I'm someone who has been dyeing my hair since I was a teenager. (30 years ago) and I can say that certain dyes have been nicer to my hair then others. It could be fine on one person's hair and not on mine. There have been semi permanent dyes that damaged my hair and I should have known because their permanent brand did not leave my hair in very good condition and this was on virgin hair for the permanent dye. I've just recently started using semis and they are great at freshening a color especially reds bit I did have my hair damaged by 2 of them. Some people's hair I think just doesn't work with the chemistry of some dyes. And you may never know until it happens. Try a strand test before using to make sure it doesn't make your hair break off.
