Why Herbal Hair Colour Sometimes Fails on Grey Hair
Many people today prefer natural hair colouring methods because they want to avoid harsh chemicals found in traditional dyes. One of the most popular choices is herbal hair colour since it is made from plant based ingredients such as henna indigo and other botanical powders.
However many users notice that grey hair does not always absorb herbal pigments the same way as normal hair. When hair turns grey it loses melanin and the texture of the hair strand changes. This often makes grey hair more resistant to colour absorption.
Another important factor is how natural colouring works. Herbal colours coat the outer surface of the hair instead of penetrating deeply like chemical dyes. Because of this the preparation method mixing time and application technique can strongly influence the final colour result.
