In an extreme case of untrimmed eyebrows like the one below. Is it still unacceptable to adjust or groom it by plucking or shaving?
Like wise in other exteme cases of physical abnormalities, is it permitted in islam to bypass the prohibition of cosmetics to bring back the abnormal to normal (even if the abnormal causes no medical harm to the human, only in appearance)?
