Curls are so different from person to person. On Brooklyn's recent post, she complained of her frizz, so I suggested the book, Curly Girl Handbook, by Lorraine Massey. She dedicates different chapters to different types of curls. It was life changing for me - for under $10!
That being said, it sounds as though you have 2c/3a type curls (fine, curly)? You may need to Google or You Tube to understand that.
I have somewhat similar curls (2b/2c). Sulfate free shampoos are critical, but first it sounds as though you may need a clarifying shampoo to truly clean out residual products. I do this every 1-2 months.
I love the Devacurl line of products. I use:
1. No-poo shampoo & Delight Conditioner.
2. After washing it out, I scrunch in Supercream styling cream while I'm in the shower and scrunch, scrunch, scrunch.
3. Once out of the shower, I scrunch in Frizz Free Foam.
4. I finish with scrunching in Arc Angel Gel. Lots of scrunching.
5. I always use a diffuser with my blowdryer (medium heat).
6. The final product may look crunchy (gel cast), but then you just scrunch out the crunch once your hair is dry to get looser curls.
