If you have no new hairs that come up, you still have more “old” hairs than you probably think. All hair goes through 3 stages of growth. During the last “shedding” stage, the old hair is shed and not visible on the surface. However, the follicl that it grows from still remains an active follicle which will produce another hair in it’s place. On the chin, the cycle usually takes around three months. This means that if you had PROPER and TIMELY treatment during this time, than almost all of the hairs were treated.
So why in the world would it take longer than 3 months???!
Well, there are many factors which are responsible for this.
The hair is most susceptable to treatment during the early fist stage (anagen) of growth. Later the hair papilla becomes stronger and harder to kill. Moreover, a percentage of the hair is in transition and shedding phases. It means that the hair isn’t growing at the time and is disattached from the papilla. The papilla could be hiding deeper in the skin, and there is less moisture, which is needed for electrolysis to work. This is why it is advisable to shave the area a few days before treatment to make sure that all the hairs that would grow out to be treated are anagen.
Extra coarse hair or deformed follicle can limit the effects of treatment. Especially if you’ve been plucking before, you may have a lot of deformed follicles. Still, after a few good treatments ALL hair will be gone forever and, in most cases, you should be done in about a year.
Incompetent practitioner is among other possible causes. Unfortunately, this would include most practitioners out there. That’s why as James’s mantra goes: get as many consultations and sample treatments as you can! As a general rule, you shouldn’t feel that the hairs are being plucked. Ideally, you shouldn’t feel them come out at all, but a little tug is sometimes not avoidable.
All this goes if you don’t have your hormones stimulate more hair growth as a result of pregnancy, menapause, puberty, aging, medical condition, etc.
