Two people get the same helix piercing. One heals in seven months with zero drama; the other fights irritation bumps for a year and eventually retires the piercing. Very often the difference wasn't aftercare — it was decided the moment the needle went in: angle, jewelry quality, sterile technique.
A great piercer is part anatomist, part jeweler, part clinician. They'll refuse placements your anatomy can't support, insist on metal your skin won't react to, and put the hole at an angle that heals instead of fights. That skill is worth researching for, and worth traveling for.
The good news: bad studios are easy to spot once you know the tells. You can vet a shop in fifteen minutes of research plus one walk-in visit.
