Fermented Rice Water for Hair Growth & Strength: How to Make It at Home

You’ve probably seen it trending on TikTok or mentioned in ancient beauty rituals—but is fermented rice water for hair really worth all the hype?

Short answer? Yes.

Longer answer? Only if you do it right.

Let’s walk through how to actually make it (no gimmicks, no moldy jars), why it works, and how a few simple tweaks—like rosemary and apple cider vinegar—take this DIY hair treatment to the next level.

What Is Fermented Rice Water?

Fermented rice water is made by soaking rice in water and allowing it to ferment. During this process, the water becomes rich in vitamins, amino acids, and antioxidants that nourish the scalp, promote hair growth, and strengthen strands.

It’s a time-tested hair treatment used for generations in cultures known for long, healthy, strong hair—and science is finally catching up.

Why Use Fermented Rice Water for Hair?

Here’s what makes this stuff so powerful:

Strengthens hair from root to tip

Encourages faster, thicker hair growth

Smooths and adds shine

Soothes itchy, inflamed, or flaky scalps

Reduces breakage and shedding

But here’s the thing: traditional rice water can stink after fermenting, and if you have hard water, it may not work as well. That’s why I leveled up the recipe.

My Upgraded Fermented Rice Water Method (With Rosemary + ACV)

After a lot of trial and error, this is the only version I’ll make now. Steeping the rosemary first brings out more of its natural oils and scalp-stimulating benefits. Adding apple cider vinegar after fermentation helps with hard water and neutralizes that classic fermented funk.

What You’ll Need:

• ½ cup uncooked white rice (preferably organic)

• 2 cups filtered water

• 1 small sprig of fresh rosemary (or 1 tbsp dried)

• 1 tbsp raw apple cider vinegar (added after fermentation)

• A mason jar or airtight glass container

• A fine mesh strainer or cheesecloth

• Optional: a few drops of essential oil (like peppermint or tea tree)

How to Make It:

1. Rinse the rice thoroughly to remove excess starch and dirt. Set aside.

2. In a small saucepan, bring 1–2 cups of water to a boil. Add your rosemary and reduce to a simmer. Let it steep for about 10–15 minutes, then remove from heat and let it cool completely.

3. Once cooled, use the rosemary water (instead of plain water) to soak your rice. Add the rice and rosemary-infused water to your mason jar.

4. Cover loosely and let it sit at room temperature for 48–72 hours. The longer it sits, the more fermented (and stronger-smelling) it will get.

5. Once fermented, strain out the rice and pour the liquid into a clean spray bottle.

6. Add 1 tablespoon of raw apple cider vinegar to the finished rice water. This helps balance the pH, reduce mineral build-up from hard water, and tone down the smell.

7. Store it in the fridge for up to a week. Shake before each use.

How to Use Fermented Rice Water on Hair:

Use it 1–2 times per week as a final rinse after washing your hair:

• Shampoo and condition as usual

• Pour the rice water slowly over your scalp and hair

• Massage it in for a few minutes

• Let it sit for 5–10 minutes

• Rinse with cool water

Real Talk: Does It Work?

Yes—but like anything natural, consistency is key. After a few weeks of using fermented rice water for hair, I noticed reduced shedding, stronger strands, and more shine. Rosemary helps stimulate the scalp, while apple cider vinegar makes it hard-water-friendly without disrupting the good stuff from fermentation.

Tips:

• Always use filtered water, especially if you live in a hard water area.

• Don’t over-ferment 72 hours is plenty.

• Start with once a week and increase to twice as needed.
