Hairdressers? I need help!

Alrighty so I dye my hair quite a bit. I haven't dyed it a lot recently, but I bleached it from jet black to make it blondish brown. After months and months of that hair I decided to dye it a reddish purple color. Well, my hair is kinda like dry and cracked and fried I guess I'm not sure I'm not a hair dresser. (An family friend comes and dyed my hair she's been doing it since she was a little kid) I was wondering if there was any good ways to help with that. It hurts to brush my hair. I went to the hair dresser and got a ton of dead ends cut off and it made it easier to brush, but it's still pretty painful. I can't find a good picture because normally I take pictures when my hair is still wet or right after I get my hair done so it normally looks pretty in pictures.
