Is there something wrong if you dont have armpit hair and already went through puberty long time ago but still it is girl?

It is normal for some women to have little or no armpit hair. There is no one "right" amount of armpit hair, and it can vary greatly from person to person. Some women have a lot, some have a little, and some have none at all. This can be due to a number of factors, including genetics, hormones, and age.

Lack of armpit hair may be a result of genetics. Just like some people have more or less hair on their head, some people have more or less hair in their armpits. Another reason for having less than normal armpit hair is hormonal imbalances. The hormones estrogen and progesterone, which are produced by the ovaries, help to stimulate hair growth. If a woman does not produce enough of these hormones, she may have less armpit hair than normal.

Age can also be a factor in armpit hair growth. As women age, they may produce less of the hormones that stimulate hair growth. This can lead to a gradual thinning of the armpit hair.

If you are concerned about your lack of armpit hair, you can talk to your doctor. They can rule out any underlying medical conditions and help you to feel more confident about your body.
