Is there an age limit to waxing? Not really. Yesterday I waxed 3 separate 13 year old girls. The first one had very dark hair on her upper lip & a connected brow. The second girl had a lot of hair that poked out of her bathing suit and the third one had very dense bikini hair that was noticeable beneath her bathing suit. All of them told me they were embarrassed by their hair and two of them even tried shaving. Both of those girls told me that their skin got very irritated by the razor and they swore they'd never shave again. Ironically the girls that got the bikini waxes tolerated the wax better than their mom's. 😁
