Okay so if this is happening frequently it may be a fungus on the head. Which is very easy to fix... Go to your local pharmacy and apply "Lotrimin" fungus cream. Works like magic and it goes away over night. Whenever I see my cherryhead Sheldon's head get a little dry like yours I apply it on and it turns bright read over night! Love the cream. Apply it on with a q-tip.. Make sure you be careful not to get it in his eye.. Hope this helps!
