Laser hair removal only works if there's contrast between the skin and the hair. So if you have white or blonde hair and white skin, it doesn't work; or if you have brown skin and brown hair, it also doesn't work.
For cases where laser hair removal won't work, there's electrolysis, which involves inserting an acupuncture needle in each and every hair follicle, but it's expensive, slow, and can be pretty painful.
When you have laser hair removal, the laser flash pumps a ton of energy into the hair follicle which essentially roasts the shit out of the hair follicle so it dies, usually it will re-product hair at some point but very thin, wispy white hair if any at all.
You need to shave your hair for laser hair removal since you don't want a long melting chunk of hair on your body that will cause serious burns. Hair dye will not color the root base of the hair meaning that heat energy will not travel down to the base as well and probably just destroy the pigment dye instead of the hair itself.

But, hair can be dyed?

Sort of. It's often not perfect, and often not permanent.
mostly, but not always, and it's harder if there is less contrast between hair color and skin color.
