None of the laser hair removal systems will be effective in removing blond or white hair. The hair needs to be dark to absorb the laser energy. Electrolysis may be an option for you.
Will Lightsheer Work on Blond/white Coarse Hair, Type 3 Skin, Also Fine Blond Hairs?

Electrolysis is your best option
Lasers/light devices do not work well with light hairs, especially in darker skin tones. Electrolysis, which uses a small electrical current to destroy the hair follicle, is your best option. Since it is pigment blind, any color hair can be treated.
No laser, not even the LightSheer Duet will remove blonde or gray hair
The way a laser works to remove hair is by heating up the hair to the point that the hair producing cells are damage to where they are unable to produce hair anymore. The hair is heated up because the laser is attracted to the pigment. In gray or blonde hair, there is no pigment, so the hair doesn't heat up, and the damage does not occur to the hair producing cells. Even what is considered the best laser hair removal device, the LightSheer Duet, will not work on gray or blonde hair, nor will any laser on the market. The only viable option is electrolysis for this type of hair, but that is painful and very tedious.

Laser hair removal does NOT work on Blond/White Hair
I would like to echo Dr. Baolgun's comments. Without melanin (the pigment giving color to hair), then there will be no effect of any laser on the hair. The only method to permanently remove blond/white hairs is electrolysis. Even dyeing the hair will fail to produce an effect with laser hair removal.
