I have 2c hair that is both oily and frizzy, so I've been thinking about using a tea rinse. I was wondering if it had to be either straight up black/green/peppermint tea or some kind of homemade herbal mixture (I've seen posts talking about those), or if I could literally just use any tea I have sitting around the house (tons of random herbal and black mixes I just didn't like the taste of).
