“Most people will do $5.” Others said people should leave a similar tip to what they would leave at a restaurant. “I would say around 20% is fine,” said Adam Quintero, owner of Up Hair in the Castro. Stong Guo, the owner of Russian Hill's Tulip Salon, gave similar advice for what amounts to a good tip.

Do tip 15-20% of the total cost. The standard tip for a barber or hairdresser is 20-30% of the total cost of the service. This is a good baseline to use, but you can adjust the tip based on your satisfaction with the service and your personal budget. Don't feel obligated to tip more than you can afford.

While the general tipping standard for haircuts is 15-20%, tipping for other services, such as shaves or beard trims, varies. Some barbers may expect a higher tip for these services, while others may not. As a general rule of thumb, it's a good idea to tip between 20-25% for “special” services: Shaving.

Salons often use high-quality, professional-grade products that are more expensive than the ones you might find in a supermarket. These products are designed to be gentle on the hair, offer better results, and are often ethically sourced and produced. The use of such products is factored into the haircut prices.
