I have very thick, naturally curly hair and frizz is a constant. I was introduced to this product at a salon that offers "Curly Girl" haircuts. The stylist barely cut my hair, but the way she washed, conditioned and styled it was AMAZING. NO frizz. She used Deva Curl shampoo and conditioner and then this AG Curl Details defining cream. 1 - barely use any shampoo - just clean the scalp. Shampoo must be sulfate, paraben, and silicone free like Deva Curl. Sulfate free shampoo does not bubble up at all so it can be hard to get used to that, but you should only be cleaning your scalp anyway. Your hair doesn't need or want shampoo. In fact, skip shampoo if you can and just use fingers to rub your scalp. The salon also suggested using course sugar instead of shampoo so you can feel the grit cleaning your scalp, but your hair won't have to deal with shampoo. 2 - conditioner - must be sulfate, paraben, and silicone free like Deva Curl. Condition as usual, but instead of rinsing, just drizzle water over your hair to partially rinse, leaving most of the conditioner in. % left in depends on how dry/thick/frizzy your hair is. At home, I use an empty water bottle to drizzle and I leave in about 98%, lol. 3 - Immediately apply styling product: while still in the shower, tip head upside down, gently squeeze out extra water in hair, then very gently apply styling product trying not to disturb the curls. I have long curly hair and I use about a half dollar worth of the AG Curl Details defining cream. 4 - wrap hair in a microfiber towel. Gently squeeze hair with microfiber towel to remove excess water. I don't use a dryer, but she did at the salon. With a diffuser and NOT disturbing the curls. 5 - no combing, brushing, running fingers through your hair, etc. Do everything very gently. Disturbing the curls adds to the frizz factor. Once your hair is dry, you have soft, beautiful, bouncy curls and no frizz. SERIOUSLY!!!! I have tried other products in place of this defining cream including Redken Curvaceous cream and Paul Mitchell The Cream. Paul Mitchell The Cream worked almost as well, but AG still wins - no contest. As a side note to other curly girls, I was SO excited to see the new Paul Mitchell Curls line - and it's sulfate free. DO NOT WASTE YOUR MONEY!!! Using the same regimen above with PM Curls products - my hair was curly all right, but frizzy curly, like when you go to Louisiana or Jamaica and the humidity is like 99.9%. I used it several times to make sure it wasn't just the weather or something. AWFUL! so sad. But it does make me appreciate the products I've found, including this AG cream even MORE. It's magic!
