Rinse her hair w/ Apple Cider Vinegar after shampooing - it is a fantastic conditioner! Fixes the tangles and the frizz. Use 1/3 ACV to 2/3 water. The smell does not last long. I promise it works :)
**Only comb with a wide tooth comb - do not use a brush. And no, using a wide tooth comb does not cause frizz. If I use my fingers, my hair is frizzed out like a clown. My hair stylists, throughout my life, told me to never use my fingers on my frizzy hair.
