Pure cold-pressed castor oil
In short
Across 10 pure cold-pressed castor oil listings, the current median is $2.00/fl oz and the lowest is $0.27/fl oz (US+, 128 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.
Pure cold-pressed castor oil is the simplest option in the hair-oil aisle: one thick oil with no lighter carrier oils or fragrance added. People commonly use it as a pre-wash treatment, on dry ends, or diluted for scalp massage. Cold-pressed describes extraction, while hexane-free describes what was not used during processing; neither phrase proves that an oil increases hair growth.
The table compares current Amazon listings by price per fluid ounce so small droppers and large bottles can be judged on the same basis. Castor oil can be difficult to spread and rinse from fine hair, so many users dilute it with a lighter oil. Check the ingredient panel, patch-test before wider scalp use, and seek medical advice for persistent shedding or scalp symptoms.
