Is Nutrisse 3 Morkebrun safe for sensitive scalps or chemically treated hair?

The dye contains ammonia, fragrance and potent colorants such as resorcinol and p-phenylenediamine sulfate, which can irritate sensitive scalps or previously treated hair; a patch test 48 hours before use is strongly recommended.

What role does ammonium hydroxide play in this hair dye formula?

Ammonium hydroxide raises the pH of the mixture, opening the hair cuticle so that the pigment molecules can penetrate the cortex and develop permanent color, but it also contributes to the product's characteristic odor and can be harsh on the skin.

How often can this dye be reapplied and are there any controversial ingredients to be aware of?

Most professionals advise waiting 4-6 weeks between applications to avoid over-processing; the formula includes controversial substances such as resorcinol, p-phenylenediamine sulfate, toluene-2,5-diamine, BHT and synthetic fragrance, which may cause allergic reactions or irritation in some users.
