The Prophet (ﷺ) has cursed the lady who lengthens her hair artificially and the one who gets her hair lengthened, and also the lady who tattoos (herself or others) and the one who gets herself tattooed.
Sahih al-Bukhari Book 77, Hadith 155
← Previous Hadith `Abdullah cursed those women who practiced tattooing and those who removed hair from their faces and those who created spaces between their teeth artificially to look beautiful, such ladies as changed what Allah has created. Um Ya'qub said, "What is that?" `Abdullah said, "Why should I not curse those who were cursed by Allah's Messenger (ﷺ) and are referred to in Allah's Book?" She said to him "By Allah, I have read the whole Qur'an but I have not found such a thing. `Abdullah said, "By Allah, if you had read it (carefully) you would have found it. (Allah says:) 'And what the Apostle gives you take it and what he forbids you abstain (from it).' (59.7)

Sahih al-Bukhari Book 77, Hadith 154 Next Hadith → A woman asked the Prophet (ﷺ) saying, "0 Allah's Messenger (ﷺ)! My daughter got measles and her hair fell out. Now that I got her married, may I let her use false hair?" He said (to her), "Allah has cursed the lady who lengthens hair artificially and the one who gets her hair lengthened artificially."
