Answer: 15% to 20%
Step-by-step explanation: According to some unofficial rules, the tip should be 20% of the price of the service everywhere. Some consider that the salon stylist offers something more than other types of services, because the salon stylist knows our hair, realizes with us a more intimate relationship, than for example, a waiter, because salon stylist keeps our hair, knows our damaged parts of hair, know how to correct it and so on. Again, according to unofficial rules, more than 20% should be given if we are late for the scheduled term, etc.
