Men and women are allowed to change the color of their hair with any hair coloring besides black. They may get rid of the gray in their hair with such substances as henna or saffron.
Dyeing the hair black:
Answered by: Sheikh `Abd al-Rahmân F. al-Jar`î, professor at King Khâlid University, Abhâ
In my opinion, the best opinion regarding dyeing the hair or the beard black is that it is merely disliked, since the hadîth which prohibit it are not authentic in their lines of transmission. One of the most important of these hadîth is the one related by Jâbir b. `Abd Allah that Abu Quhâfah arrived after the conquest of Mecca with his beard completely white. Then the Prophet (peace be upon him) said: “Dye it, but avoid using black coloring” [Sahîh Muslim (2101)]. However, the phrase “avoid usling black coloring” is not authentic, as some scholars have cited.
The second hadîth on this matter was related by Ibn `Abbâs that the Prophet (peace be upon him) said: “There will be some people at the end of time who will dye their hair as black as crows and they will not smell the scent of Paradise." [Musnad Ahmad (1/273)] This hadîth is weak, because it is line of transmission is disputed.
Therefore, the best opinion is that dyeing the hair black is disliked, since this takes into account the command of avoiding black found in the hadîth and also the opinions of some prominent Companions like al-Hasan , al-Husayan , `Uthman , Sa`id b. Abi Waqqâs, Jarîr b. `Abd Allah, `Amr b. al-`As and many of the successors, as cited by Ibn Jarîr and Ibn al-Qayyim .
Ibn al-Qayyim writes in Tahdhîb al-Sunnan (6/10): “Dyeing with black was disliked by group of scholars, and this is the correct position on the matter.”
And Allah knows best.
