Ruling on a woman applying kohl to her eyebrows for adornment

What is the ruling in the Shari'ah regarding a woman applying kohl to her eyebrows for adornment?
Answer: I do not know of anything specific regarding this. However, if she has gray hair, she is not permitted to change the gray hair with black dye; because the Messenger of Allah (peace and blessings be upon him) prohibited changing [the hair] to black. He said: . So, if she dyes her gray hair with something other than black, such as henna or the like, there is nothing wrong with it. As for changing the gray hair in the eyebrows or on the head to black, it is the same as for a man. Yes.
