Does vitamin c really lighten hair?
I tried on mine but it didn't seem to work at all. but I have watched so many YouTube videos and also read a few web pages and it says it works. But why didn't it work for me? I used 35 tablets crushed up (using a pill crusher) and the normal amount of shampoo I use in my hair with just a bit extra. I left it on my hair for 1 and a Half hours, and washed my hair. (my hair is dyed black) and it is still black.
