According to Amazon shoppers, this Pure Body Naturals Castor Oil will naturally grow out perfectly fluffy brows and lashes — and it's now just $9 ahead of Amazon Prime Day 2022. The oil is naturally rich in vitamin E, minerals, and fatty acids, which according to the brand, promote the growth of both brows and lashes, repair skin tissue, and keep it hydrated — claims that have been confirmed by thousands of Amazon shoppers who say they've seen "exponential growth" with use. It's also organic, vegan, cruelty-free, and doesn't contain parabens, phthalates, or fragrance. Courtesy Shop now: $9 (Originally $16); amazon.com Many shoppers say they use the castor oil daily and "started seeing new growth after a week" of use, reporting thicker and fuller lashes and brows. "After a month, I saw dramatic results," said the same customer. "I started seeing growth and thickness within a week of using it," another shopper confirmed. "Now two months later, my lashes are thicker and longer than they have ever been!" And a third reviewer said, "After using the castor oil, my eyebrows have been growing like crazy (my eyebrows usually grow slowly)," adding that their "eyelashes are growing as well." And while this kit is meant for eyebrow- and lash-growth, reviewers say the castor oil can be used for various purposes, including as a hair conditioner, growth-booster, and full-body moisturizer. "I personally like to mix it with beeswax and charcoal to create a safe, homemade mascara," another shopper said. This castor oil comes in a convenient kit with supplies to apply the oil to both your brows and eyelashes. With it, you'll receive five wands, five spoolies, and a glass dropper, which shoppers say helps them to "be very precise" while applying. For fuller, thicker, and healthier brows and lashes, shop the Pure Body Naturals Castor Oil on Amazon for $9.
