What is the ruling on women permanently removing hair such that it will not grow again, by means of cosmetic such as creams and herbs? Is that regarded as changing the creation of Allah ﷻ?

Shaykh ʿAbd al-Azīz bin ʿAbdullah bin Bāz:

There is no problem or sin in doing so It is not considered a form of changing [the creation of Allah ﷺ] that is forbidden. There is nothing wrong in permanently removing hair from the armpit or pubic region, rather it is sunnah to do so. The Prophet commanded that people shouldn’t pass forty days without removing the pubic and armpit hairs, trimming the nails and mustache. So if a man or woman removes hair from the armpit or pubic region using a permanent method that will prevent it growing back, there is nothing wrong with that and there is no sin in doing so.
