I wash my hair twice a week. Twice a week with shampoo. However, on weeks when I'm stretching and need to encourage my hair to retain more moisture, I only lather with shampoo ONCE per wash. So I rinse my scalp really clean, shampoo, but only lather once. I also, only wash my scalp, as your hair is cleaned by the shampoo that runs down your scalp. Lastly I follow each with a deep conditioner of at least an hour. On saturdays I condition twice, once with a cholestorol or mayo if I need more protein, and then follow it up with a moisturizing conditioner. If my hair has been feeling dry lately, I will also condition with heat on Saturday.
