Why do many places that recruit hair stylists only rely on sassoon certificates? Can't our infinite thinking surpass Vader and Sassoon? what do you think?

Just like many big companies only recognize Peking University and Tsinghua.

Let me explain something to you.

Because the average level of having sassoon certificate is relatively high, the risk of being recruited by the recruiter will be reduced to a very low level.

Although there are many other experts, after all, there are many people who are very watery. Is that what you mean?

I hope my answer will satisfy you.
