Abu 'Umayr bin Anas bin Malik أبو عمير بن أنس بن مالك الأنصاري · The Chapters on Marriage

"A woman came to the Prophet and said:, My daughter is going to get married, and she had the measles and her hair has fallen out. Can I put extensions in her hair?, The Messenger of Allah said: ‘Allah has cursed the one who does hair extensions and the one who has that done.'"
