Until recently I rarely slicked my edges down. Somehow the way I was doing it made it look unnatural. I have a better technique now and I'm wearing more updos now. These are the products that work well for me.

Curls Passion Fruit Curl Control Paste
Eden Bodyworks Temple Balm
Blue Ecostyler

But my very favorite is Silk Elements straight Edges. Love this. And it is CG friendly.

What works for my curly friends?
Yes, it's real. No, you can't touch it.
