"I heard 'Aishah say: 'The Messenger of Allah forbade the woman who does tattoos and the woman who has that done, the woman who affixes hair extensions and the woman who has that done, An-Namisah (the one who does the plucking) and Al-Mutanammisah (the one who has it done).'"
Sunan an-Nasa'i Book 48, Hadith 62
