The frequency of using an electric epilator depends on your hair growth rate and your personal preference.Generally,you can use an epilator as soon as your hair has grown to a length of 0.02 inches(0.5 millimeters),which is the minimum length that most epilators can pluck.This can take anywhere from a few days to a few weeks,depending on your hair type and the area you are epilating.Some people may prefer to wait longer until their hair is about 1/8 inch to 1/4 inch long,as this can make epilation easier and more effective.However,longer hair may also cause more pain and irritation when epilated.
The results of epilation can last up to 4 weeks,as the hair is removed from the root.Some epilator brands even claim that one application lasts up to six weeks.However,this may vary depending on your hair growth cycle and how often you epilate.The more you epilate,the slower and finer your hair may grow back,which means you may need to epilate less frequently over time.
To sum up,you should use an electric epilator when your hair is long enough for the device to grip it,but not too long that it causes more discomfort.You should also use it as often as you need to maintain smooth and hair-free skin,which may vary from person to person.The best way to find out what works for you is to experiment with different lengths and intervals and see how your skin reacts.
