Thanks for all the great information. I've been looking to do some electolysis. I've got dark, coarse and have done all my life. I'm perfectly happy shaving with a razor, but I'm discovering as I get older that there are some particularly coarse hairs that have a tendency to become ingrown. It's causing scarring, so electrolysis seemed like a good option. Professional electrolysis for a dozen problem hairs seems unnecessary. Your site has been a great resource in helping me find out what I need to know about home electrolysis!
