New York Post ( Weleda Rosemary Hair Oil)
by New York Post
Apply Weleda's Rosemary Hair Oil, ($12 at usa.weleda.com) to clean scalp, roots and ends, coating your entire hair in the delicious-smelling grease. Head out for 20 minutes in the sun and let your head heat up naturally, causing the oil to penetrate. We suggest leaving the oil in as long as you can, even overnight. To get it out, wash and condition as usual.
