Castor oil may not necessarily thicken your hair. However, it does condition it, which may make it appear thicker. Containing Omega-6 fatty acids and vitamin E, castor oil is extracted from castor beThans and has been used medically for centuries. Its use dates back to ancient Egypt and Rome and is approved by the U.S. Federal Department of Agriculture for topical use. Using natural castor oil as a hair treatment may give you the results of thicker and healthier hair.

Things You'll Need

Select a high-quality castor oil that is suitable for cosmetic or therapeutic use. Jamaican black castor oil is a type of castor oil chosen often because it has a lighter consistency than the other types. It is also a “raw” and unrefined, so it has been processed less and has retained more of the nutrients that help hair health. Organic castor oil should provide the quality desired as well.

Pour 1 tbsp. of the castor oil into the palm of your hand. Using your fingertips, massage the oil into your scalp, the roots of your hair and all the way down the length of your hair. Make sure the oil is evenly distributed on the entire surface of your scalp.

Pour 1 tbsp. of jojoba oil into the palm of your hand and distribute it evenly throughout your hair. The thick consistency of the castor oil may make proper distribution difficult and using jojoba oil helps to spread the oil easier.

Place the plastic hair cap on your head then wrap your head in towel. The plastic cap will hold in the heat generated by your body and the heat helps the oils to penetrate deeper. Allow the oil to saturate your hair and scalp for at least 15 to 20 minutes, or overnight.

Wash the castor and jojoba oils out of your hair after the 15 to 20 minutes or overnight period with a mild shampoo, making sure the oils are completely removed.

Towel or air dry your hair and style as usual. Repeat this castor oil treatment once a week for between six and eight weeks.
