I'd suggest getting a copy of Curly Girl: The Handbook for the two of you to read, and to watch the video clips together. Even if she's not ready to take over her own haircare, she's probably got some strong opinions about what she likes, what works, and what doesn't (or outright hurts). Doing this together, at this point in her life, will probably make her teen years easier for both of you.
Peace,
