In short

Across 16 castor & rosemary oil blends listings, the current median is $2.42/fl oz and the lowest is $1.14/fl oz (Aromatico, 7 fl oz), as of Oct 30, 2026, 4:03 PM ET. Unit price measures cost only — no castor oil has demonstrated a hair-growth benefit, so nothing here is ranked on effectiveness.

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.
