Organic (USDA) castor oil
USDA organic castor oil adds an audited agricultural certification to an otherwise simple product. The seal addresses how the beans were grown and handled; it does not establish that the oil works differently on hair or make it a hair-loss treatment. Cold-pressed, unrefined, and hexane-free are separate label claims, so check each one independently if it matters to you.
These listings are ranked by current price per fluid ounce to show the premium attached to certification across bottle sizes. Confirm that the label carries a real USDA seal rather than relying on the word organic in a marketplace title. As with any leave-on oil, use a small amount first and stop if the scalp becomes itchy or irritated.
