Rice water is the starchy liquid produced by soaking or cooking rice. It is often touted as a simple home remedy to encourage hair growth and make it more voluminous and shinier. There is some evidence to suggest that rice water can help with hair growth, and it is also believed to help improve nail strength. However, some sources argue that water is one of the worst chemicals for nails as it can penetrate through the layers of keratin and push them apart, causing peeling. This has led some to suggest that oil treatments may be more beneficial for nail health.

Rice water for nail strength
Rice water has become a popular beauty trend, with many people advocating for its ability to enhance hair growth, reduce tangles, and improve shine and volume. While there is some scientific backing to these claims, the evidence for rice water's effectiveness in promoting nail strength is less clear.
Rice water is the starchy liquid produced by soaking or cooking rice. It is rich in antioxidants, amino acids, and minerals such as vitamin A, B, C, and E, as well as inositol. These nutrients are known to promote hair growth and strengthen the hair shaft. The protein in rice water is believed to contribute to the overall strength and health of hair.
Some people have suggested that if rice water can improve hair health, it may also be beneficial for nail health. However, it is important to note that nails and hair have different structural compositions and react differently to external factors. While rice water may provide benefits to hair due to its ability to reduce friction and increase elasticity, these effects may not translate directly to nail care.
In fact, some sources suggest that water can be detrimental to nail health. Nails are very porous, and water can penetrate through the layers of keratin, pushing them apart and leading to peeling or delamination. This is the opposite of the desired effect when trying to grow strong, healthy nails. Instead, well-oiled nails can help repel water and prevent this issue. Oils such as jojoba oil can penetrate the layers of keratin and help keep them bonded together.
While there is limited information specifically about the effects of rice water on nail strength, some individuals have reported stronger nails as a result of taking hair/skin/nail supplements and prenatal vitamins, which may include rice water as an ingredient. However, without more targeted research, it is difficult to attribute any improvements in nail strength solely to rice water.

Rice water for hair growth
Rice water has been used for centuries in China and Japan to grow hair longer, prevent it from turning grey, and keep it tangle-free. It is the starchy water left over after rice is cooked or soaked. Rice water contains vitamins, minerals, and an antioxidant called inositol, which is said to promote hair growth.
There is some anecdotal evidence that rice water improves hair strength, texture, and growth. Some people report that their hair grew faster after using rice water, but it is difficult to determine whether this was due to the rice water or other factors, such as increased overall hair care.
A 2010 paper suggests there may be a scientific basis for the claims that rice water promotes hair growth. The authors note that rice water may reduce surface friction and increase hair elasticity. However, the study relies on historical examples to draw conclusions, and more research is needed to prove the benefits of using rice water.
A 2022 systematic review of 10 studies found that products containing rice bran showed promise for hair growth. Rice bran may increase the production of growth factors and signals that help cells grow during the active hair growth phase, and it may also slow down the enzymes that cause hair to stop growing and enter a resting phase. However, this review did not specifically examine the effects of rice water on hair.
While there is limited scientific research to support the use of rice water for hair growth, some people find it beneficial as a hair treatment. It is thought to act as a conditioner, making hair smoother and shinier, and improving hair strength, which may help promote hair growth.
To use rice water, you can rinse your roots after conditioning and let it air dry, or you can apply it overnight. You can also seek out products containing inositol, the carbohydrate responsible for rice water's reparative properties, for similar results.

Fermented rice water
To make fermented rice water, you can save the water from cooked rice or soak rice in water for 30 minutes to 24 hours and use that water. This water absorbs the vitamins and minerals from the rice. Fermented rice water can be used topically for hair growth, as a skin toner, or even consumed orally, with reports of numerous health benefits.
Some people have reported that using fermented rice water has resulted in a lot of new hair growth and faster hair growth rates. It has also been used to improve lash length and growth. Fermented rice water contains B vitamins, which are necessary for melanin production and may help prevent grey hair.
Overall, fermented rice water is a simple and inexpensive treatment that has been reported to have various benefits for hair, skin, and nail health.

Rice water safety concerns
Rice water is the starchy liquid produced by soaking or cooking rice. It has been used as a traditional Asian hair care practice and is purported to enhance hair growth, thickness, shine, and volume.
While rice water has been anecdotally linked to various health and cosmetic benefits, there are several safety concerns associated with its use, especially regarding ingestion:
Microbiological and Chemical Safety Risks
Unwashed and uncooked rice water may contain harmful microorganisms and chemicals. Raw rice can carry bacterial spores, such as Bacillus cereus, along with residues from pesticides, herbicides, and arsenic. Arsenic, a toxic element, is a particular concern in rice due to the way it is cultivated in continually flooded paddies, which increases its absorption of arsenic from the soil. This risk is heightened in certain regions with higher levels of arsenic in the water or soil, such as South Asia.
Carbohydrate Content
Rice water is likely to be high in carbohydrates, and excessive consumption of carbohydrates can be counterproductive to certain health goals, such as weight loss.
Nail Health
While rice water is primarily associated with hair care, some people have explored using it for nail care. However, water is one of the worst chemicals for nails as it can penetrate the layers of keratin and cause peeling. Therefore, using rice water on nails may have adverse effects and weaken them.
Skin Irritation
Some individuals have reported that using rice water on their hair caused flaking, which could indicate skin irritation.
Heavy Metal Contamination
Rice, especially that grown in certain regions like Hunan in China, can be exposed to heavy metal contamination during cultivation. This includes exposure to lead, mercury, cadmium, chromium, and arsenic through industrial wastewater pollution and excessive fertiliser use.
It is important to note that the safety profile of rice water may differ depending on whether it is used topically or ingested, and further research is needed to comprehensively understand its potential benefits and risks.

Alternatives to rice water
While some people have reported success in using rice water to improve their nail health, there are several alternatives that can be used instead.
Firstly, it is important to note that water is generally considered to have a negative impact on nail health. Nails are porous, and water can penetrate the layers of keratin, causing them to separate and peel. Therefore, it is recommended to avoid soaking nails in water for prolonged periods.
One alternative to rice water is the use of oils, such as jojoba oil or argan oil. These oils can help to repel water and keep the layers of keratin bonded together, preventing peeling and strengthening the nails. Oil soaks are a popular method for improving nail health and can be done as often as desired, with once a week being a suggested frequency.
Additionally, collagen supplements have been reported to strengthen nails. One individual reported that collagen powder helped make their nails stronger, although they did not notice a significant improvement in their hair. Biotin supplements and prenatal vitamins have also been suggested as potential alternatives, although the effects on nail growth may vary.
Castor oil is another option that has been recommended for lash growth, although consistent use is key. It is important to note that individual experiences may vary, and what works for one person may not work for another. It is always a good idea to consult with a healthcare professional or a dermatologist before starting any new supplement or treatment.
