I had my first last hair removal appointment a week ago on my bikini area. I've been hopeful it's worked because large areas don't seem to be growing much. However, I have found that many hairs come out when I gently pull on them - I would never have been able to do this before as that hair is far too tough and coarse! However the 'loose' ones, when removed, do not appear to have a root. Is this normal? Does this mean the treatment has been ineffective?
