This is the most common thing among girls and women. They use to beautify themselves by plucking eyebrows, removing facial hairs, etc. But they don't know that it is haraam. 'Yes, It is Haraam!'
Narrated `Abdullah:
Allah has cursed those women who practice tattooing and those who get themselves tattooed, those who remove their face hairs, and those who create a space between their teeth artificially to look beautiful, and such women as changing the features created by Allah. Why then should I not curse those whom the Prophet (ﷺ) has cursed? And that is in Allah's Book. i.e. His Saying: 'And what the Apostle gives you take it and what he forbids you to abstain (from it).' (59.7)
