The question of why is my hairline receding is one that can be difficult to answer. However, there are some things you can do to help it. First, you should know that receding hairlines are not always a sign of a health problem. This problem is mostly due to genetics. A simple scalp brushing and OTC treatments are often enough to help the condition. If you haven’t experienced receding in a while, see a dermatologist or trichologist.
