Lighten short hair with lemon juice. HOW LONG WILL IT TAKE?

I have short hair...like just over a cm long and heard you can lighten your hair with lemon juice.

I heard you have to put lemon juice on your hair and go out in the sun for about 2 hours... but How long will it take to lighten the hair?



I have medium brown hair.

I think just get some bleach... use very little so not to burn your scalp- but come on, do you honestly want to stand out in the sun for 2 hours with lemon stinking up your hair? Lighten short hair with lemon juice. HOW LONG WILL IT TAKE?
buy sun in it makes your hair lighter and on the bottle it tells you how long to put it in for
