wax , or there are fantastic shavers you can get from shaving shops especially for down there , first you trim with a wand type thingy and then go over it with what look like a lint remover .... HONESTLY there is no ingrowns and no regrowth for about 1 week ..

i bought one when pg with ds ... i use it all the time and its so smooth , just like a wax ... only near then end i got dh to shave the bits i couldnt see ... .
