The bleaching process in itself doesn't really "hurt"
as much as it.. stings? And it makes your scalp itchy.
The real dmg is done to your hair, bleaching can
make your hair brittle.
I did it myself, turned black into white/silver. ^.^

Maybe it will sting a bit - your scalp...
The darker your hair is, the longer it will have to stay on. And it will damage your hair - a lot and permanently.
