I know a bunch of women who, aside from showing their daughters how to wash their naturally textured hair, let their daughters do whatever they want with their hair. With all the chemicals, dyes, sprays, ect. out there...is there an appropriate age to teach a young girl about how to deal with their texture in a healthy, happy way?

And what is the best age?  I feel it's best to teach kids when they become conscious of their appearance.   What age to you believe that is?
