Science, Benefits and Side Effects of Rice Water on Hair

There are numerous cultures that use rice water to get healthy and strong hair. Today let’s understand the science, benefits, and side effects of rice water on hair.

Science of Rice Water for Hair

Hair growth can’t be accelerated using a magical solution. Genetics has a lot to do with it. The good news is that rice water can minimize hair loss and breaking, allowing you to keep more of your hair strands in place to grow.

There are several vitamins, antioxidants, minerals, and proteins found in rice that are advantageous to the development of hair, including Inositol, a rice component, has also been demonstrated to heal damaged hair by penetrating deep into the damaged hair shafts. This results in smoother, shinier hair that is less prone to tangles. Fermentation further enhances the potency of nutrients in the rice water.

As a result of the antioxidants found in rice water, damaged cells are repaired and the scalp is nourished.

The 2010 Scientific Study on Rice Water for Hair

Researchers studied the history of Japanese women’s hair care and styling traditions and discovered a strong connection. Rice water can minimize friction on the skin and enhance hair resilience. To draw unevidenced conclusions, the study, however, relies on historical examples.

The 2012 Scientific Study on Rice Water for Hair

Inositol, a carbohydrate found in rice water, has been shown to heal damaged hair, according to research. When you rinse out the rice water, this inositol remains in your hair, functioning as a barrier and protecting your hair from harm. Even after washing, inositol remains in the hair, providing long-term hair protection.

Note that this research is published directly by an institution that may have economic interests in the outcome of this study.

Rice water’s hair advantages have yet to be demonstrated. Anecdotal data concerning the advantages of rice water for hair need further study.

Benefits of Rice Water for Hair

Rice water is high in vitamins C and B, particularly. Iodine, selenium, zinc, and manganese are some of the trace elements found in it.

Natural hair cleanser

Shampooing your hair with rice water may not be as convenient, but it is free of chemicals and preservatives. You don’t even need to use a conditioner afterward.

Because of its comparable pH levels to the scalp, rice water keeps your hair’s natural oils intact! Some essential oils can be added to rice water to enhance the advantages, and this mixture can be used in place of normal shampoo.

Removes frizzyness of hair

Rice water as a hair treatment has numerous benefits, including increased elasticity, texture, and reduced friction and frizz, according to a 2010 study published in the International Journal of Cosmetic Science. Inositol, a carbohydrate, plays a major role in this phenomenon.

Hair Growth

If you wish to decrease hair loss and promote hair growth, rice water is ideal. The amino acids in it aid in hair regeneration and promote quicker hair growth.

Prevents premature greying of hair

Antioxidants in rice water help reverse hair aging and stimulate cell regeneration from the inside out by reducing free radical damage. As a result, it is better equipped to combat dust and pollution-related environmental harm.

Detangles hair

Rice water’s smooth texture, which is rich in vitamins, soothes and detangles your hair, making it simpler to brush and detangle without causing damage.

Source of Pitera

Fermenting rice water increases its vitamin and nutritional content, which feeds your hair follicles and helps them grow. Healthy hair growth is promoted, as well as an enhancement in hair quality.

When the rice water is fermented, an organic acid called ‘pitera’ develops in the rice water, which is rich in vitamins and minerals as well as amino acids. As a cell regenerator, pitera is proven to maintain your skin and hair healthy.

Side Effects of Rice Water on Hair

Recent years have seen a rise in the popularity of using rice water to cure hair for a number of different reasons. As a natural product, rice water isn’t to be taken for granted.

When you consider that it’s produced with simple components like rice and water, it appears to be fairly safe for most individuals to use.

Because it’s typically non-irritating, it’s appropriate for individuals with sensitive scalps and skin, as well as those with allergies. Those with rice allergies, on the other hand, maybe irritated by it.

If you have a known rice allergy, avoid using anything that contains this component.

Use a tiny quantity at first to see how you respond to it. As you see benefits, you may progressively increase the amount you’re using.

To avoid adverse effects, discontinue using this component if you experience itchiness, irritation or increased dryness after using it. Yeast growth or an allergy might be the cause of your poor response.

Dry Scalp

Although rice water is effective in treating scalps, many people have reported positive outcomes. There are others who think it should be used more often and/or left on for a longer period of time when dealing with more severe instances. It’s even been reported that some people don’t rinse their hair at all, or leave it on overnight.

The truth is that your hair will absorb all of the advantages of rice water within the first half-hour. Your hair roots and scalp will then be subjected to undesirable chemical reactions, which may not end well.

Please keep in mind the overproduction of yeast in the system might cause a dry, flaky scalp. Over time, the starch and sugars in rice will exacerbate the situation.

You should definitely restrict yourself to two treatments per week if you suffer from severe dry scalp or dandruff. Perhaps you could try using it more regularly if it is working well.

May contain Arsenic

Rice water may not always include arsenic, although it does in some areas.

Rice is commonly cultivated in old cotton fields in the United States. Those cotton fields used to be treated with arsenic-based pesticides. When the rice is soaked in water that contains pesticide residues, it feeds the rice. Due to some mysterious reason, brown rice seems to absorb more of it than white rice, perhaps by approximately two times as much as white rice does.

As a result, you’ll have to rely on your own judgment when it comes to these tiny quantities. If you’d want to limit your exposure, you can use Basmati rice in place of regular rice. Basmati rice gets imported from nations such as Pakistan and India, where arsenic isn’t an issue. You can also look for a natural rice water hair product from a trustworthy company and is the best way to prevent this from happening in the first place. In order to avoid these unpleasant side effects, organic rice water products are developed for natural hair.

Too much Protein

It’s safe to say that rice water includes a fair quantity of protein. Most folks won’t have an issue with this. But if you have low porosity hair, it could become a problem in the long run. As a result, they will stick to your hair instead of absorbing the proteins in low-porous hair.

For those with high porosity hair, the protein will simply be absorbed by the hair, making it stronger and healthier. When it comes down to it, if you do run into that small snag,

This protein attachment to your hair can prevent other hair treatments from entering the follicles, resulting in hair loss. As a result, certain hair products are rendered essentially worthless. As time passes, the proteins grow more rigid, which might result in brittle and dry hair

You may still use rice water on your hair, but you have to be careful about how much you use. Because of this, the key to success when using a protein treatment on hair with low porosity is moderation.

Use rice water as a conditioner once or twice a week instead of every day and observe how your hair responds. If you want to obtain the greatest results from your curly hair treatment, you’ll need to experiment.

Smells funny

Fermented rice water is highly recommended by many individuals, and there are a number of pro-beauty products that include it. Fermented rice water may have some extra benefits, but it also has a unique strong fragrance.

Especially if you are one of those individuals who like to keep it on their hair for lengthy periods of time, this might be an issue. Using fermented rice water might also cause your hair to become stiff and hard, which is definitely not what you were aiming for!

Try adding a few drops of your favorite essential oil to your rice water combination to help cover the odor, but the results may vary. Always keep in mind that chemistry is based on ratios and proportions. Even if you add too little, you’ll still get a strong odor. As a result of adding too much, you may wind up with an overpowering smell that is no different from the original aroma.

Too much essential oil might also hinder other nutrients from entering your hair follicles. Always keep in mind that the nutrients you want your hair to receive are all carried and absorbed by water. If the oil attaches to your hair, it makes it difficult to absorb it into your body.

The smell of fermented rice water may be avoided by keeping your rice water treatment cool and utilizing it as soon as possible.

History of Rice Water on Hair

Hair strengthening and beautification using rice water is nothing new. When the Heian period began in Japan, court ladies were renowned for their long, flowing hair that hung to the floor. Rice water was the key to success for them.

When these ladies washed their hair and face some 1,200 years ago, they utilized rice water to clean their hair. When they bathed in rice water, they maintained their long hair healthy.

After Huangluo in China made the Guinness Book of Records the ‘world’s longest hair village’, rice water’s use became popular. As a regular face toner and hair rinse, Chinese ladies have used unpolished rice water since the dawn of time.

A remarkable aspect of the Yao women from Huangluo Village in Guangxi Province in southern China is their extremely long hair, which remains black until they are approximately 80 years old, according to a new study. “World’s Longest Hair Village” is a Guinness World Record for Yao women with an average hair length of around 6 feet. They wash their hair with fermented rice water, which contributes to their long hair.

Because they bathe in rice water, the Yao women attribute their hair’s length and color to the fact that they bathe in rice water.

Many beauty advice sites, as well as cosmetic manufacturers, have taken note of these practices in recent years. As a result, the rice water craze is now sweeping the nation.


It’s not uncommon for those who are tired of having short hair to search for a quick cure to get their hair to a longer length. Unfortunately, a quick fix like this doesn’t exist. There is no substance or mixture that can help you grow inches in only a few days, not even rice water.

In recent years, rice water has been touted as a miraculous cure for hair development, but while it has its advantages, there is no scientific evidence that rice water can truly make your hair grow. As a way to separate reality from fantasy when it comes to the use of rice water for hair growth.

There is a lot of anecdotal evidence concerning rice water and hair development. Genetics is what decides how fast your hair will grow, but it doesn’t imply rice water is completely ineffective in this regard. In addition, it can help your hair grow by providing it with the nutrients that it needs.

Keeping an open mind is crucial as what works for one person may not work for another. In addition to hair texture, type, and lifestyle, rice water’s effects can also be affected by a person’s genetics and hairstyling habits.

Rice water can have some negative effects on hair, but they are generally mild and won’t be an issue for everyone. Some negative effects can be avoided if you are attentive and learn how to use rice water for hair properly. Begin using a natural rice water hair product. Let your hair be your guide, but don’t be afraid to experiment with rice water. You could even discover a new hair treatment that you love!

You should consult a dermatologist or a trichologist if your major worry is hair growth.


Can I use rice water every day on my hair?

Use rice water as a conditioner once or twice a week instead of every day and observe how your hair responds. If you want to obtain the greatest results from your curly hair treatment, you’ll need to experiment.

How long can I keep rice water in my hair?

As a hair mask, rice water can be applied overnight. Please note that rice water has the potential to develop germs, which can lead to itchiness and peeling on the scalp if left on for more than 18 hours.
