Q: I have been wondering whether having bikini waxes are permissible in Islam since modesty and covering our nudity is an important tenet of our religion. My understanding is that for a woman to expose herself to another woman is not permissible, unless it is necessary for valid reasons such as medical treatment.
A: Yes, exposure will only be allowed when necessary; as in medical treatment. This type of waxing can be done by the lady herself.
Allah Ta'aala knows best.
