What is the ruling on removing excess hair from parts of the body that causes stains on clothes and prevents the proper performance of ghusl after defecating?

It is permissible to remove pubic hair by any possible means. Pubic hair refers to the hair that grows around the private parts (front and back) for both men and women. Care must be taken to completely remove any impurities (najasah) after hair removal. No leniency is granted for impurities if they spread beyond their usual place.
