In the economy, a service refers to a benefit consumers obtain due to the skills, experience or abilities of the seller. A service differs from a product because the customer does not obtain a good. Examples of services include education, car-repair services or haircuts. Additionally, most services are purchased as you pay for them; although some such as education are covered by the government.
According to this, it is true, getting a haircut from a barber is an example of a service that can be purchased because the customer obtains a benefit (the haircut) rather than a good and needs to pay for it as this involves the skills and knowledge of the barber.
