No treatment for active telogen effluvium has been proven effective.
Some causes of the disorder can be corrected. For example, if you have a poor diet, consult a dietitian to help you balance it. If the hair loss began after you started a new medication, talk to your doctor to see if the medication should be discontinued. Many times, however, the cause is a specific event in the past, and you can expect that the hair will grow back. In cases where hair growth has not returned to a satisfactory level, your doctor may prescribe minoxidil (Rogaine), a lotion applied to the scalp that may stimulate hair growth in some people.
