The most common cause of baldness is mental stress, so in most cases patients can heal themselves by adjusting their mood, living a regular life, paying attention to rest and allowing their immune function to return to normal; if the area of hair loss is large and progresses quickly, hormone therapy can also be applied in combination with the patient’s psychological state. The hormone referred to here is cortisol hormone, which belongs to a kind of immunosuppressant, can reduce the inflammation around the hair follicle, inhibit the development of the disease, promote the recovery of the function of the hair follicle, and make the hair regenerate; the growth of hair will also have obvious relief of the psychological stress caused by hair loss, which is also beneficial to the treatment of baldness, thus entering the virtuous cycle of disease treatment. There are two types of hormone therapy, systemic and topical. Systemic hormone use includes oral and injections, which can regulate the immune status of the whole body, and is usually used when baldness is developing rapidly or the area of hair loss is large. Since systemic hormone use has certain side effects, such as fattening, hairiness, etc., the duration and dosage of the medication need to be regulated by an experienced doctor according to the condition, and cannot be used for a long time on your own. If you are unwilling or intolerant to hormones, you can also switch to cyclosporine, which is another immunosuppressant commonly used to treat baldness. Topical hormones are generally strong hormones that are effective in promoting hair regrowth. The most common side effects are capillary dilation, skin atrophy, skin erythema and, in some younger patients, folliculitis. However, all these side effects can gradually subside after stopping the drug. Other than this, topical hormones rarely have other side effects, so do not reject them when you hear “hormones”. It should be noted that while applying hormones to treat baldness, it is important to “treat the root cause”. If the immune status is not regulated properly, baldness can easily recur after stopping the medication. Therefore, patients should adjust their psychological state and live a regular life. If there are other underlying diseases, such as Hashimoto’s thyroiditis, active treatment is also necessary to help reduce the recurrence of baldness. Some stimulating medications can also treat baldness, such as capsaicin ointment, anthralin ointment, etc. These preparations stimulate a mild inflammatory response in the scalp, which encourages hair regrowth. The folklore of applying ginger to the scalp is often said to be based on the same principle. However, its efficacy is limited and is used less frequently.
