A bit expensive, buy try using the shampoo called "Big" by Lush Cosmetics. It's sea salt based with lime and it will surely reduce the oily days. It did for me too. I don't use it everyday because it can dry out my hair!

Nioxin is online. Also try to incorporate more veggies in your diet. That helped me. I got thicker hair and no grease.

I have the same problem. I just wash my hair everyday. But i would like to not have them so greasy

Nioxin helped mine. Also take magnesium to help your hair.

Mine gets super greasy if I dont wash it the best I've found for myself is head and shoulders I also hardly use conditioner because it makes it worse.
