Have you spotted a few silver strands and wondered if there’s a gentle, natural way to restore your hair’s color—without harsh chemicals or dyes? A DIY “black shampoo” made with ingredients like banana peel and other natural botanicals has been gaining attention for its surprising results.
Some claim it softens the appearance of gray hair after just one use. While it’s important to manage expectations, this kind of natural remedy may help nourish the scalp and temporarily darken hair with consistent use.
Let’s explore what’s behind the trend and how you can try a gentle version at home.
What Is “Black Shampoo”?
“Black shampoo” isn’t an actual commercial product but rather a name for homemade rinses or treatments made from natural darkening ingredients—like banana peels, black tea, coffee, or herbs.
One popular version involves soaking banana peels in a mixture of natural oils or water to create a nutrient-rich blend that is massaged into the hair and rinsed out after a few minutes.
Common ingredients include:
- Banana peels (rich in antioxidants and minerals)
- Coconut oil or olive oil (for moisture and shine)
- Black tea or coffee (natural coloring properties)
- Fenugreek, amla, or rosemary (traditionally used in natural hair care)
How to Make DIY Black Shampoo
This version is simple, gentle, and easy to try:
You’ll need:
- 2 banana peels (fresh or slightly overripe)
- 1 cup hot water or strong brewed black tea
- 1 tablespoon coconut or olive oil
- Optional: 1 teaspoon black coffee grounds
Instructions:
- Cut the banana peels into strips and place them in a jar.
- Pour the hot water or tea over them.
- Let steep for at least 12–24 hours.
- Strain the liquid and add your oil.
- Shake well before use.
To use:
- Massage into damp hair and scalp.
- Leave on for 2–5 minutes.
- Rinse thoroughly.
- Repeat 1–2 times weekly.
This method does not dye the hair permanently, but may help enhance dark tones, reduce dullness, and soften gray strands temporarily.
What Results Can You Expect?
After the first use, your hair may feel:
- Softer and more hydrated
- Smoother with a natural sheen
- Slightly darker in appearance, especially if used after black tea or coffee-based shampoos
Some users report that regular weekly use can create a subtle darkening effect over time, especially on early-stage gray hairs. However, results vary depending on your natural hair color, porosity, and hair condition.
Is It Safe?
According to sources like WebMD and Mayo Clinic, banana peels and herbal rinses are generally safe for topical use. But always:
- Do a patch test first to rule out sensitivity
- Avoid contact with eyes
- Use caution if allergic to bananas or caffeine
- Natural treatments can be a great option for people who want to avoid commercial dyes, but they won’t replace professional coloring if full gray coverage is your goal.
Final Thoughts
Natural “black shampoo” is not a magic fix, but it can be a soothing, plant-based way to nourish your hair and help tone down early grays. For many, it’s part of a self-care routine that’s gentle, low-risk, and budget-friendly.
