Yes, you have to wait until the hairs grow out again, which can be up to at least a week plus. Waxing will not make the hairs go darker. The constant pulling out of the hairs via waxing, electrolysis and hormones will turn them fair and thin.
It is such a long time ago, its hard for to me to say what actually happened at the time, mainly because I was working and had no time to think about the changes that were happening to me. Worked during the week, partied with colleagues and friends on Friday night , Saturday morning shopping and around midday I had my electrolysis appointment and Sunday afternoon was set aside for waxing and other beauty treatments. Eventually I realized that sometimes I did not need to wax and occasional pluck with tweezers was all that was needed eventually waxing was not needed any more and electrolysis continued until I was totally free.
I did not use waxing using strips, I used wax that you heated up, allowed to cool and they applied it to the face using a wooden spatula (a large ice cream stick or tongue depressor) and when it was solid pulled it off.
These were the times when laser was not around. So I did not have that option at the time. I hope this clarified a few things for you. If you still have some questions please ask, I and others will help you if we can.
I agree with Gabrielle tell them you are ready to move on and you do not want any more damage done to you by the hormones that are in your body at the moment. If the treatment is not coming forth with, seek another therapist.
Wishing you luck in getting that job.
Kind regards
