For me it's not about products but more about how much moisture is in my hair, and technique. If my hair has too much moisture in it (like from my rinse-out), it tends to dry much straighter and not hold a curl well. Also, the technique for drying it... if I just brush it out it'd dry straighter, but if I scrunch it, it will be wavier. Products can help make it more manageable, but for me moisture level in the hair and technique make the biggest difference.
