The first website is the actual CURLS website, the folks who produce this milkshake
you've been hearing of. Before you buy, try a sample from sistasplace. They ship quickly, and you can sample a few different curls products for not much money. And if you hate the sample, you can swap it for something else on the swap board. Curlicious also carries this line - I only found out about all these sites when I first discovered curls. sometimes curls.biz doesn't have what you're looking for, hence trying the other sites......
Good luck, and please, for the love of god, DON'T put a straw in the milkshake
and go to town. IT"S FOR YOUR HAIR! Same goes for the whipped cream. Consider yourself warned....
