Here’s a detailed, natural recipe to change gray hair to black using coffee and indigo powder. This method uses plant-based ingredients, and although results vary depending on your hair type and how often it’s applied, it’s a popular natural approach.
🌿 Natural Hair Coloring with Coffee & Indigo Powder
🧴 Ingredients:
Step 1: Coffee Hair Dye Base
-
2 tablespoons organic instant coffee or fresh ground coffee
-
1 cup water
-
1 tablespoon coconut oil (optional – adds moisture and shine)
-
1 teaspoon apple cider vinegar (optional – helps with pH balance and color hold)
Step 2: Indigo Dye Mix
-
100g indigo powder (adjust based on hair length)
-
Warm water – enough to make a paste (not hot!)
-
1/2 teaspoon salt (optional – helps bind color better)
-
1 teaspoon corn starch or yogurt (optional – to improve consistency)
🔧 Tools Needed:
-
Glass or plastic mixing bowl (avoid metal)
-
Spoon or whisk (non-metal)
-
Gloves
-
Shower cap or wrap
-
Old towel (to protect clothes)
-
Applicator brush (optional)
✨ Step-by-Step Instructions:
🔹 Step 1: Coffee Rinse / Base Prep
-
Boil 1 cup of water.
-
Add 2 tablespoons of coffee. Let it simmer for 5–10 minutes.
-
Cool the mixture to lukewarm.
-
Optionally, add 1 tbsp coconut oil and 1 tsp apple cider vinegar.
-
Use this strong coffee as a hair rinse or mix it with your indigo paste later.
🔹 Step 2: Indigo Paste Preparation
-
In a non-metal bowl, mix indigo powder with lukewarm coffee (or plain warm water) to form a thick paste.
-
Add salt to enhance color binding if desired.
-
Let the paste sit for 15–30 minutes to activate (unlike henna, indigo needs minimal oxidizing time).
-
Use immediately for best color results.
🔹 Step 3: Application
-
Wash hair with a mild, sulfate-free shampoo (no conditioner).
-
Towel-dry until just damp.
-
Section your hair.
-
Wearing gloves, apply the indigo-coffee paste evenly from roots to tips.
-
Wrap your hair in a shower cap or cling film to retain moisture.
-
Leave it on for 1–2 hours (longer = deeper color).
🔹 Step 4: Rinsing
-
Rinse hair with cool to lukewarm water only — do not use shampoo for 24–48 hours.
-
After that period, wash with a mild shampoo and condition normally.
🕓 Frequency:
-
Use weekly or bi-weekly for best results.
-
After 2–3 applications, gray hair should turn to a natural dark brown to black tone.
-
Color deepens with each use.
💡 Tips:
-
Do a strand test before full application.
-
Avoid mixing indigo with lemon or acidic ingredients (it prefers a neutral or slightly alkaline pH).
-
For even deeper black, do a two-step process: first apply henna (reddish base), rinse, then indigo.
