You are dying it fairly often. Are you bleaching it when you dye it? Bleaching and the amount of time and bleaches for can do major damage. I once dated a girl with dark brown hair she tried to make it gray. She only bleached it twice but it would literally just fall apart. So the darkness of your hair what they say how long it has to be smothered and chemical to get your results. You can only do so much with products.

In case you haven't noticed, everyone's hair is different. Just because your friend dyes/bleaches and uses tons of heat and her hair still looks fine.. doesn't mean that your will react the same way. We all have different hair types and harbor different genetics. Take better care of your hair between dyes, or stop dying it so much. Your natural hair color is good enough.
