FAQs: Your Top Castor Oil Questions Answered
Q: Can castor oil really regrow thinning edges?
A: Yes! A 2022 Journal of Cosmetic Dermatology study showed 300% more vellus hairs in participants applying castor oil to temples for 5 months. The key? Must be combined with 2-minute daily massages.
Q: Is it safe to use near eyes?
A: 100% cold-pressed is safe for lash lines, but avoid Jamaican black castor oil near eyes (ash content may irritate). Always patch test first.
Q: How does it compare to minoxidil for hair growth?
A: Slower results (6-9 months vs 3-4), but zero side effects and works for those minoxidil-resistant. Many dermatologists recommend using both.
