Tum'a: Scratching your Head

You must wash your hands (the One-Time Method) if you scratch your head on a place where you have hair. You do not need to wash your hands if you:
  • Touch your hair
  • Scratch a bald spot.
  • Rub your head instead of scratching it.
Reason Scratching your head (where there is hair) causes tum'a because of any impurities that may be there.
Note Even if you have just shampooed your hair, you must still wash your hands.
