Is it permissible to trim eyebrow hair temporarily instead of bleaching until the burned skin heals?

It is permissible to trim the eyebrows out of medical necessity, or if the hair is excessively long to a harmful or disfiguring extent, provided that one limits oneself to removing only this disfigurement. However, if there is no medical necessity or disfigurement, it is not permissible to trim them, and this remains subject to the original absolute prohibition, regardless of the husband's permission or whether the woman wears a niqab.
