Getting longer darker hair on my neck and face that i never had before after laser, what is this?
Doctor Answers (1)
A common or uncommon problem
Once the hair grows back finer after treatment, it becomes more difficult to destroy. If your skin can tolerate it, the energy level will have to be increased in order to destroy these finer hairs.
A much less common problem is scattering of the laser light to areas where you have NOT had laser treatment. Very low levels of laser energy, paradoxically, can stimulate hair growth in those untreated areas. If this is the case, you can have these areas treated with higher energy levels, or have them threaded or waxed and the hairs may not grow back long and dark once the other treatments are completed.
