If they don't engage you in small talk they don't care if you talk to them or not. Make sure you have showered/bathed before you leave the house and hair cuts are simple. Tell them what you want, sit down and have it done. Thank them, pay and leave.>>236564
Hair makes a big difference in how people react to you and how you look. A good hair cut can put a slightly below average guy to slightly above average by framing his face better. Your outer appearance influences how people around you respond to you. A haircut every few months and wearing some clean clothing will make it easier to ghost instead of being the homeless guy everyone stares at. You don't need to dress expensive, as long as you're not morbidly obese you can get fitting clothing cheap off of ebay and be fine. A $15 outfit (excluding shoes) is enough to blend in as a normalfag and be left alone.
