Creams
Hair removal creams give much the same results as shaving, in that they really only remove the hair at the skins surface and hence grow back is quicker and stubbier initially. Hair removal creams work by dissolving the hair usually using an alkaline substance. Some creams have growth inhibitors which are supposed to slow down the hair grow back speed.
Electrolysis
Electrolysis is the slowest but potentially the most permanent hair removal method when performed by a skilled practitioner. Electrolysis involves inserting a tiny thin metal probe into hair follicles. Electricity is passed into the follicle through the probe, which then damages the hair growth area. Electrolysis has the advantage of being safe and very effective, but it is very slow to perform and thus not particularly well suited to large areas from a cost point of view.
