I have dark black hair, and I want to lighten it to a medium-dark brown.
I have medium length hair for a guy.
I've read that I can use lemon+water solution to break down melanin in my hair slowly in the sun, or use a hairdryer too. I wash my hair often because using this trick will dry out my hair.
I know that black hair has a LOT of melanin, so this process is slow, but JUST how slow will this take?
How many times would I have to apply lemon juice + water, and hairdry my hair (over the course of many days) to see a noticeable difference?
I see mixed comments when looking at DIYs and online blogs about this, some saying that only brown hair and up can lighten using this trick, while others say black haired people can lighten too, but just more slowly.
