Is it true that Putting Khizab with Henna(Mehdi)is a sunnah and with colour not allowed. Now adays a type of henna called “Black Henna” (Kali Mehdi), containing black dye is widely awailable and people used it to colour their white hairs and say it is sunnah. Is it allowed or not?
Answer:
(Fatwa: 255/231=D/1430)
Henna is the same as menhdi. Dyeing with henna is proved from hadith. By applying henna the hair gets reddish colour, it is allowed to apply it. If black henna blackens the hair it will be unlawful as it is prohibited in hadith.
