The best way to use Cedarwood Oil for hair loss is to avoid using shampoo. Instead use it as follows. Mix a few drops of cedarwood essential oil with 2 tablespoons of any carrier oi,(coconut oil, or olive oil works great), Massage it into your scalp and leave it on for 10 minutes before washing it out. Wash if off ONLY if you do not like the oil in your hair otherwise leave it on all day and night. Must do this on a consistent regular basis as it is not an overnight solution for hair loss.
