No, indigo cannot reverse grey hair by restoring its natural melanin. Instead, it works as a natural dye to effectively color grey hair, typically by coating the hair shaft with a blue-black pigment.
How Indigo Works to Cover Grey Hair
Unlike chemical dyes that might alter your hair's internal structure, indigo works by depositing color on the outer layer of the hair. It doesn't interfere with the hair's natural melanin production, meaning it won't restore your hair's original color from within. Instead, it provides a color change from the outside.
For effective grey coverage, indigo is rarely used alone. Its best results are achieved when combined with pure henna. This method is considered damage-free and is a popular choice for those seeking a natural alternative to traditional hair dyes. Many individuals, especially those with curly hair, prefer this method due to its gentle nature.
The Henna-Indigo Application Process
To achieve shades ranging from brown to black on grey hair, a two-step process or a pre-mixed application involving both henna and indigo is commonly used.
- Two-Step Process (for dark shades):
- Henna Application: Pure henna is applied first to the hair. This step stains the grey hairs a vibrant orange or red. It's crucial for the indigo to bind effectively in the next step.
- Indigo Application: After rinsing the henna, indigo paste is applied to the now orange-red hair. The indigo then combines with the henna color to create shades of brown (shorter application time) or black (longer application time).
- One-Step Process (for brown shades):
- Henna and indigo powders can be mixed together in specific ratios and applied simultaneously. This method typically yields various shades of brown, depending on the ratio and application time.
