I got this as a large sample in a frizzy hair kit that I purchased. I tried it on my fine but super curly hair and it was a bit much. It left me feeling slick and weighed down. But, then I did it as one other reviewer mentioned and used it as a mask that I rinse out, worked great!
Since the sample came with two packs, I gave the other to my mom. She has course hair that is super curly. She LOVES it! It leaves her hair soft and manageable. So...I'm buying her a full sized one as a gift. She'll be thrilled and the price is right! Win win!
