Welcome to HCM.
is not harmful to the body and you do not have to feel guilty about it. After masturbation you have to see that you clean your private parts and surrounding area and keep it dry. Masturbation is not related to hair fall
If you still want to stop daily masturbation, avoid seeing sexually stimulating pictures, magazines, movies etc. and concentrate on your study / work, socialise and mix with friends, avoid situations in which you are alone.
