Abstract

pp.29–33 We researched the histories of the hairstyles and hair care practices of Japanese women, and found a very close relationship between the two. For example, the court ladies of the Heian Period, whose beautiful long hair, called suberakashi, reached to the floor, were said to have combed their hair each day using Yu-Su-Ru (rinse water obtained from the washing of rice) . Rice is considered to be the most important food in the Japanese diet, and the historical fact that rice was used for hair care is very interesting. We therefore focused our attention on the Yu-Su-Ru hair care practice in the Heian Period, and examined its effects on hair. As a result, we found that Yu-Su-Ru exhibited hair care effects, such as reducing surface friction and increasing hair elasticity. However, when hair was treated with Yu-Su-Ru alone, flaking was observed on the hair surface, and the direct application of Yu-Su-Ru was considered difficult. Thus, Yu-Su-Ru extracts, which are highly effective in hair care and do not cause flaking were examined. The results showed that Yu-Su-Ru extracts had multiple functions for hair care at the same time. Thus, the new application of Yu-Su-Ru for hair care was discovered.

... Rice is used in several traditional Asian treatments for cardiovascular disease, diabetes, inflammation, and as a skin and hair treatment [12][13][14]. Historically, rice water obtained from the washing of rice has been used for traditional hair treatment in Asia, including Thailand, because it exhibits effects on hair, such as reducing surface friction, increasing hair elasticity, and inducing hair growth [15]. According to these traditional Asian wisdoms for hair care, Thai pigmented rice containing proanthocyanidin is one of the important natural sources of active ingredients for hair-growth promoting product. ...

The hair growth-promoting activities of Thai native red (Sang-Yod-SY and Mun-Poo-MP) and black (Black glutinous-BG and Hom-Nil-HN) pigmented rice (Oryza sativa L.) extracts, including in vitro 5α-reductase inhibition, hair growth-promoting activity on human hair germinal matrix cells, and in vivo hair-cycle-converting activity in C3H/HeMlac mice, were investigated. Moreover, these extracts were determined to be safe via cytotoxicity (HaCaT cell) and in vivo irritation tests. The results showed that SY red rice extract with high contents of proanthocyanidin (1.50 ± 0.16 mgECE/g extract) exhibited significantly higher 5α-reductase inhibitory activity (18.5 ± 9.0 mgFEA/g extract) (p < 0.05). The maximum growth-promoting activity for human matrix cells treated with SY extract reached about 216.2 ± 0.7% (1 mg/mL) relative to control (100%) after 3 days culture (p < 0.05). Moreover, topical application of 1 mg/mL SY red pericarp rice extracts on shaven C3H skin in telogen phase led to significant hair regeneration (97.2 ±1.3%) based on the shaven area, while vehicle application only tended to yield a regeneration of 50.9 ± 11.7%. Red rice extracts were found to be safe, without signs of cytotoxicity and irritation. This research demonstrates the health benefits and safety of SY red pericarp extract when used for hair growing activity and its potential for use as a natural hair growth promoter and 5α-reductase inhibitor.
... Unbeknownst to most households, rice water contains numerous vitamins and minerals. With its natural content, rice water has been applied and infused to different fields, such as in cosmetics formulation (Marto et al., 2018), hair treatment (Inamasu et al., 2010), and skin treatment (Morse, 2019). ...

Rice water has been widely produced in households as a result of cooking rice. Oftentimes, rice water is discarded, wasting water from which the existing issue of water scarcity is still prevalent in several countries. This paper aims to describe the effect of using rice water as a watering agent, thereby recycling and reusing water. Twenty in tnine plant samples were observed and collected data from. One-way ANOVA analysis on the plant samples data was performed. The analysis showed a significant difference between the means of the treatments’ absolute growth rate (AGR) with rice water treatment having the highest average AGR (p = 0.018). Samples’ observations comparison were done still with rice water, having the highest fresh and dry weight, and height. These results indicate that usage of rice water on plants has the greatest growth performance when compared to the two treatments, tap and distilled water. Hence, rice water on plants is a good and effective choice to use when watering plants.

The skin healing benefits of rice have been known for centuries. Rice is the cuticle existing between the rice and the husk of the paddy and consists of embryo and endosperm of the seeds of Oryza sativa, family Graminae. Rice water is a food processing waste that can potentially be incorporated into cosmetic formulations. However, no scientific evidence supports their role in skincare products. The aim of this project is to design and develop a formulation containing rice water and to evaluate its biological properties, namely, the anti-aging and antioxidant rice water properties Rice water presented in vitrobiological antioxidant activity and elastase inhibitory effect. The formulation containing 96% rice water was biocompatible with the human skin and presented suitable cosmetic properties. Rice water should be thus considered as an anti-aging ingredient to be used as raw material for skincare applications. They are useful for the hair shine, smooth, Lustre, hairStrength, also use as chemical free hair cleanser and maintain the pH of the scalp. Another important reason to use rice water for hair is the fact that it helps hair growth, and you can see the increase in a short span itself. As the rice water helps protect the hair from damage, the hair remains healthy. The protein boost that the rice water gives to the hair helps it grow fast.

Background: Rice has been used for cosmetic purposes for centuries and its benefits have been translated into modern-day skin careproducts. Methods: Pubmed and google were searched with the terms "skin care" and "cosmetics" in conjunction with the words "rice", "rice bran", and "fermented rice bran". Resulting articles were analysed for potential benefits of ingredients contained within rice for skin care and summarised. Results: Individual components of rice have been identified including phenolic compounds, betaine, squalene, tricin, and rice bran. These rice-derived ingredients have been found to be antiaging, anti-inflammatory, whitening, photoprotective, and moisturizing. Moreover, rice-derived ingredients have demonstrated benefits for dermatological conditions. Rice bran ash extract increases melanin synthesis and offers protection from radiation and skin injury. Fermented rice bran extract and rice bran broth baths have shown utility in atopic dermatitis treatments. Literature suggests that rice-derived ingredients are also safe, non-irritating, and hypoallergenic. Conclusion: Ingredients isolated from rice and its components have wide potential for use in skin care and cosmetic products.
