Have your mom read about the method, show her how much it could help your hair. However it does not work for everyone! I have been CG for 5 months and it has been really good for me. My coarse hairs have gotten much softer and tamer. Find a conditioner that has some cleaning agents in it and use that as a shampoo (make sure to wash it out enough do that your hair doesn't get greasy) then condition and do everything else you normally do as usual (without sulfates).
