How many shampoos should a student complete in a 250-hour barber course?

In a 250-hour barber course, the requirement for student training often includes practical skills that are essential for a barber's foundational techniques. One key component is the number of shampoos a student must complete to gain experience and competence in performing this fundamental service.

The requirement of 20 shampoos in this context is designed to ensure that students have ample opportunity to practice and perfect their technique. This includes understanding the different hair types, proper shampooing methods, and providing a pleasant experience for clients. Meeting this requirement helps in building confidence and skill before students transition to providing services in a professional setting.

While the other options suggest numbers that seem less aligned with the scope of the training hours, they do not match the standard expectations set by the curriculum or regulatory bodies overseeing barber education, which firmly establish 20 as a practical and achievable number for proficiency during the course.
