I BELIEVE in the use of essential oils in hair care, skin care and various natural household uses. The following concoction should last 4-6 months even with daily use.

Materials Needed

Small dark glass jar (the best for preserving oils and preventing spoilage)
Measuring Cup

Recipe: Essential & Carrier Base Oils for Thinning Hair

7 Drops of Rosemary 100% Pure Essential Oil
5 Drops of Clary Sage 100% Pure Essential Oil
2 oz (1/4 cup) of Jamaican Black Castor Oil Carrier Base Oil
Essential oil mixtures require a carrier base oil. The more essential oil you add the more carrier oil will be required to dilute it in order to avoid irritation. To learn more about what essential oils and carrier oils are  click here.

Please note that thinning hair can be indicative of serious health problems. I have had a through blood work up by my holistic primary care physician and have spoken to more than one doctor about my thinning hair. They believe it is likely stress from my insanely busy life. Please do not use if nursing or pregnant. Please do a skin spot test before using to insure you are not allergic. Just because this is natural does not mean it will not interact poorly with your skin. Those with high blood pressure should note that rosemary is known to raise your blood pressure so consider an alternate oil like bergamot. 

Rosemary essential oil on hair is mostly used to stimulate hair follicles and increase hair growth. It is highly recommended for the prevention of hair loss as well as slowing the process of hair loss. 
Clary Sage is used to strengthens hair follicles, tone skin, as well as stimulate hair growth.
Black Castor Oil helps with hair growth and hair retention and serves as the carrier base oil. It is also a natural anti-bacterial and anti-fungicidal fighter which in turn protects the scalp.
