Boys start to grow more hair on their cheeks, chin and neck. At first the hair is fluffy and light but over time it gets longer, darker and thicker. It might not fully develop until he is in his late 20s.
Some boys end up with thick facial hair, but others will have lighter or patchy facial hair all their lives.
To remove facial hair boys can use razors or electric shavers. Ask a parent or trusted adult to show you how to start shaving.
