"Soothing TEA TREE OIL Shampoo" from Hairtherapy.
Omg, guys. It was fairly inexpensive, the tea tree oil factor makes my scalp calm and the smell is delectable. It's got aloe in it too, for the itchies and whatnot.
So, yeah. Just a suggestion for those who would like an alternative to an application of straight tea tree oil to the scalp.
