This is discussed by sex below. Male Most questions I get from men are about back and chest hair. I usually recommend waxing as the safest option. Although electrolysis can be a good option for those with sparse hair, most men find this method to be painful, expensive, and time-consuming for large areas. Shaving is by far the most popular option.
Electrolysis can be permanent, but it requires a serious commitment of time and money.
Beard removal is possible with electrolysis, but it will take a very long time and must be done by someone with a lot of experience. The heavier the beard, the more likely you are to get scarred, so it's very important to choose an electrologist recommended by someone who had male facial hair removed and is done and happy. Some with light skin and dark hair have found laser useful, but there is limited data on how long it will last and how often treatment is successful. There are early indications that super-long pulse lasers might be an acceptable alternative to shaving for black males, but it's too soon to tell for sure. Laser can sometimes lighten the color of facial hair and reduce the amount of shadow, but some have reported patchy or grid-like regrowth that looked odd.
