How much gratuity is correct for a hair salon?

A typical gratuity for a hair salon ranges from 15% to 20% of the total service cost. For exceptional service, you might consider tipping more, while for unsatisfactory experiences, a lower percentage may be appropriate. It's also common to tip each stylist or technician individually if multiple people work on your hair. Ultimately, the amount you choose to tip should reflect your satisfaction with the service.
