So, this was not a thread about No poo method. You can look it up and learn how to properly do it. Personally, I'd use a shower cap on rare occasion when I don't have the time to wash and dry my hair.

I've read sometime ago this one white girl tweeted that she hadn't washed her hair for over a year and that caused a sensation of some sort, and from what I've read, it's not that unusual for ebony hair to not wash often and keep the hair healthy and stink free by oiling it with some products, which is what this girl did.

Dry shampoo. I've never tried it, maybe it's an option for someone or in case of an emergency.

My general understanding is that the shampoo is made stronger to remove the oil from hair follicles than shower gels, so I'll have no problem using weaker products on my head to wash it clean. Personally, I'd just feel icky to just wet my hair, would be harder to manage thereafter too.
