I know how you feel! I would suggest tea tree oil or peppermint oil.

If you use peppermint oil, you only need a few drops. The oil cleans old folicles of dirt and sweat. Tea tree oil is an antiseptic, effective against bacteria and fungi. If you use either oils, make sure you get your scalp well (:

I hope I helped!
