Hair dye

Q: I would like ask when getting ones hair professionally dyed, bleach (ammonia) is normally used to aid in transitioning from dark to light or vice verse. I have heard that ammonia forms a layer over the hair but am unsure whether this is true as Islamicaly permanent dyes are permissible. Please let me know whether getting ones hair dyed professionally is allowed particularly when it's to cover grey hair as a means of adornment for the husband.
