Japanese Rice Water: The Ancient Secret Behind Viral Hair Growth Trends

What Exactly Is Rice Water?

Rice water is the starchy water left over after soaking or boiling rice. It contains inositol, amino acids, vitamins B and E, and antioxidants that nourish the hair shaft, repair damage, and promote growth. When fermented, it becomes even more potent, creating a powerful scalp treatment that’s as natural as it gets.

Benefits of Using Rice Water for Hair

  • Stimulates Hair Growth: Inositol boosts circulation and supports longer, thicker strands.
  • Improves Shine: Rice water smooths the cuticle, reducing frizz and adding luster.
  • Strengthens Roots: Rich in amino acids that fortify from root to tip.
  • Soothes the Scalp: Its anti-inflammatory properties reduce dandruff and irritation.

How to Make Rice Water at Home

  1. Rinse 1/2 cup of white or jasmine rice to remove impurities.
  2. Soak in 2–3 cups of water for 30 minutes or let it ferment for 24 hours for a stronger effect.
  3. Strain the water and store in a spray bottle.
  4. Use 1–2 times per week as a scalp and hair rinse. Leave on for 10–20 minutes before rinsing out.

Products Featuring Rice Water

  • Yao Secret Rice Water Shampoo Bar: Inspired by the long-haired women of the Yao tribe in China.
  • Innisfree My Hair Recipe Strength Treatment: A Korean favorite enriched with rice protein.

Is Rice Water for Everyone?

Rice water works for most hair types, especially straight to wavy. Curly and coily textures may require dilution or mixing with conditioner to avoid protein overload. Always patch test and start slowly to see how your scalp and strands respond.
