I go through phases regards waxing/shaving. At the min, I am shaving my legs and underarms and waxing my bikini line. I am immensely prone to ingrown hairs, even though I am religious where exfoliation (both manual and chemical) and moisturisation are involved, and use PFB Vanish (wonder product, minimalises ingrown hairs on myself, but doesn't eradicate them completely).
Professionally, I am not a full-time waxer, I used to be (virtually!), but now I just wax friends and family, and a couple of client appointments per week when our other beauty therapist is double booked. When I discuss different types of hair removal with clients, I never look down my nose on other types of hair removal. Each type has its positive and negative aspects, its pros and cons if you like. I, personally, deem it as unprofessional to tell a client they shouldn't shave, as though it's not the 'done thing'. I'm making money from waxing, so if I start acting as though any other type of hair removal is a shoddy second best, it's going to be pretty obvious why I'm doing it! And, anyway, I actually believe shaving is the best type of hair removal for me, and that waxing is the best type of hair removal for my friend (one of those that I wax), as she never gets ingrown hairs, and she remains totally hairless for a minimum of four weeks (I suffer the beginnings of regrowth after one week). So it is clear that different types of hair removal are best for different people.
I don't believe clients should be cajoled into thinking that waxing is the holy grail, as I have seen so many therapists do. We will earn our clients' respect if we are honest and give an unbiased review of the different methods of hair removal and their benefits and downfalls, and their suitability for the individual.
