What Is Castor Oil?

“Castor oilis a vegetable oil pressed from castor beans,” says trichologist Gretchen Friese.

Not a single one mentions anything to do with hair growth.

But some people swear by the stuff for gettingbold, bushy browsor long, luscious lashes.

So, what’s the truth?

Friese says castor oil “has been used for years to treat various conditions, includinghair loss.

Does Castor Oil Work For Brow Growth?

“Currently there is no real evidence that castor oil affects eyebrow growth,” says Friese.

“But there is no scientific evidence showing that castor oil stimulates hair growth.”

“There are plenty of anecdotal stories, but there is no scientific evidence.”

“Think of it more as good maintenance for your brows.

I think it’s all about setting expectations here.”

How to Apply Castor Oil to Brows

Castor oil can be used daily, according to Friese.

Also, only pure castor oil should be used for this purpose.

“verify your eyebrows are clean and free of makeup.

Avoid contact with eyes,” recommends Friese.
