I never used products or did treatments before I started lurking on nc.com almost six years ago. When I started, my hair was winter wavy/summer 3a. The things I learned here have strengthened my curl pattern. My hair now looks like my signature picture every day, all year around. I don't look for products that provide hold, my hair doesn't seem to need much.

I wet, use a rinse out and style every day. Don't try for second day hair, so I can't really answer that question.

What I would say to your science brain is that the correct balance between moisture and protein will optimize your curl.
