🌱 What Makes This Shampoo So Special?

This DIY shampoo is designed for people seeking a natural remedy for hair loss, slow growth, dull strands, or scalp irritation. Instead of harsh detergents, it uses:

• Avocado shell, rich in fatty acids and antioxidants, to stimulate follicles
• Ground coffee, which boosts circulation and may slow graying
• Cinnamon, with its anti-inflammatory and antifungal properties
• Rosemary, known to reduce hair shedding and increase thickness
• Cloves, which cleanse and strengthen the scalp

These ingredients are simmered into a herbal infusion and then added to a base of neutral, unscented shampoo (without parabens or sodium chloride). The result is a chemical-free cleanser that nourishes from root to tip.

🍶 Ingredients You’ll Need

• 1 tablespoon dried and grated avocado shell
• 1 tablespoon ground coffee
• 1 teaspoon cinnamon powder
• 5 sprigs fresh rosemary or 1 tablespoon dried
• 5 to 7 whole cloves
• 1 cup filtered water
• 1 cup neutral shampoo (free from sulfates, salt, or parabens)

Optional: a few drops of rosemary essential oil or peppermint for scent and added stimulation.

🧴 Step-by-Step Instructions

Step 1: Create the Herbal Infusion
In a saucepan, bring 1 cup of filtered water to a light boil. Add rosemary, cloves, and the grated avocado shell. Lower the heat and simmer gently for 10 minutes.

Step 2: Add Coffee and Cinnamon
Turn off the heat and stir in the ground coffee and cinnamon. Cover the pan and let everything steep for 30 minutes as the infusion cools and darkens.

Step 3: Strain and Combine
Once cooled, strain the mixture through a fine mesh strainer or cheesecloth. Pour the herbal infusion into a clean container and mix with 1 cup of neutral shampoo. Stir or shake gently to combine.

Step 4: Store the Shampoo
Transfer the shampoo to a clean bottle with a lid. Store in a cool, dark place for up to 15 days.

Step 5: How to Use
Apply to wet scalp. Massage gently for 3 to 5 minutes, focusing on the roots. Let sit for another 5 to 10 minutes. Rinse thoroughly with lukewarm water. Use 2 to 3 times per week for best results.

⚠️ Common Mistakes to Avoid

Using boiling water directly on herbs
Boiling destroys delicate nutrients. Instead, simmer gently and steep.

Skipping the straining step
Whole grounds or shells left in your shampoo can clog your hair or pipes. Always strain well.

Applying to dry scalp
Wet hair and scalp help the shampoo spread more evenly and absorb better.

Using every day
This shampoo is potent—overuse may dry your scalp. Stick to 2–3 times weekly.

Forgetting a patch test
Some natural ingredients may irritate sensitive skin. Always test a small amount first.

🌟 Benefits of Each Ingredient

Avocado Shell
This often-discarded part of the fruit is rich in phenols and natural oils. It gently exfoliates the scalp, nourishes hair follicles, and adds a natural shine.

Ground Coffee
Caffeine helps stimulate blood flow to the scalp and can block DHT, a hormone linked to hair thinning. It also naturally darkens hair and improves luster.

Cinnamon Powder
Packed with anti-fungal and anti-inflammatory properties, cinnamon helps keep the scalp clean while encouraging healthy follicle activity.

Rosemary
One of the most powerful herbal allies for hair growth. It increases cellular metabolism and has been shown in studies to be as effective as minoxidil for regrowth.

Cloves
These aromatic buds contain eugenol, which improves blood flow and can strengthen hair roots. They also reduce dandruff and itchiness.

🌍 Seasonal & Regional Adjustments

In Hot or Tropical Climates
Reduce cinnamon (it can overheat the scalp) and refrigerate shampoo between uses.

In Cold or Dry Climates
Add a teaspoon of olive or jojoba oil to the final mix for extra moisture.

In Humid Areas
Use apple cider vinegar rinse afterward to balance scalp pH and prevent fungal buildup.

If You Don’t Have Rosemary or Cloves
Try sage or thyme as substitutes—they offer similar antimicrobial benefits.
