How many times does it take?

One thing i don’t understand is if you have to do it more then one time for one hair. One you stick the needle in and do it right, do you have to do it again? Or is it just once?

If you do it right, and at the correct time of the year, you only need to treat a single hair ONCE. Since your have lots of hairs that are not on the same growth schedule, you need to do one area many times to get the desired result.
