If temporary methods of hair removal aren't doing it for you, and you want to get rid of that back hair sticking out from the neck of your T-shirt for good, electrolysis may be a good option. This technique uses a thin metal needle to get to the base of the hair follicle, where it's zapped with an electric current. This effectively cauterizes the hair follicle and prevents future hair growth, if it's performed correctly. The downside is that it can be expensive if you have a large area to cover, and there can be some pain involved. And since each hair is zapped individually, it's fairly time consuming as well. On the plus side, it's been getting proven results since 1875 when it was first performed by Dr. Charles E. Michel to remove ingrown eyelashes [source: Richards]. Just make sure you find an experienced and reputable technician so you can achieve the desired result.
