Handcraft Blends Castor Oil for Eyebrows & Eyelashes: Does It Really Work?

By HandcraftReview Team · Updated March 2026 · 8 min read

Handcraft Blends Organic Castor Oil 16oz

Castor oil for eyebrows is one of the most searched beauty topics on Google — and Handcraft Blends Organic Castor Oil is the #1 bestseller in its category on Amazon with over 8,500 reviews. We tested it for six weeks. Here is exactly what happened.

This is USDA certified organic, cold-pressed, expeller-pressed, and hexane-free. That last point matters: hexane is a petroleum solvent sometimes used to extract oils cheaply, and you do not want that anywhere near your eyes.

What the science says

Castor oil is roughly 90% ricinoleic acid, an unusual omega-9 fatty acid with documented anti-inflammatory properties. While no large-scale clinical trials exist specifically for eyebrow regrowth, ricinoleic acid is believed to support hair follicle health by improving scalp circulation and reducing prostaglandin D2 — a compound associated with hair loss.

Realistic expectation: Castor oil conditions existing hairs and may stimulate dormant follicles. It will not regrow brows where follicles are permanently damaged, but most users with over-plucked or naturally sparse brows see meaningful improvement in 4–8 weeks.

Our 6-week results

Week	Observation	What to do
1–2	No visible growth yet. Hairs feel softer and less brittle.	Apply every night, be patient
3–4	Area looks slightly fuller. Fine baby hairs visible at the edges.	Continue nightly, do not skip
5–6	Noticeably thicker and more even. Sparse patches filled in slightly.	Can reduce to 4–5x per week

How to apply: step-by-step

1. Cleanse first. Remove all makeup and oil from the brow area. Castor oil absorbs best on clean skin.

2. Use a clean spoolie. Dip the tip into the oil and tap off the excess. Less is more — this oil is thick.

3. Apply with the hair growth direction. Work from the inner corner outward using short, light strokes along the brow bone.

4. Leave on overnight. Rinse off in the morning with your regular cleanser. Do not rinse immediately — the oil needs time to absorb.

Safety note: Keep away from the inside of the eye. Apply to the brow bone and lash line only. Discontinue if any irritation occurs.
