Ecostyler (Sally Beauty Supply) made my hair heavier and a bit straighter. It's a heavy gel. Miss Jessie's Curly pudding will do it if you do the "shingling" method. Actually any styler with the shingling method will straighten the curl. Google Miss Jessies for instructions.

Hear that crash? It's me falling off the CG wagon.
