^ I wonder why Uchiha Barles is trying so hard to help you, Sapphire.

Just convince him to wash his hair through the following steps:

  1. Ask him nicely.
  2. Use scientific facts to back up your argument.
  3. Nag him some more if you have to do so.
  4. Febreeze his hair.
  5. If none of the above works, kick him out (be polite about it).
