Do you need to cover grey hair or completely change your color? Then the permanent ammonia-free hair dye Schwarzkopf Professional IGORA ZERO AMM is made for you! The dye creates an intense but natural-looking color that lasts a long time. Its formula enriched with grape seed oil and apricot kernel oil promotes the hair's moisture balance and, being ammonia-free, does not give off the typical unpleasant smell.
