Hair and Nails

Disposing hair

Q: If a person shaves his moustache over the bathroom sink every morning, would this be OK even though the stubbles of hair will go down the drain? Or does he have to shave over a container to collect the stubbles of hair in order to bury them?

Laser hair removal around private area due to medical reasons

Q: If a man develops repeated abscesses on his private parts and the surgeons advise laser to remove the hairs around the private area permanently as the hairs contribute to abscess formation, would it be permisible to expose the private parts to male or to female nurses/doctors for laser? Since shaving with a razor is thought to increase the abscess formation.
