Beauty vlogger Farah Dhukai has posted a beauty hack that'll rid your scalp of dandruff with a product found laying on top of most bathroom sinks: mouthwash.
Wait... what? Yep. Best part is, it's a mere three-step process.
Step 1: Fill a spray bottle with half Listerine — or any other mouthwash — and half water, and give it a shake!
Step 2: After a normal shampoo and conditioner wash, spray the mixture onto your scalp.
Step 3: Let it sit for a few minutes, then wash out with water. Voilà!
This tip isn't entirely new.
And it's hardly the first bizarre hair hack.
But does it work?
"This seriously works!" one user commented in response to Dhukai's Instagram post. "Tried this on my daughter. It worked thank you," another said.
While the social media users were quick to comment about the might powers of the mouthwash, Dr. Bessam Farjo, a hair transplant surgeon and medical director of the Institute of Trichologists, is not so convinced.
In a phone interview, Dr. Farjo explained that Listerine could help mild cases of dandruff because it is an antiseptic. However, the product isn't as strong as, say, dandruff shampoos, and would not make a significant difference. He also cautioned that, because the product is meant for the mouth, it will sting those with sensitive skin when it is applied to the scalp.
If you decide to try it, you might want to apply another hair product after trying this tip because you'll likely end up smelling like you doused yourself in a big ole bottle of mint-scented perfume.
