There is a tradition of the Holy Prophet, 'With the help of hair-dye turn old age into youth so that you do not resemble the Jews.' When Imam Ali was asked to comment on this tradition, he said that in the early stage of Islam there were very few Muslims. The Holy Prophet advised them to look young and energetic and not to adopt the fashion of the Jews (priest) having long, white flowing beards. But the Muslims were not in minority then, theirs was a strong and powerful State, they could take up any style they liked.
