How about dry shampoo?

I have wavy hair that sticks up a lot, so I have to wash it the night before to sleep so it looks like a completely different person's hair lol.

I've been doing just fine so far using the "bangs-only washing technique" that women know about, but I think using dry shampoo would be much more convenient!

For those who have used it, what do you think? Is it undetectable and are you satisfied?
