I have dark hair with light skin. Removed >80% of hair on body 3 years ago with laser, cleared the rest of those areas with electrolysis. But I found laser just wasn't effective for face or genital area - ended up using thermo electrolysis, very close to 100% now.
My electrologist has 25+ years experience, she doesn't worry about competition (her schedule is fully booked, and she referred me to a laser specialist for initial genital hair removal). The pattern she has seen with several genetic-male clients: 1 to 2 years after laser, patches of thin dark hair sometimes appear on face and neck - slightly thicker than velus hair but noticeable enough these need removal and it can be frustrating to have these patches appear out of nowhere on an otherwise clear face. With electrolysis, once hair is gone it really is gone - I've seen this myself.
Something to consider: MTF hormone replacement therapy is known to stop and reverse hair growth on the body but not facial hair. That's because post-puberty facial hair on a genetic male is a different type of root. This difference also impacts the effectiveness of various hair removal methods.
Same with genital area - expensive laser work thinned my hair down there, many of the remaining individual hairs were thinner diameter but still there. I've used 3 types of laser including YAG where the skin is darker. Now I'm having that same area taken care of with electrolysis - all that laser work downstairs had weak results.
Every body is different, but if I started over - I'd use 100% electrolysis for face & genitals, laser everywhere else. Electrolysis requires time and pain, but the results are soooo worth it!
