What Is Body Hair?
Quick Answer
Body hair is the hair that grows on different parts of your body besides your head. During puberty, new and thicker hair starts growing in places like your armpits, legs, and pubic area. Growing body hair is one of the first signs of puberty and is completely natural for both boys and girls.
Explaining By Age Group
Ages 3-5 Simple Explanation
You know how puppies have fur all over their bodies? People have hair on their bodies too! You already have tiny, soft hairs on your arms and legs. You might not even notice them because they are so small and light.
You know how grown-ups sometimes have hair on their arms or legs that you can really see? That hair grew as they got bigger. When kids grow up, their body hair gets a little thicker and darker in some spots. It is just part of growing.
You know how every animal has the right kind of covering for its body — like feathers on birds and scales on fish? Body hair is the covering that people have! It helps protect our skin and keeps us a little bit warmer.
You know how everyone looks a little bit different? Some people have more body hair and some people have less, and that is perfectly okay. Body hair is natural and nothing to worry about at all.
Ages 6-8 More Detail
Body hair is the hair that grows on parts of your body other than your head. You actually already have body hair right now — look closely at your arms and you will see tiny, light hairs. That type of thin hair covers a lot of your body and has been there since you were little.
When kids start going through puberty, something new happens. Thicker, darker hair begins to grow in places where it was not noticeable before. This usually starts in the pubic area and the armpits. It is one of the very first signs that puberty has begun.
Boys and girls both grow new body hair during puberty. Boys often grow more of it and may eventually grow hair on their face, chest, and belly. Girls also grow underarm and leg hair. The amount of body hair a person has depends a lot on their family and their background.
Body hair actually has a purpose! The hair in your armpits and pubic area helps reduce friction, which means it keeps your skin from getting irritated when you move. The fine hair on your arms can even help you sense things touching your skin, almost like tiny little feelers.
Some people choose to shave or remove their body hair when they are older, and some people choose to keep it. Both choices are fine. Body hair is a natural part of being human, and what you do with it is totally up to you and your family.
Ages 9-12 Full Explanation
Body hair is one of the earliest and most noticeable signs of puberty. While you have always had fine, light hair on your skin called vellus hair, puberty causes thicker, darker hair to start growing in new places. This usually begins in the pubic area and armpits, and it eventually spreads to other areas like the legs, arms, and sometimes the face and chest.
The reason body hair starts growing is because of hormones. When puberty begins, your body produces more of certain hormones that cause hair follicles in specific areas to produce thicker, coarser hair. This happens to both boys and girls, though boys typically end up with more body hair overall due to higher levels of certain hormones.
Body hair is not just there for no reason — it actually serves several purposes. Underarm and pubic hair helps reduce friction between skin surfaces, which prevents irritation. Body hair also plays a small role in regulating temperature and protecting sensitive areas of skin. The fine hair on your arms even helps your sense of touch by detecting light contact.
How much body hair you grow and where it shows up depends a lot on your genetics. If your parents or grandparents have a lot of body hair, you probably will too. People from different ethnic backgrounds tend to have different amounts and textures of body hair. There is a huge range of what is normal.
As you get older, you will notice that people make different choices about their body hair. Some people shave their legs or armpits, some people trim, and some people do not remove any body hair at all. There is no health reason you need to remove body hair — it is a personal choice. Whatever you decide is fine, and you should never feel pressured one way or the other.
If new body hair is making you feel awkward or self-conscious, know that what you are feeling is very common. Practically everyone goes through a phase of getting used to their changing body. Talking to a trusted adult about your options and your feelings can help you feel more comfortable.

Tips for Parents
Body hair can be a challenging topic to discuss with your child. Here are some practical tips to help guide the conversation:
DO: Follow your child's lead. Let them ask questions at their own pace rather than overwhelming them with information they haven't asked for yet. If they seem satisfied with a simple answer, that's okay — they'll come back with more questions when they're ready.
DO: Use honest, age-appropriate language. You don't need to share every detail, but avoid making up stories or deflecting. Kids can sense when you're being evasive, and honesty builds trust.
DO: Validate their feelings. Whatever emotion your child has in response to learning about body hair, acknowledge it. Say things like 'It makes sense that you'd feel that way' or 'That's a really good question.'
DON'T: Don't dismiss their curiosity. Responses like 'You're too young for that' or 'Don't worry about it' can make children feel like their questions are wrong or shameful. If you're not ready to answer, say 'That's an important question. Let me think about the best way to explain it, and we'll talk about it tonight.'
DO: Create an ongoing dialogue. One conversation usually isn't enough. Let your child know that they can always come back to you with more questions about body hair. This makes them more likely to come to you rather than seeking potentially unreliable sources.
Common Follow-Up Questions Kids Ask
After discussing body hair, your child might also ask:
When does body hair start growing during puberty?
Body hair is often one of the first signs of puberty. It usually begins growing in the pubic area first, followed by the armpits. For most kids this starts between ages 9 and 14, but the timing is different for everyone.
Is it normal to have more body hair than my friends?
Yes, it is completely normal. The amount of body hair a person has depends on genetics and ethnic background. Some people naturally have more body hair and some have less. Both are perfectly normal.
Do I need to shave my body hair?
No, you do not need to shave your body hair. Removing body hair is a personal choice, not a health requirement. If you are thinking about shaving, talk to a parent or guardian first so they can show you how to do it safely.
Why is my body hair a different color than the hair on my head?
It is very common for body hair to be a different shade than the hair on your head. The color of hair in different areas depends on the amount of pigment each hair follicle produces, and follicles in different parts of the body can produce different amounts.
Does body hair ever stop growing?
Body hair continues to grow throughout your life, but the amount and thickness often stabilize after puberty is complete. Some adults notice changes in body hair as they age, like growing less hair in some areas. It varies from person to person.
