The speaker discusses the rice water method, a traditional Chinese technique for hair care, and shares her extensive research on the subject. She explains that the method was first recorded in the Han period, where Japanese women used rice water to rinse their hair, keeping it strong, shiny, and black. The speaker also mentions that the method is still used by the Red Cow women of China, who credit it for their hair's health.
The speaker then delves into the science behind the method, explaining that the starch in rice water helps heal damaged skin, and the hair benefits come from the nutrients in rice, including amino acids, minerals, antioxidants, selenium, magnesium, folic acids, vitamins B1 to B6, C and E, niacin, vitamin K, and inositol.
She provides a step-by-step guide on how to make the rice water mixture, emphasizing the importance of using plain white rice and not leaving the mixture in a jar overnight. She also shares her experience applying the mixture to her hair, noting that it felt like a watery conditioner. She mentions that the mixture should be rinsed out within 20 to 30 minutes to avoid protein overload, which can lead to brittle hair and breakage.
The speaker concludes by advising viewers to use the method sparingly and to dilute the mixture with water if they are worried about the protein content. She also encourages viewers to try the method and see if it works for their hair type.
