I know I won't stop until every last one of the repulsive things are gone. Hair on my face discusts me to a point beyond words. And, every time I feel that little pinpric pain I halfway smile knowing it's another facial hair dying.
Emilie's right 3 times per week is way too much. In fact, treating that much you could actually stimulate more and/or new hair growth. I treat once every two weeks, sometimes every three because you have to allow time for those dead hairs to fall out, or "eject." Let me assume here that the day after your treatment it actually feels like you've grown more hair or accomplished nothing. The ejection process will feel to the touch as rough hair growth. However if you wait a week this will begin to get noticeably thinner in the treated area. And after around two weeks you can accurately gauge how much hair is left in the treated areas.
Your getting ingrown hairs because the frequency of your treatments are most likely stimilating new hair growth -especially if you go over the same area multiple times during each session.
A couple of other things to consider are the three cycles of hair growth: Anagen =active growth phase, Catagen =degradation phase, and Telogen =the resting phase. Lasers and pulse light devices are only effective during the Anagen or active growing phase. During the other two phases these devices are ineffective. And when it comes to facial hair, only about 30% of the hair is in the Anagen (growth phase) at any given time. So each time you treat your only treating 30% of the hair. And because the resting phase can last between six weeks and up to six months in some individuals this is the reason that multiple treatments over a one to two year period will be necessary to remove most of the hair. Facial hair is the only hair on the body that only has so little - 30% in the growth or Anagen phase at one time, so therefore it takes the longest time to be rid of say compared to leg hair which 62% is in the Anagen (growth) phase at a given time, and thus will take less treatments to remove.
I've done alot of research on the subject so I could understand laser treatments and how they work so I can be as most effective as I can doing it on my own. Just be a little more patient with your treatments Missadventure and you'll start seeing better results. Hope this has helped some.
