I don't really have specific days that I wash. I just make sure to wash on the weekend and then midweek. I settled on this schedule because in 2001 I discovered a regimen that suggested washing hair only when it felt dry. That's when I stopped using leave-ins. I'd just go about life and on the day my hair felt dry, I'd shampoo and condition to add moisture to it. Over time, it seemed this would happen every 3 days or so. So I would wash every 3 days. When I learned about DCing, I realized making the weekend one of the times I wash would allow me the time to DC. So my schedule became twice a week washes, rather than every 3 days. I still use no products after the wash, and this schedule works for me.
