Girls will begin to grow hair under their arms and on their vulva, and the hair on their legs will become thicker and darker. Boys will begin to grow hair under their arms, around their penis and testes and on their face. Some boys will also grow hair on their chest and back.
Hair growth is a normal part of growing up. Keeping or removing hair is a personal choice, and you can support your child to make their own decision about what to do with the new hair growth.
