Nowadays, the trend of hair loss is getting more and more obvious, and men between 20-40 years old have become the main force of hair loss, of which male pattern baldness is the most common type of hair loss, accounting for more than 95% of all male hair loss patients, and the treatment of hair loss situation has become urgent. The first task is to understand where the “disease” lies. The cause of male pattern baldness is mainly related to two factors: hair follicles and dihydrotestosterone. Dihydrotestosterone is a product of androgen metabolism referred to as DHT, which is distributed throughout the body through blood circulation, and some people’s scalp hair follicles are very sensitive to dihydrotestosterone, so that dihydrotestosterone will make the hair follicles enter the regressive phase from the anagen phase and eventually make the hair follicles completely apoptotic necrosis, resulting in hair loss. When we know the principle and then choose the treatment method becomes evidence-based, now look at some folk widely circulated treatment for hair loss can know whether it has scientific justification, such as ginger for hair loss this prescription says: “ginger contains ginger spice, ginger oil and other ingredients to normalize blood circulation in the head, promote metabolism to treat hair loss “, but the patient’s own head blood circulation and metabolism itself is not a problem, ginger has no effect on the fundamental factors in the dihydrotestosterone, so similar to ginger for hair loss folk remedies for hair growth we should not be gullible, must adhere to the scientific treatment methods. How to carry out scientific treatment? Scientific treatment needs to be provided by qualified medical institutions and doctors with professional knowledge, so when symptoms of hair loss appear, you should go to a tertiary care hospital with a special clinic for male pattern baldness (AGA special clinic) for diagnosis as soon as possible. Regarding scientific medication, among the two drugs that have been proven to be effective in treating male pattern baldness through rigorous clinical trials, finasteride is the only drug that treats hair loss by blocking the conversion of testosterone to dihydrotestosterone and reducing the content of dihydrotestosterone in the blood vessels of scalp hair follicles, and is therefore widely used in the treatment of male pattern baldness. Currently, oral finasteride is the most important treatment for male pattern baldness, and the patient’s medication needs to be scientifically guided by the doctor at different stages. In addition to scientific and objective treatment, patients also need to establish a scientific mindset for healing, to build self-confidence, avoid fear, learn to shift goals and take the initiative to reduce stress. On this basis, as long as people can adhere to the scientific treatment, I believe they will achieve good treatment results.
