Laser don't exactly remove hair, it's like rewind the clock of your hair to a pre-puberty state, only that if you are a grown up man the development of your body is now complete and so the hair will not regrow as before (but will slighty). You will continue to grow hair with the time (during the treatment the bulb will be too stressed so you will not notice it) but they will be the same of the kids, very weak and almost invisible.
I'm doing it on front and back because they really have an awful shape (unlike many I saw) and I have often itching.
I have to do at least 18 seance, 1 per month, then afterwards there is 1 annual seance to keep killing the few bulb that continue to resist.
For both I payed about 1500 €, but I did it because I work and I can efford it. I never tought about doing it before having an income.
Sorry for my english, I'm Italian too…
