The insurance a salon actually needs starts with general liability and professional liability, because the two most likely claims are a slip on your floor and a service that goes wrong on a client. Those two cover the everyday risks that can otherwise end a small salon overnight.
Layer what fits your setup
Property coverage for your space and equipment. Workers compensation if you have employees, which most states require. And make sure booth renters carry their own policies, in writing, so their risk is not quietly yours.
Use an agent who insures salons
A generic small-business policy can miss the service-related claims that are most common in this trade. Talk to an agent who insures salons specifically, and ask them to walk you through the claims they actually see, not just the products they sell.
Why it matters
This is not the exciting part of owning a salon. It is the part that lets you keep owning one when a bad day arrives, instead of losing everything you built to a single claim.
