Thicker, fuller hair doesn’t start in a lab — it often begins in your kitchen with natural ingredients and a healthy diet. While you may think that the store-bought shampoo is healthy and “natural” because it has a picture of grapefruit on it or smells like mint, you’d be sorely mistaken.

If you’ve noticed more strands in the shower drain or your ponytail feels thinner than it used to, you’re not alone. Your hair is deeply personal. The good news? You can support it in powerful, practical ways, including learning how to make nourishing shampoo at home with natural ingredients that heal your scalp and encourage growth. 

What Your Hair Actually Needs to Grow Thicker

Hair growth isn’t random. Each strand grows from a follicle, a complex miniorgan that works with oil glands, muscles and skin cells to make the hair shaft. You have around 100,000 follicles or hairs on your scalp alone. Every one of them responds to internal and external signals. 

Healthy locks depend on the following:

• Strong circulation to the scalp
• Balanced oil production
• Low inflammation 
• Vitamin B3 or niacinamide intake for skin and hair repair
• Adequate nutrients, such as iron, vitamin D, zinc and protein

Oxidative stress — an imbalance between free radicals and antioxidants — disrupts this process. A recent review identified oxidative stress as a major mediator in several types of hair loss. Chronic inflammation, poor diet, high sugar intake and even excess alcohol increase that burden.

However, increasing your intake of vitamin D and iron helps your body fight off alopecia. While nutrition doesn’t override genetics, what you eat can influence how those genes are expressed. Your shampoo may not fix a deficiency, but it can create a healthier scalp environment that supports follicle growth and preserves the hair you already have.

What Many Commercial Shampoos Get Wrong

Flip over a typical drugstore bottle, and you’ll often see the following harmful ingredients:

• Sulfates: Harsh detergents that strip natural oils.
• Synthetic fragrances: Common causes of irritation and scalp issues.
• Parabens and preservatives: Used to extend shelf life.

Sulfates create that satisfying lather. They also remove sebum, which protects the scalp. Over time, that dryness can trigger rebound oil production, itchiness or flaking — all of which interfere with consistent renewal cycles.

If you’re chasing thickness, your scalp needs balance, not stripping. That’s where homemade shampoo for hair growth and thickness stands out. You control the ingredients. By avoiding unnecessary fillers, you build something gentle enough for frequent use.

The Power Players in Your Pantry

A strong recipe for hair growth combines cleansing power with circulation-boosting botanicals. Here’s what works and why.

Dried Rosemary or Essential Oil

Rosemary oil has shown comparable results to 2% minoxidil in a recent study. It increases circulation around follicles and may improve shaft thickness over time.

Peppermint and Pumpkin Seed Oil

The same study mentioned earlier noted that 3% peppermint essential oil applied to the scalp has the same benefit as 3% minoxidil, increasing hair density and depth. Men benefit from pumpkin seed oil, which may increase follicle count by 40%.

Vegetable Glycerine

Glycerine is a humectant that preserves moisture, which is why it is often added to cosmetic products like soaps and washes. While it doesn’t force water into dry hair, it can help prevent hair drying out, which makes the shafts stronger and more lush in appearance.

Rice Water

While natural remedies often call for liquid castile soap, this isn’t advisable for use on your hair or scalp, especially with America’s hard water. Instead, a traditional remedy that’s increasingly popular, though not yet scientifically proven, is rice water. It contains amino acids, B vitamins and inositol, which is touted as a hair growth stimulator.

Soaking a cup of raw rice in water for 30 minutes produces a nutrient-rich extract that can be used as a rinse or added to homemade shampoo, as long as you use it quickly. It’s said to promote hair length, though genetics also factor in here.

How to Make Shampoo at Home With Natural Ingredients

This simple, safe formula is ideal if you mix fresh batches each time to prevent spoilage or bacterial contamination. Unlike commercial shampoos, you can easily double wash and enjoy the full nourishing benefits. If you have a family, a washday can be a fun ritual where you mix enough for everyone.

Because this version doesn’t contain surfactants, think of it as a strengthening cleansing rinse rather than a heavy-lather shampoo.

Homemade Shampoo Ingredients

• ½ cup uncooked rice
• 2 cups distilled water
• 2 tablespoons dried rosemary
• 1 tablespoon dried nettle or chamomile
• 1 teaspoon vegetable glycerin
• 1 teaspoon pumpkin seed oil
• 8-10 drops rosemary essential oil
• 3-5 drops peppermint essential oil

Step 1: Prepare the Rice Water

1. Rinse the rice thoroughly with filtered water to remove impurities.

2. Combine rice and 2 cups of distilled water in a clean jar.

3. Let it soak at room temperature for 30 minutes before straining the water into a separate container. Discard the rice. Fermenting rice in water for 24 hours may increase antioxidant levels, but there is also a risk of bacterial contamination, which can trigger scalp issues.

Step 2: Create the Herbal Infusion

In a glass bowl, combine the essential oils and dried rosemary. The grainy flakes act as a gentle exfoliating scrub for the scalp. If you want, you can add a few flakes of sea salt to boost the mix’s volumizing power, but be cautious, as repeated salt exposure can leave your hair brittle.

Step 3: Combine and Finish

Mix one cup of the fermented rice water with the oil infusion. Stir in glycerine and gently shake. It’s a runny mix, and if you’re worried about application, you can use a sponge to apply it to your scalp or gently dispense it from a pump-action bottle onto your head while washing.

Because rice water is reactive, it’s best to use this mix fresh, but it can keep in the fridge for a day. Shake vigorously before using.

Best Results for Growth and Thickness

Always shake the mix before each application. Sponge or drip it directly onto your scalp and gently massage for 1-2 minutes to stimulate circulation. Leave on for five minutes and rinse well.

If your hair feels a little dry, you can apply a small amount of coconut oil to the tips with your fingers before rinsing again. On days when you have exercised, you can remove heavy buildup with a clarifying or sulfate-free baby shampoo to remove excess oil or dirt.

Final Tip for Maximum Volume

Flip your head forward while massaging. This increases blood flow temporarily and amplifies circulation. Pair this habit with consistent nutrition, ensuring you follow a diet rich in iron, vitamin D and omega-3 to support healthy follicle development.

Remember that visible thickness typically takes 3-6 months of steady care. Growth is biological, not instant. You’re building stronger strands at the root — patiently, boldly and naturally.

Reset Your Hair Today

Hair health reflects your biology, habits and environment. It also speaks of how gently you treat your scalp. 

A homemade shampoo for hair growth and thickness won’t transform your hair overnight, but it will reduce irritation and support circulation to create the balanced foundation that follicles thrive in. You deserve strands that feel strong in your hands and confidence that doesn’t fade with a bad hair day.
