The reason for eyebrow hair loss will significantly influence treatment options. Eyebrow hair can become thin or brittle due to stress, genetics, age, and burns or other injuries. The side effects of some medications can also influence the fullness of the brow. You’ll need to work with your doctor to determine the exact cause of your hair loss before you settle on an eyebrow restoration plan. When you’ve determined that an eyebrow transplant is the right course of action, the Brow Regenesis™ eyebrow restoration procedure is simple, nearly painless, and can be completed in a single day.
