Castor & rosemary oil blends
Castor and rosemary oil blends combine very thick castor oil with a lighter base and rosemary-derived ingredients. Formulas vary: some use rosemary essential oil in a castor-heavy base, while others list castor oil behind several carrier oils. The ingredient order and concentration information are more useful than a front-label promise about growth.
These products are compared by current price per fluid ounce. Read the full ingredient panel for fragrance, peppermint, and other essential oils that may irritate a sensitive scalp, and do not apply undiluted essential oil directly. A blend may rinse more easily than pure castor oil, but unit price is a cost comparison rather than an effectiveness rating.
