A woman had colored her hair a lot and it was very damaged. When she went 'no poo', she focused on nourishing her hair with natural oils like argan oil. After some time, not only did her hair become less frizzy, but the color also seemed to last longer. She believes that without the harsh shampoos stripping her hair, the color could stay better. Also, her hair regained its natural bounce and softness which she hadn't had in a long time.
