Some women hesitate about coming in on a monthly basis because they anticipate the pain and make the decision to put it off as long as possible. The more regular you get it done, however, the less it hurts. And the longer you grow your hair, the more painful it can be. A woman came in on Friday who hadn't had it done in several months. She had a lot of hair. Last night I got a text message from her saying that she had the GREATEST sex that night. ME happy.
