Hi all! I'm new to waxing and only trained a few weeks ago in hot wax. I have done a few upper lip waxes now and I now have a lady enquiring about having her upper lip waxed but she currently shaves every 2 days. What length of growth should she have for me to wax? I know it would make a huge difference for her to have her lip waxed rather than shaving every other day. I'm not sure how long she will be able to go without shaving beforehand as she says she has quite a dark growth. Any help or advice will be greatly appreciated! xx
