VITAL AFFAIR Organic Castor Oil with Rosemary is a cold-pressed, hexane-free blend positioned as a scalp stimulant and hair strengthener. The product combines castor oil (rich in fatty acids and vitamin E) with rosemary oil (traditionally linked to follicle stimulation) in an 8 fl oz glass bottle at ~$2.37/oz.

Hero benefits: Scalp nourishment, hydration, and the appearance of fuller, faster-growing hair. Applied via dropper to scalp or hair roots.

What the evidence shows: Castor and rosemary oils are well-documented moisturizers; rosemary has modest peer-reviewed support for scalp blood flow. However, "hair growth" claims remain largely anecdotal in mainstream dermatology—no clinical trials cited. The brand (VITAL AFFAIR) is a white-label player with minimal third-party trichologist endorsement.

Realistic positioning: Works best as a scalp sealer and hydration oil for dry, flaky scalps. Growth results are user-dependent and typically modest. Suitable for curly, coily, and dry-scalp types; may feel heavy on fine hair. Glass packaging preserves purity but increases fragility risk. Reported occasional dropper leaks in reviews.
