My hair is also fine and fairly straight, and CO washing just doesn't work for me - it gunks up my hair and weighs it down, and my scalp tends to break out, too. My hair and scalp are much happier with a gentle S&C and careful handling. I wash my hair every other day, sometimes stretching to that third day, but by then I'm pretty oily - ewwww. I think there may be something to the idea that CO is best for hair of a medium texture, dry, curly. Any other thoughts?
