We don't have to lay out why brows are arguably one of the biggest beauty concerns—the shape of your brows define your face and determine the direction of what your beauty look is going to consist of. It's no shock to us that when something promises to help them grow thicker and faster that people are all for it.
When you google "castor oil to grow eyebrows," this is what you find:
"Heavy tweezing, waxing, and shaving can sometimes lead to a permanently thinned-out brow. Castor oil helps reverse this by encouraging hair growth from the follicles that have become dormant," according to an article on Stylecraze.
"When we apply them to lashes and eyebrows, all these factors contribute to stimulating blood circulation in skin, especially around the eyes. This will indirectly improve the hair growth," according to an article on Good Health Academy.
But are these claims actually true? Is this the all-natural miracle brow potion that we've all been waiting for? We asked experts ourselves and did a little digging.
"Castor oil is filled with vitamins that our hair and skin need to support itself," says Sabah Feroz, brow expert at Blink Brow Bar."It is high in omega-6 fatty acids, vitamin E, and many other beneficial minerals that moisturize and support healthy hair growth."
"Castor oil is a triglyceride fatty acid from the beans of the castor bean plant," Jamé Heskett, holistic doctor and author of The Well Path, said to us. "It's a unique TGFA called ricinoleic acid, which is fairly rare in the plant kingdom."
But when asking her about the benefits of the oil, she listed the following: improves circulation; stimulates the lymphatic system; works to kill fungi, inflammation, and dermatitis; heals acne and injuries by reducing the bacteria and healing wounds; reduces cellulite; and acts as a powerful emollient. Not a single one mentions anything to do with hair growth.
In an online article published in Marie Claire, Sherri Soliman recounted a time where she actually lost hair when she used castor oil to grow her brows out. It wasn't just a few hairs either. "The next day, a few hairs fell out, which was a little unsettling, but no big deal," she wrote. "But then, the problem quickly worsened until it became uncontrollable—I was easily losing more than 100 hairs per day. As I woke up each morning to find new hairs dangling loosely from my brow bones, there would be occasions when entire sections went missing, sometimes the tail, other times the arch or the head."
She asked Joshua Zeichner, MD, dermatologist and director of cosmetic and clinical research in dermatology at Mt. Sinai Hospital in New York City, for his input, and he said that oftentimes natural preservatives can easily cause skin irritation just as much or even worse than parabens. "Just because something is natural doesn't mean it's without side effects," he told her.
As we know, we can't take any beauty trend that has these bold claims for face value when found on Pinterest. While castor oil may have great skin benefits, it doesn't look like it's the end of our search for a miracle brow grower. So if you're still on the fence about whether to use castor oil, Ferox suggests trying almond oil instead.
"What many people do not know is that almond oil has the same properties as castor oil in terms of moisturizing brow hair. While I do like castor oil, my favorite product is BBB London Nourishing Brow and Lash Oil," she says. "These products are so easy to use and apply. They include lavender, rosemary, and sweet almond. Rosemary and almond oil stimulate hair growth, while lavender soothes and hydrates the skin. I use it every night it and my lashes look longer and my brows look fuller."
