Electrolysis treats each hair follicle individually with a very fine, disposable, sterile probe to permanently destroy the follicle’s ability to reproduce, thereby eradicating hair growth on completion of the course of treatment.
Laser tends to treat large areas of skin using a laser or light based lamp which can substantially reduce a hair growth, but not remove all of the hair permanently . It is termed hair reduction rather than hair removal. Several BIAE members perform both electrolysis and laser (or IPL, which is similar to laser) as the two treatments can work well in conjunction with each other in some circumstances,. Permanent hair removal with electrolysis requires a longer course of treatment but results in complete, permanent removal of all hair.
