Abu Dawud (may Allah have mercy on him) said: 'al-wasilah' is "the woman who joins other hair to women's hair"; 'al-mustawsilah' is "the one who has hair attached"; 'al-namisah' is "the one who thins the eyebrows"; and 'al-mutanammisah' is "the one who has her eyebrow hair thinned". 'Al-washimah' is "a woman who fills moles on her face with kohl or ink", and 'al-mustawshimah' is "the one who has moles filled in".
Al-Farra' (may Allah have mercy on him) said: 'al-namisah' is "the one who plucks hair from the face", and 'al-minmas' (tweezers) is "that with which she plucks the hair".
