The time to recover from baldness varies greatly from person to person. Patients with mild disease may heal themselves within 3 months, while those with severe disease may not heal for a long time. This gap is determined by a variety of factors, including genetic factors, psychosomatic factors, immune status, and treatment options. Some types of baldness can see new hair within half a month of effective treatment, but most patients generally see results in about 1-3 months of effective treatment and are cured in 6-24 months. The new hair is relatively fine, white and sometimes curly, which is a normal state of recovery and not a bad quality of hair or malnutrition. Hair loss stops and this white hair grows on the hair loss spot, which is an indication that the treatment is effective; at this time, patients should not think that they are cured and stop the medication on their own, but should continue to consolidate the effect. If black spots can be seen in the new hair, or hair stubble, it means that the disease is not yet stable, reduce or stop the drug may relapse. Therefore, the reduction or discontinuation of medication must be done under the guidance of a doctor. Generally, doctors will ask patients to wait until the hair is in a healthy state before reducing the dosage, and not to rush. If no results are seen in three months, the current treatment plan is not suitable and the medication needs to be adjusted or the underlying cause of the baldness needs to be further investigated. Some patients have not regrown their hair for many years, then a scalp biopsy is needed before treatment to observe the number and status of the hair follicles under a microscope and to assess the significance of treatment. This is because some hair follicles will gradually degenerate over time in baldness, resulting in a failure to regrow hair in that area. The timing of follow-up visits for patients with baldness likewise varies from person to person. Patients who are treated with only topical medications are generally slow to take effect but have few side effects. If there are no skin allergies, a visit to the hospital once every two or three months is sufficient; however, patients who are taking oral hormones or cyclosporine should be reviewed once every half a month to once a month – patients taking hormones should pay attention to electrolyte concentrations and whether their blood sugar and blood pressure are normal, while patients taking cyclosporine should pay attention to blood pressure and blood potassium, and check blood concentration regularly to avoid side effects caused by taking the medicine.
