Because each school teaches different technologies and targets different people.

Some are aimed at zero-based Xiao Bai, some are aimed at assistant hair stylists, and some hair stylists with more than ten years want to make further breakthroughs.

This is like how to rank without level. If you insist on ranking,

It must be a ten-year hair stylist course, but have you considered a zero-based apprentice?

Can they understand such profound knowledge, can they understand it,

On the contrary, some easy-to-understand primary courses are more suitable for this group of people.

In fact, I'm quite optimistic about a school, Tony Gai, Beijing, which offers three levels of courses.

For the zero-based white course, three months, cutting, dyeing and ironing.

Assistant hairstylist course, one month, technical tailoring.

More than ten years of master's courses, one month, advanced tailoring.

Each course takes into account what courses students at different levels need to study, which is very detailed.
