I apologize if this has been posted before. I'm new! :P

Was wonder if anyone had any tips, or suggestions for training curls to be tighter, naturally?

I am learning to love my curls, recently did the "BC" and am wanting to go as natural as possible (with the exception of dye. My gray still embarrasses me!)

I'm about a 3a, but would love to train my curls to be closer to 3b, or tighter.
