Is it permissible to pluck eyebrows lightly and subtly, given the hadith, "May Allah curse the one who plucks eyebrows and the one for whom they are plucked?"

It is not permissible for a woman to remove anything from her eyebrows for beautification, and the authentic hadiths indicate this. The female journalists you mentioned are not role models; rather, the role models are those committed to the Sharia, such as the Mothers of the Believers, the venerable female Companions, and the women of the righteous predecessors. Adherence to the hijab is a strong manifestation of commitment, but it is only one part of Allah's commands for women. Therefore, she must complete it with the rest of the religious commands, such as refraining from nams (plucking eyebrows), tattooing, hair extensions, and other similar practices.
