I found a petua sumwhere;
mix a bit of kapur (the one that ppl eat with sirih) with some lime juice. usually i just use calamansi lime. easy to obtain. spread the mixture at underarm. wait a few seconds/minutes and then the armpit hair can be plucked using fingers. no need for tweezer! seriously, and it doesn't hurt at all. my armpit now less dark than before also.
Happy trying!
What is the BEST way to remove armpit hair?
