Detailed explanation-1: -Is armpit hair the same as pubic hair? Facial hair, armpit hair, and pubic hair are all the same type of hair, called “terminal hair.” It starts growing as fine hair (vellus hair), and at puberty starts to change and progresses to a coarse hair.

Detailed explanation-2: -Yes. In girls, breasts develop first. Then, hair starts growing in the pubic area. Next, hair starts growing in the armpits.

Detailed explanation-3: -For most girls, armpit hair starts to grow a little while after they get pubic hair. So, if you have some pubic hair (even if it’s scanty and soft) and you have your period, armpit hair may still be on its way. Then again, you may never have much armpit hair (and that’s not a bad thing).

Detailed explanation-4: -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.
