Hi there, I was just wanting some advice for hot waxing underarms that are very fine hair?? It just seems that hot wax simply doesn't work as well as strip wax for fine hair, but I realise that it's gentler and most clients probably prefer it, but I just can't seem to perfect my technique. (Too many hairs left, sometimes hardly any come out and don't want to have to go over it 4 times!) Any advice would be much appreciated, ie: apply with or against hair growth direction? Powder or oil beforehand or both? Etc.
