Can Laser Hair Removal Have Adverse Hair Growth Effects?

Laser hair removal will only work on the area of treatment. There is no evidence that it will affect distant sites. 

Laser hair removal in one area of the body will not affect another area. Recent research has shown that low fluence (low energy) laser or IPL treatments can actually stimulate hair growth. This occurs when the hair follicle is not heated to a high enough temperature to damage the blood vessel that feeds it. Instead, moderate heating at low energy levels will actually stimulate hair growth.

There have been growing literature in dermatology and laser surgery that hair laser removal, particularly used with an IPL (intense pulse light) laser modality can paradoxically stimulate more hair growth. You should look for Nd:Yag laser removal which may be less likely prone to this unusual side effect. In addition, seek an experienced dermatologist who is familiar in using spironolactone to suppress androgen for women.
