Dyeing the hair
Another aspect of beautification relates to dyeing the gray hair of the head or the beard. It was reported that the Jews and Christians refrained from dying the hair, regarding such beautification and adornment as contrary to piety and devotion, and not befitting rabbis, priests, and ascetics. The Prophet (saw) forbade Muslims to imitate these people or follow their ways, in order that Muslims might develop their own distinctive and independent characteristics in appearance and behaviour.
Prohibition of tattooing, cutting the teeth, and undergoing surgery for beautification
Among such excesses are tattooing and shortening the teeth. The Messenger of Allah (saw) cursed the tattooer and the one who is tattooed, the shortener of teeth and the one whose teeth are shortened (Muslim).
Why gold and silk are permitted to women
Woman has been exempted from this prohibition out of consideration for her feminine nature, as the love jewelry and ornaments is quite natural and becoming for a woman. However, she is not to use her adornments to attract men and arouse their sexual desires.
