First, I tried to quit shampoo cold turkey. I rinsed my hair thoroughly with hot water only, and used no conditioner or styling products.
My hair and scalp are rather try normally, but they went into full revolt mode when I tried cold turkey. I typically washed my hair every 2-3 days before this little project.
The first day, it was ok in the morning. A little heavy, but tolerable. By the afternoon, it felt strange--as though my hair wasn't actually clean. Probably because it wasn't. It looked ok but felt icky. By the next morning, I looked like I was in the height of puberty and hadn't bathed for a week.
