Alopecia areata occurs when the immune system attacks hair follicles, where hair growth begins. Because hair often grows back within a year, you may decide not to have treatment. Understanding the come-and-go nature of hair loss with this condition can help you make the best treatment decision. Children and teens may need counseling to help them adjust to the hair loss.

Success of treatment
How successful your treatment is depends on your expectations and the cause of hair loss. Treatment for hair loss caused by an illness, medicine, or damage to the hair usually is more successful than treatment for inherited hair loss.
