Hello. can masturbating a lot while on propecia (finasteride) cause the propecia (finasteride) not to work and cause a lot of hair loss? thanks

Unrelated: Masturbation does not cause hair loss, or any other ill-effect. It does not interfere with Propecia (finasteride). For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex.
