Crazy as it sounds you make a paste out of Baking soda and rub it in your roots really good and it takes all the oil out, rinse and then put some apple cider vinegar mixed with water on the ends. If too dry which is a problem in the canyon Argan Oil from Morocco. The stuff is gold. I have really curly long hair and a quarter size of the oil and I can get a pick through it on my worst days. Works on dry hair too. I get mine on ebay. It's great for dry skin too.
