A Few Things to Keep in Mind Before You Start
- Always do a patch/strand test first. Even though herbal henna powder and indigo are natural, everyone’s skin and scalp react differently. Testing before full application ensures you avoid any unexpected irritation.
- Every hair type is unique. What works for one person may not be the perfect recipe for another. Some may find henna slightly drying, so it’s a good idea to mix in hydrating ingredients like aloe vera powder or nourishing oils.
- Moisture is key. For the best results, follow up with a deep conditioning treatment 5–7 days after colouring once the colour has fully settled.
- Customize your recipe. Adjust your henna–indigo mix depending on your hair’s needs, whether that’s extra conditioning, stronger colour, or scalp care. The right recipe is the one that suits your hair best.
What Are Herbal Henna & Indigo?
- Herbal Henna (Lawsonia inermis): A natural dye that gives hair an orange-red tint. It also acts as a conditioner, adds shine, and promotes scalp health.
- Indigo (Indigofera tinctoria): A blue-black dye that, when applied over henna, creates natural brown to deep black shades.
Together, they form a completely natural hair dye system that is safe, long-lasting, and effective for covering greys.
Shades You Can Achieve with Henna + Indigo
- Soft Brown - Equal parts Henna + Indigo (1:1)
- Dark Brown - 30% Henna + 70% Indigo
- Jet Black - 20% Henna + 80 - 100% Indigo
- Reddish Brown - Henna + Hibiscus + Indigo

(Pro Tip: The higher the ratio of indigo, the darker your hair will turn out.)
