Her hair is black, so is it permissible for her to dye it with other colors?

Question:
May Allah reward you with good, and may He do you good. Our sister is asking about the ruling on dyeing hair, meaning changing its color from black to blonde or red?

Answer:
Dyeing hair and changing its color is only mentioned in the context of changing white hair. The Prophet (peace and blessings be upon him) said, "Change this white hair and dye it black." What the Prophet (peace and blessings be upon him) commanded to be changed is white hair. As for hair that is not white, if it is disfiguring and out of the ordinary, there is no harm in changing it to a suitable color. However, if the hair is not disfiguring and is in its normal state, it is not permissible to change it because of the frivolity and affectation involved, and possibly the imitation of disbelieving women. This is because some Muslim women, when they see images of disbelieving women on television or in some series, try to imitate their hair and hairstyles. This is a type of condemned imitation. Therefore, changing normal hair to another color, when it is not disfiguring and has no issue, is frivolity. It is better to avoid such matters. Yes.
