1. how often to wash

I usually shampoo my hair twice a week, on the in between days, I just wet it in the shower and put some conditioner on it.

 

2. morning vs. night

I prefer night because that gives it time to dry before I have to go anywhere.

 

3. drying

I always air-dry.  Always.  No matter what.  The less the hair is handled while drying, the less frizz there'll be, and the curls will form better.  Use a towel to squeeze the water from your hair (squeeze, don't rub!) then don't touch it.

 

4. products

It's possible that the styling product you're using is making your hair greasy.  You're probably using too much.  Try using less of it, or try a different product.  Using your palms, gently smooth it through your hair without running your fingers through it.  (I prefer simple aloe vera gel.  I apply it when my hair is mostly dry.)  If there's some frizzy spots, you can do spot touch-up by misting a little water on it with a spray bottle and smoothing it down. 

 

5. combing

No combing.  The only time I ever comb my hair is directly before washing.  It is good to comb your hair, don't get me wrong.  It helps stimulate scalp circulation and increase healthy hair growth.  But don't comb it while styling, it separates the curls and causes major frizz.

 

Hope that helps you out some!  How long is your hair?
