No source. I just found that shampooing every day caused my hair to get really oily if I missed a single day of shampoo. After not shampooing for an entire week I went down to doing it twice a week and excess oil is no longer an issue. I have semi-curly hair as well. Going to give no shampoo at all a shot next.
