I have unbelievably dry curly hair. My hair could look perfectly fine and healthy and within seconds of touching humidity, I turn into a Chia pet. Pony tails and headbands are the only thing that saves me in humidity. While I haven't tried going for extended periods of time without shampoo, I do only use it on Sundays. I use conditioner every day. I also only "brush" with a pick and only when my hair is damp. I also always have to use an extra strength product to keep it in place and even then, it won't hold all day.
