Clary sage oil contains the same linalyl acetate that helps make lavender oil so effective in increasing hair growth. It can improve hair strength, in addition to increasing hair growth, making hair more difficult to break.
Mix 3 drops of clary sage oil with your favorite conditioner, or with 1 tablespoon of carrier oil. If using it daily, rinse out after 2 minutes. If using it once or twice per week, leave it on for 10 minutes.
