Of all the different methods available for hair removal, only medicalized laser hair removal is definitive.

Other shaving techniques, manual waxing or the application of depilatory creams can only provide ephemeral results, and are ultimately much more restrictive because of their frequency.

During a laser hair removal session, the target is the root of the hair.  This is destroyed by the laser, which selectively deposits significant thermal energy. Melanin, the pigment that colours the hair, is directly targeted.

The depilatory laser will be reserved for dark-coloured hairs (thus containing more melanin) and in particular those in the growth phase (because they contain a large quantity of melanin during this growth phase). Consequently, Laser hair removal of very light or even white hair (containing very little melanin) is impossible.
