I am a boy and my hair by the corners of my head in the front is receding. What should I do?

Do you have male relatives - father, grandfathers who are bald? If so, there's nothing much you can do - unfortunately, some men/boys start having receding hairlines, even as youngsters. There are medications you can take to slow down the process, but they can have side effects, and aren't recommended for teens. You could also visit a doctor to discuss the issue - occasionally, there are hormone imbalances that cause balding, and if you want treatment, you need to see a doctor anyways. In the meantime, experiment with different hairstyles (possibly a shaved head) - and don't let your hair affect your self-esteem. Most men will lose hair sooner or later anyways!
