Scrub first before you are using an epilator. This will prevent ingrown hairs.
Take a cotton thread (sewing thread) of about 30 centimeters. Take the two ends fixed to each other by means of a button. Put the wire around the index finger and thumb of one hand and thread with the other hand the wire about 5 times around so you're in the middle have a spun piece of wire. Now do well to your other index finger and thumb wire. Go to where you want to lose hairs and open one hand, while closing the other. This allows the center to rotate and pull the hair out. Works every time!
