Let's do this again!

Who wants to hang out with their best friend when they have bad hair?

Me.

I think that is the evidence he is no longer your best friend. He has moved on as tends to happen in life, so it may be best if you do to.

I'd say that is the evolution of the "I have to wash my hair" excuse. Move on!

We haven’t seen your friend so maybe he did need a haircut. If he’s a guy that should only take like 30min. If your friend is a women then it could take longer depending on what she’s getting done. Either way your friend should have called/texted and said he/she is running late or not able to come at all.

he's not a friend, friend, drop him even if that means you have no friends

Why would you wait 3 hours before texting him?? You need to value your own time more

geez buddy. Take the hint!

Read "How to make friends and influence people" by Dale Carnegie. That will give you the people skills to make new, real friends. Also join a new activity like larping or dancing or volunteering for conservation or something. This will help you meet new people. And dump your friend.

You live in Portland. What kind of friends were you expecting?

Sounds like maybe he isn't your best friend anymore. When my former BFF began ditching me for a bad crowd or made up stupid excuses, that was a sign for me to move on with my life. Perhaps it's time for you to do the same.
