Will this product change the color of my hair, especially if it is dyed?

Fitocosmetic Colourless Henna Extra is made from Cassia italica leaf powder, which is distinct from the Lawsonia inermis plant used for traditional red henna. Because Cassia does not contain the orange-red pigment (lawsone) that binds to keratin, it will not deposit a copper hue or alter your natural hair color. This makes it a safe choice for both natural shades and previously dyed hair, provided you are looking for cosmetic benefits rather than color change.

Instead of tinting, the fine powder forms a light, transparent film over the hair shaft. This coating smooths the cuticle, which can enhance the reflection of light, giving your existing color more shine and depth. If you have recently colored your hair, this treatment can help maintain a polished, glossy look without risking unwanted tonal shifts or brassiness that some herbal treatments might cause.
