Do you have a source for that? I have super curly hair and in a futile attempt to manage it I researched hair care for a morning a few weeks ago.

If you didn't know curly hair tends to become dry towards the ends. This is due to the natural oils not being able to reach the ends because of the curls. I found a few sites advocating shampooing about once every two weeks to let the oils do their thing (along with moisturizing conditioner every day).

That being said my hair is still a mess so I'd love to see if I am "doing it wrong".
