Is it permissible for a woman to completely remove her body hair with the help of a beautician for her husband, and is this act halal, and what does it require of her?

For a woman to undress in front of another woman to remove body hair is not permissible in Islamic law. It is obligatory to advise and condemn anyone who engages in such an act. Guardians must prevent their daughters from such behaviors, for they are responsible and accountable for them, based on Allah’s Almighty saying: "O you who have believed, protect yourselves and your families from a Fire whose fuel is people and stones" (Quran 66:6). And the Prophet, peace and blessings be upon him, said: "There is no servant whom Allah entrusts with a flock and he dies on the day he dies while he was deceitful to his flock, but Allah will forbid Paradise for him."
