SO, after going through this thread yesterday, I am not washing my hair today (day three) - I usually would on a work day but I think I will start trying to stretch it out a bit more.

I have frizzy hair too. It's more about the products post wash that you use rather than the ones you use daily. I have a refresher spray in between days, so you only need to use product on the first day and refresh after that. When I use curling product to defrizz my hair I actually end up with better hair after a sleep with the product. (And please if you use product in your hair and sleep in it... protect your pillow with a towel and turf in the morning... or you'll end up with residue on your pillow case... or worse in your pillow which can lead to bacteria and pimples and all sorts of yuckies!)
What products do you use?

And for those of you who use a dry shampoo, is it good for your scalp? Because I am thinking, you're leaving stuff in there...is that ok?

When I shower but don't wash my hair I just twist it up & keep it as dry as i can, it gets damp around my neck & hairline but dries quick enough.

I'm really low maintenance WRT my hair; maybe if I put more effort in it wouldn't look so yuck
