Hair coloring products contain many ingredients that can irritate the skin and cause allergic reactions. Most cases of allergic contact dermatitis stemming from exposure to hair dye are caused by an ingredient called PPD and Ammonia. Hair dye does not stop or even slow down hair growth, but it can cause hair loss by damaging the colour-treated hair. The chemicals in hair dye can cause some of the damage. But you can experience an increase in hair shedding with frequent colouring sessions. Telogen effluvium is the medical name for a form of hair loss.
