What type of hair care service is a barber NOT typically authorized to perform?

Barbers are primarily trained to perform grooming services related to hair, such as cutting, styling, and some chemical treatments which include hair coloring and certain scalp treatments. However, the practice of performing cosmetic facial applications generally falls outside the scope of a barber's traditional training and licensure. This type of service typically requires a different skill set and often necessitates a license in esthetics or cosmetology, as it involves working with facial skin and applying various cosmetic products to enhance beauty or address skin concerns. Since this is not typically included in barber training, performing these services would not be authorized under standard barbering practices.
