Try Sugaring I am qualified at it. It is less painful, breaks less hairs and actually deminishes the hair growth. Legs I find the most painful, but I do suffer myself with very sensitive skin. The other thing is to take some paracetomol before going which will take the edge of the pain.
Also you are more suseptable to ingrown hairs as the hairs are more puny after waxing/Sugaring so use Tea Tree Oil to prevent this, this will disolve any dead skin over a hair and stop red boils from developing as it is an anticeptic (not to use if you are pregnant though) and ALWAYS MOISTURISE this will stop your next treatment from being so painful as you will not pull the skin as well as hairs.
And finally the therapist should use talc as this stops the product pulling at your skin and only your hairs.
Good luck......
