Query: Fantastic product!

I stumbled upon this product by chance, and I must say that it is the BEST product that I have ever tried. I have wavy, coarse hair and it does wonders for it. I also have a greasy scalp and this product takes care of that problem for me! Simply LOVE it! My daughter has thin, shiny hair that she blow dries and she didn't like the product as much, though.
