, and can lead to aggravation of the disease. Seborrheic alopecia is a progressive exacerbation disease, and clinical treatment is mainly based on medication. Male patients can take oral finasteride and other drugs as instructed, and female patients can take spironolactone and other drugs as instructed. These drugs can reduce the symptoms of hair loss by inhibiting the synthesis of dihydrotestosterone, but it takes a long time for the drug to take effect, so patients need to continue to use the drug. In addition, topical peripheral vasodilators such as minoxidil can improve local microcirculation and also promote hair growth. Patients who have not been treated with medication can also undergo hair transplantation, but the survival rate of hair follicles after hair transplantation is highly variable and expensive on an individual basis. If you choose to have a hair transplant after extremely strong will and careful consideration, you can go to a hospital or professional institution.
