Customers say it helps strands “grow tremendously.”

I may never be a prima ballerina — I let those hopes and dreams go when I discovered I can’t even do a single pirouette without toppling over. But I can still attempt the ever-so-chic, slicked back ballerina bun. Apparently I’m not alone, since Hailey Bieber recently took to TikTok to do just that. I can’t lie, though, when I say the product she used to create the look definitely surprised me.

In the video, Bieber held up Pura D’or’s Organic Castor Oil, which she then used to slick back her strands and give them a glossy, shiny finish. If the brand name sounds familiar to you, that’s because Pura D’Or is behind one of Amazon’s most popular hair growth shampoos — and of course its castor oil is just as popular with more than 7,000 five-star ratings. And did we mention it’s just $15?

When it comes to the Pura D’or castor oil, there are multiple benefits to be had, including hair growth, which is what many Amazon shoppers use it for. The 100 percent pure oil nourishes and conditions follicles to encourage eyelash, eyebrow, and hair growth thanks to its "fatty acid component… which is ricinoleic acid” and “can lead to blood vessel dilation," board-certified cosmetic dermatologist Dr. DiAnne Davis previously told InStyle. "When this happens on the scalp, increased blood vessel dilation will increase blood flow to the hair follicles." The rich, occlusive oil can also help moisturize the follicles and promote hydration.

One reviewer who lost their lashes after removing extensions raved that not only did they come back “long and full” within two weeks, but that after using the Pura D’Or on their scalp and roots, it made their hair “grow tremendously.” Other reviewers say the moisturizing oil makes hair “so smooth and shiny,” thicker, and “full of life.” One shopper with baby fine hair used the castor oil as a mask every two weeks and said their hair is “growing faster,” while another noted it helped their hair “grow in spots that there was no hair” before.

Slicked ballerina bun à la Bieber aside, how could you not want to incorporate the Pura D’or Organic Castor Oil into your hair routine after those rave reviews? I know I’ll be adding this to cart immediately — if for no other reason than I can practice my pirouettes.
