Delighted you had a good hair day.

Try more massage with your low poo, and wash upside down so you get to the roots, massage as you rinse too. A lot of us get into the habit of using too much sulphate shampoo and not enough effort, then when when switch to a gentler method our hair is not as clean. It can take some weeks for the scalp to stop overproducing sebum when you quit harsh shampoos. If it doesn't improve try a different product, it may be you didn't get the right one for your hair or skin.
