Heres a question that we here very often:
Can all the hair be removed in one session of electrolysis?
A) No, generally there may be more hair than a client is able to sit for (e.g. more hair than is able to be treated in one session) or there are hairs underneath the skin that have not grown through yet.
Saying that, if there is a little collection then we may be able to remove all this hair in one appointment!
But does this mean it will be gone for good?!
Hair needs to be treated more than once for it to die (2-4 treatments, more if on a very low current) and it must be treated consecutively, 6 weeks apart. You can treat hair 20 times once a year and it will not die, why? Because its not in the anagen stage of growth. This stage (4weeks after a wax or 6 weeks after electrolysis) the follicle is very juicy and we turn all that juice into sodium hydroxide which detaches the hair. No juicy follicle means its not worth treating! Or atleast it will not be dead, you may not notice it is gone for a few months but it is not dead and will develop again with any hormonal changes or stress changes.
