My hair is a medium brown as it is, about the color of Alexa Losey's hair in this video: http://m.youtube.com/watch?v=AWFN8nSfXlA
I've never dyed my hair before, so do you think using one of those 28-wash semi-permanent hair dyes will damage it? Basically, how much is too much--when do hair dyes start to extremely damage one's hair? Also, I am looking for a hair dye that will dye my hair a darker shade of brown, around the shade that Alexa Losey has in this video: http://m.youtube.com/watch?v=5ZpDZiMhotw but again, I'm looking for a 28-wash (semi-permanent) hair dye. Thanks!
