Is this plant-based hair dye safe for sensitive or dry scalps?

It is free from harsh chemicals such as ammonia, PPD and peroxides, making it gentler for sensitive or dry scalps, but because it contains natural pigments, a patch test is still recommended to detect any possible irritation.

What does indigo (Indigofera tinctoria) contribute to the color and care of hair in this formula?

Indigo supplies the deep brown-to-black pigment that, when combined with henna's red tones, creates the rich chestnut shade, and it also helps condition the hair by smoothing the cuticle.

How often should this chestnut henna dye be applied and does it contain any controversial ingredients?

The dye can be reapplied every four to six weeks, and its formulation intentionally omits ammonia, synthetic dyes, PPD, picramic acid, peroxides and metallic salts, so it contains none of the commonly disputed hair-dye chemicals, though natural ingredients may still cause allergic reactions in some users.
