Q: I’m 27 years old and my hair gets extremely oily—normally it’s greasy every other day. Recently, I’ve also noticed a layer of dandruff on my scalp that can be scraped off with my fingernail. How should I treat this?

A: This is seborrheic dermatitis. I recommend washing your hair frequently. Use 60 g of Platycladus orientalis leaves, add 3,000 ml of water, boil down to 2,000 ml, and wash your hair while it’s still warm.
