I couldn't open shtow's link that was referenced above. I want to try flexirods to maintain soft bouncy curls but am having a hard time figuring out how to use them.
I heard foam wrap helps for wet set. I set my hair dry on flexi rods at night to keep the curl bouncy and fresh. I'm on day 7 hair now. Got that tip from @shtow. http://www.longhaircareforum.com/showthread.php?t=471894
In the spring/summer I use a creamy leave-in - NTM and a little serum on the length of wet hair before I roll.
The serum is what keeps the strands smooth and frizz free.
