I found a new product for you to try on DD.
http://www.target.com/p/Shea-Moisture-Coconut-Hibiscus-Curl-Style-Conditioning-Milk-8-oz/-/A-12239779Shea Moisture Curl Milk. I like it b/c you can apply it to wet or dry hair. So for DS, I put it on his hair after his bath at night. Then in the morning I put a little more to revive his curls. It's sold at Target and Walgreen's and it's organic and cruelty free. I AM NOT A VENDOR.
