Using black dye for the hair
Machine translationRead the Arabic original
Question:
The questioner asks: Is it permissible to use "dough," which is a type of henna but gives the hair the color of henna? And is it permissible to use it as a kit for henna?
Answer:
If the dye is black and changes the gray hair to make it black, there is nothing wrong with it. However, if the dye is pure black, it should not be used on gray hair. The Prophet (peace and blessings be upon him) said:Mishkat al-Masabih 4424. So, if the dye does not turn the gray hair black, but is between red and black, or is red, there is nothing wrong with it. As for the hands, using henna on the hands is fine, and even if it is black on the hands, there is nothing wrong with it. Yes.
