Also got assam to drink since it's my favorite of all teas to drink next to oolong. I just wiki'd it and of course it is! Assam is the camellia plant grown in India. Oolong is also camellia but a different variety grown in China. My skin also loves camellia seed oil.
Anyway, that line of thinking led me to say, OK, I'll try assam to rinse. Regular black tea made my hair hard. When I'm feeling brave, I'll give assam a shot. If I dont drink it all first .
