Girls always itch under their armpits. Do they want to have long hair?

The armpit is always itchy, which may be caused by local eczema and hair follicle infection. Generally, it is caused by unclean skin or decreased body resistance, and has nothing to do with the length of armpit hair. Pay more attention to rest and personal hygiene, take more vitamins, eat less spicy food, apply Pampers and Piyanping when necessary, and it will get better gradually.
