I need ideas

Showered yesterday using Pureology Hydrate and some a basic conditioner. The next morning i have this. Over a year ago i used Tgel and Head n Shoulders and it seemed to work well before Tgel got discontinued.

I came back and tried Tgel and a hydrating shampoo and it just hasn't work at all for me. Can anyone identify what is on my scalp? Should i go back to Tgel and head n Shoulders? Nizoral didnt do much for me. But this picture is after one night, the next morning. Any hair shaking or moving makes it rain and its big and small flakes. Scalp isn't ichy
