Hey hun,
This is my area of expertise thanks to being a head therapist at Strip waxing boutique in London
All the other geeks have given you great advice but I thought I would share my tips anyway!
Firstly always be prepared for the unprepared or unusual clients! I have experinced all sorts and doing male intimate waxing aswell lets just say men are not the cleanest of creatures
Secondly NEVER use strip wax on an intimate area... or any sensitive area really. Strip wax will not give you a clean finish if you have a client with excessive or strong hair growth (post shavers/polycystic ovary clients etc.) It just breaks the hair or gets stuck and very messy
also it hurts a hell of lot more than hot wax.
Thirdly once you have the hang of hot wax dont be afraid to get in there, always have one hand gloved (the hand you press with) and use this as your stretching hand. Good firm stretches show the client your confident and keeps them comfortable. With regard to asking the client to stretch upwards, I highly recommend it once the wax is on and set of course
The better the stretch the less pain!!
And lastly always trim the hair if it is to long to avoid tangling!!
Hope that helps
