You just didn't have the luck and circumstance to get on the generic track that almost guarantees success in this country. Think about it, Joan had the great Berkeley education, the internship at Vogue, all those connections in NY and California. I think for people like Didion, New York and California are the only states of any real consequence in this country. She certainly wouldn't be travelling to any of the other 48 for a vacation. Except, of course if it was to report a story, right Joan. Is this product review negative?

After my first attempt I had limp curls that did not last longer than 1 hour. On my second attempt I did it on dry hair with very little products added as I though the moisture from my styling products may have made my hair to limp, nope. On dry hair with minimal product had the same limp hair. Needless to say, the caruso set went right back to Amazon for my refund. I have 4A fine relaxed hair, so this product may be great for those who tex-lax or ladies who are natural with thicker hair. Is this product review negative?
