Hi, my daughter is 9. she has hair in her underarm. is the good idea to do wax or it's too ?

Leave it alone: I would not subject your daughter to waxing at her age. I would let it be until she is old enough to handle a razor safely. Take Care!

Time for a talk: As a kid transitions into puberty it is a good time to help them start making decisions about personal care.Its also a good time to review what will be happening to her body to show you are receptive to discussions on these issues. A depilatory like Nair or other forms of hair removal should be discussed and she should be given a chance to decide when/how to proceed.
