I never get 2nd day hair, and recently I started experimenting. I've had great success mixing a small blob each of FOTE and LA Looks Sport Gel (the blue one). I smooth it on from top to back (like a pony tail), then bend at the waist and scrunch. After a short time, it's dry and I gently scrunch out the crunch.
It's nowhere near perfect 2nd day hair, but good enough that I feel comfortable being seen in public!
Somewhere between a 2c & 3a
-Suave Naturals or VO5 (co-wash)
-GVP Conditioning Balm (conditioner)
-L'Oreal Vive Pro Nutrigloss (conditioner)
-Giovanni Direct Leave-in or GVP Conditioning Balm as leave-in
-Flax seed gel (my favorite right now)
I have bangs now, and I love 'em!
