What is the ruling on dyeing a woman's hair black if it is not to change the gray hair?

Question : Shaykh, the questioner asks: What is the ruling on a woman using black dye on her hair, which makes the hair black?

Answer : If the black dye is used to hide the gray hair, then that is forbidden. This is in accordance with the saying of the Prophet (peace and blessings be upon him): "Change this gray hair and avoid black." There is also a hadith reported on this matter containing a warning. As for if it is for other than that, it appears to be permissible. That is, if a woman's hair tends toward yellow, and she dyes it black to remove that yellowness, it appears that there is nothing wrong with that. Yes.
