there is electrolysis..

which is laser hair removal, and it's supposed to make the hair not return very soon..

Thing is is that it's sort of expensive and you have to do it like 4 or 5 times because your hair grows in cycles.. So the first cycle grows, you have it removed, but the first cycle is completely different than the others, so when the second grows you have to get that removed, and so on..

at least this is how i understand it..
