For limited areas of alopecia, the affected hairs shed and new hair may regrow. No treatment is usually needed because 95 percent of the time the hair will regrow.
Your doctor may prescribe a few medications to try to help the hair to grow. However, there is no good evidence that any of these treatments will guarantee the hair will regrow. These may include:
- Steroid cream, ointment or solution that is put on the skin where hair loss has occurred
- Another type of medicine put on the skin, called topical calcineurin inhibitors (Elidel cream, protopic ointment)
- A form of vitamin A that is put on the skin (topical retinoid)
- Steroid injections
Follow the instructions for use very carefully. If the skin gets irritated, or if you have any questions, call your doctor.
There is little evidence that use of oral medicines will produce lasting hair regrowth, and the side effects of these medicines usually outweigh any potential benefit.
