Hi geeks just wanted some advice from the hair dressers I had a strand test done the other day as I wanted to lighten my hair my hairdresser was going to put a base 9 and then something else I can't remember on but once she done the strand test it showed that my hair is still weak and will snap easily now my question in would I still be able to dye my hair if I went darker instead? As I wanted to put extensions in once I have had it dyed but I don't want to put them in if my hair will snap easily still any help please??? Xx
