At around 12 years old, on average, females will begin to see hair growth under the arms. Pubic hair will start growing along the labia and will gradually become thicker, curlier, and cover a larger area of the vulva.
Adrenarche is usually normal in girls who are at least 8 years old, and boys who are at least 9 years old. Even when pubic and underarm hair appear in children younger than this, it is still usually nothing to worry about, but your child does need to see their pediatrician for an exam.
Everyone has pubic hair, but we all make different decisions as to what we do with it. Some people prefer to let it grow, while others trim it, shave it, or wax it. What you do with yours is up to you.
Many tweens and teens want to shave, and there are no health reasons for them to wait. It's reasonable to allow them to shave when they think they're ready to do so. On the other hand, some tweens and teens will not be interested in shaving at all, and that is fine.
Premature pubarche, or the development of pubic hair before the age of 8 in girls or 9 in boys, is most commonly caused by premature adrenarche. Adrenarche is the maturation of the adrenal zona reticularis in both boys and girls, resulting in the development of pubic hair, axillary hair, and adult apocrine body odor.
It's not uncommon for young children to show certain traits associated with puberty, including some pubic hair, underarm hair and the beginnings of breast development, said Dr. Paul Kaplowitz, who led the American Academy of Pediatrics report.
Higher total protein, animal protein and meat intake in children ages 3 to 7 have been associated with earlier onset of menstruation. High protein intake elevates IGF-1 levels and promotes growth, which could accelerate the onset of puberty.
Protection from bacteria and other pathogens
It follows that pubic hair may protect against certain infections, including: cellulitis. sexually transmitted infections (STIs) urinary tract infections (UTIs)
According to board-certified obstetrician and gynecologist Dr. Felice Gersh, MD, there is a “basic normal amount” of female pubic hair. She explains, "Typically it should cover all of the labia majora to the inner surface of the thighs and up to the pubic bone-roughly shaped like a triangle."
Everyone has some hair in the area between their butt crack. This hair wicks away moisture and protects the sensitive skin around your anus.
12. Your pubic hair won't keep growing forever to endless lengths. Some people are blessed with Rapunzel-like locks or thick man buns adorning their scalps, but pubes don't grow that long. The fur on our fun bits has a shorter growth cycle, lasting a matter of weeks.
Part of the perception that your pubic hair grows much faster than the hair on your head may be due to the growth cycle it follows. With pubic hair—and other body hair—the entire process takes about 30 to 44 days, Dr. Hazen says.
Legs: shave lightly from the ankles up. Underarms: shave in all directions your hair grows. Bikini Area: shave in the direction of the hair growth first; then you can go against the grain for a closer shave.
It's Not About Age, It's About Your Child
Most sources suggest that the longer your daughter can wait before starting to shave, the better. There's no "magical" age that girls should start shaving, but the general consensus is that most girls start at some point between the ages of 11 and 14.
Bacteria can cling to hair. In the vaginal area, that is both a good thing and a bad thing. You need your good vaginal bacteria to prevent an overgrowth of yeast, but when bacteria mix with the sweat and oil on your pubic hair, it can produce a smell.
African-American and Hispanic girls tend to reach puberty earlier than their white counterparts, research shows.
The average age for girls to start puberty is 11, while for boys the average age is 12. But it's perfectly normal for puberty to begin at any point between the ages of 8 and 13 in girls and 9 and 14 in boys.
