Rosemary has an excellent reputation for oily skin/acne, scalp and hair care, and i have repeatedly read that rosemary oil can be helpful with alopecia (hair loss). Rosemary is quite stimulating and is heralded for help in memory retention and staying focused and alert. Rosemary is a good choice for blends for driving long distances and for long study sessions.
