Severe generalized baldness can be oral glucocorticoids, cyclosporine, etc. Mild patch-type baldness can be used externally with 5% minoxidil cream, etc., and local injections can also be applied. 1. Glucocorticoid: short-term severe alopecia, short-term oral prednisone tablets, glucocorticoid effect is good, but the side effects are big, easy to relapse after stopping the drug, so it is not as a routine therapy. But for acute baldness, in order to avoid the development of total baldness or universal baldness can be tried. 2. Cyclosporine: patients with serious condition and recurrent episodes, when glucocorticosteroids are ineffective, cyclosporine can be used, which is effective in some cases, such as discontinuing the drug after 4 months without effect. 3. Topical drugs: 5% minoxidil cream or solvent, 0.5% ~ 1% anthralin ointment or cream for external use, the application of strong hormone sealing can often play a very good effect, such as 0.05% dexamethasone, 50% dimethyl sulfoxide solution sealing. 4. Local injection of glucocorticoids: applicable to a smaller range of alopecia, or general baldness patients with important cosmetic parts (such as eyebrows). It can be injected directly into the alopecia area, or into its peripheral part, with a view to controlling the continued expansion of the scope of alopecia. Care should be taken to avoid localized skin atrophy and indentation that may be caused. Commonly used preparations include prednisolone suspension and Depo-Provera injection. Most common baldness has a tendency to heal naturally, a few cases occur repeatedly, so the treatment is difficult. If you suffer from baldness, it is recommended that you consult a doctor as soon as possible, and treat it under the guidance of a physician, rather than blindly self-medicating.
