Rice water, the liquid left behind from soaking the grain, has been making the rounds on the app as a savior for drab locks. Videos featuring the #ricewater tag have garnered more than 642 million collective views, with users saying that it has helped them boost hair growth and revive damaged hair.
Despite the recent surge in popularity, the practice isn't anything new. It actually dates all the way back to the Heian Period (794 to 1185), when Japanese court ladies famously had floor-length hair. It's said that they combed it every day using Yu-Su-Ru, or the rinse water from the washing of rice.
So, should you be adding the ingredient to your hair care regimen? We asked experts to share their thoughts on the trend.
Can you use rice water for hair growth?
From a scientific perspective, there isn’t any research to support the benefits of using rice water on your hair, says Dr. Caren Campbell, a board-certified dermatologist in San Francisco. She pointed to one 2017 study on rice mineral bran extract, which showed that the ingredient may be helpful in preventing hair loss and enhancing hair growth, but she added that it is just one limited study.
That being said, rice water has some other potential benefits. "It has antioxidants, which can theoretically help calm down inflammation on the scalp," says Dr. Robert Finney, a board-certified dermatologist at Entière Dermatology in New York City. "It usually contains the compound inositol, which has anecdotally been shown to increase the growth phase and also decrease friction amongst the hair shafts." It also has amino acids, which can help your strands look firmer and healthier.
The water contains starches, which can also contribute to the appearance of fullness, Finney adds. They create a separation between the hair shafts and as a result, make your mane temporarily look thicker.
Fermented rice water is acidic, so when you rinse your hair with it, it restores and balances the pH of your hair, adds hairstylist Julian Guerrero. "We’ve been seeing hair care brands bring the benefits of rice to hair products, from cleansers to styling creams."
Finney warns that using it too often can cause a protein overload, especially in those with very dry or low-porosity hair, that can lead to further dullness and dryness. So, if your hair falls into those categories, it might not be the best choice for you.
How to make rice water for hair
All you need is a cup of rice — brown long grain or white — to get started. First, you want to rinse the rice to wash off any impurities, says trichologist Jennifer McCowan. Then, combine the rice with three cups of water and let it soak for 24 hours. Strain the water into a jar or container and squeeze out the rice to get as much of the nutrient-packed water as possible, then store in the fridge.
After shampooing, apply your rice water rinse from roots to ends while massaging it in. "Then condition as normal with your regular conditioner," says Guerrero. "Rice water could also be used as a conditioner if mixed with an oil and applied from roots to ends, or just on hair ends, then rinsed and styled."
McCowan echoes the fact that the starches in rice water can make your hair look a bit dull, but she said that pre-made products that contain rice water along with oils, which add lubrication, can help with that.
Not everyone has time to make the concoction themselves, so with that in mind, we found seven rice-infused products that you can add to your beauty cabinet if you want to try the ancient practice.
