Rice water, not rice protein itself, is used as a hair treatment. It contains amino acids and other nutrients beneficial for hair health. You don't extract pure rice protein for a hair treatment; instead, you utilize the water leftover after rinsing rice. This water is rich in nutrients that can improve hair strength, shine, and potentially growth.
Making Rice Water for Hair
Here's how to make rice water for a DIY hair treatment:
-
Rinse the Rice: Start with ½ cup of uncooked rice (as suggested by CNN Underscored). Rinse the rice thoroughly under running water to remove any excess starch or debris.
-
Soak the Rice: Place the rinsed rice in a bowl with 3 cups of water. Let it soak for at least 30 minutes, or even longer (up to overnight, as some sources suggest). The longer the soak, the more concentrated the nutrients will be in the resulting water.
-
Strain the Water: Gently strain the rice water through a fine-mesh sieve or cheesecloth into a clean bottle. Avoid squeezing the rice, as this can introduce unwanted particles into the liquid.
-
Store and Use: Store the rice water in the refrigerator for up to 4 days (r/AsianBeauty). Apply it to your hair as a rinse or leave-in conditioner. You can spray it on once a week ([source from 27-Feb-2022]).
Important Considerations:
-
Protein Overload: Be mindful of protein overload. Too much protein can make hair brittle and dry (r/Haircare, r/curlyhair). Start with infrequent use and monitor your hair's response.
-
Fermented Rice Water: Some people ferment their rice water for enhanced benefits. This involves letting the rice water sit at room temperature for a few days before use. However, this method requires careful monitoring to prevent spoilage.
-
Not a Guaranteed Growth Solution: While rice water may contribute to healthier-looking hair, it's not a guaranteed solution for hair growth (Quora). Its benefits primarily focus on shine, strength, and improved manageability.
