kate blanc cosmetics castor oil

We’ve never been more thankful for a beauty trend than thick, bushy eyebrows. We cringe at all the tweezing and waxing it took the achieve the pencil-thin lines of the 2000s and have learned to embrace our natural shape thanks to Cara Delevingne, Lily Collins and Olivia Culpo. But sadly, because of all that plucking and grooming, our brows have become a patchy, sparse version of our childhood arches.

We could chock it up to a loss and work our pencils, pomades, powders and gels to fill in the gaps. But there’s another solution that involves zero makeup skills—oh, and it’s under $10.

We’d like to introduce you to our good friend, castor oil. It’s packed with essential fatty acids, like omega-6 and omega-9, which help to promote hair growth. Here’s how to use it: Dip a clean spoolie in the oil and brush it through your brows before bed. The nutrients will get to work while you snooze, helping to fill in and grow out sparse brows. (And while you’re at it, swipe some on your lash line for stronger, fuller eyelashes.)

Cue the Amazon search. To our delight, we stumbled upon a total gem. Certified USDA Organic Kate Blanc Cosmetics Castor Oil not only has almost 4,000 positive reviews, it also comes with a spoolie and tiny brush. At just under $10 a bottle, it costs almost half as much as our go-to brow products and is six times less expensive than our favorite lash serums. Get in there quickly, because we just might buy the whole lot.
