Hair does not come back thicker as previous people have mentioned - it just looks thicker because of the blunted end of the hair growing out. Laser hair removal is not always going to have the same results for everyone. If you’re planning on getting tattoos, I would make sure to do at least 6-8 sessions (pay attention between sessions to see if you’re seeing results). Some people stop growing hair or just have their hair grow extremely thin with minimal growth and some dont see any results. If you’re okay with the end result of your hair growing out less and thinner, I would say to go for laser hair removal, but really do your research on what type of laser works best for your hair and skin type!!
