1992 — Where It Began
Our story began with raw hair material. When China's hair extension industry was still in its early stages, our founder's family began collecting, sorting, and evaluating raw human hair by hand.

Our Story : Since 1992 · A Life in Hair
Mr. Cao has spent his whole life in hair — from a boy in his father's courtyard in 1992 to the man supplying professionals in 100+ countries today.
Mr. Cao when he started in this trade and the honest answer is: before he was old enough to know it was one. In 1992, when he was a boy, there was no hair extension industry in China. No trade shows. No catalogues. No factory with the word hair on the gate. There was only raw material — and his father, Mr. Cao Sr., walking from village to village collecting it by hand while most people thought he was wasting his time. In that house, the work was never in another room. Hair was graded across the courtyard and sorted at the table the family ate at. Other children came home to the smell of dinner cooking. He came home to the smell of clean hair drying in the sun — to the low bargaining of buyers and sellers at the door, and to a hand running down a strand to judge in one second what most people could not judge at all. He started by helping after school, the way children do in a family trade — carrying, sorting, watching. Nobody sat him down to teach him. He simply grew up inside it. And by his teens he had absorbed the things that cannot be written into a specification: what good hair sounds like when you run your fingers through it, what a bad batch looks like before anyone else notices, and how much of this trade is patience.
In 1998 his father built a small factory to hold his own standards. That workshop is the ancestor of Haiyi Hair Mr. Cao grew up alongside it — and then went to work in it, properly, as a young man、 Sorting、Wefting. Quality control. The long arguments over a batch that was almost good enough. He learned the floor before he ever led it, and the material before he ever sold it.So when the business became his, he did not arrive as an heir waiting for a title. He arrived as the one person in the building who had done every job in it.
His father's generation had proven what good raw hair should be. Mr. Cao set out to prove something harder: what it could become in a professional's hands.Because in this trade the truth is uncompromising. Extensions are installed once by a stylist — and then they are simply her hair. She washes them, blow-dries them, colours them, curls them, sleeps in them, walks out into the rain in them. There is no special routine, no gentle handling, no separate life for the hair she was born with and the hair we made. And with Haiyi hair, that goes on for up to a year.A year is a long time for a material to keep a promise.So he rebuilt the business around what survives it. Cuticles aligned in one direction, so it never tangles into a matte. Weight distributed so it never pulls at the root. Strands that hold colour, take heat, and come back from the hundredth wash still looking like hair — not like product. Wefts engineered so the install is faster and cleaner, giving a stylist back the one thing she can never buy more of: her time.
Standards his father would recognise — pushed to a place his father's generation never had the tools to reach.
That is the part no one had done before him.Into salons, behind the chair, across tables in dozens of countries. Face to face with the professionals who install what we make — not to present, but to listen. To watch a stylist's hands work. To hear the complaint no client would ever put in an email.And to ask the question most suppliers never think to ask. Not how does it look on the shelf — anyone can win on day one. What did it look like the day she took it out ? That is the only honest test in this trade. Ten, eleven, twelve months in — after the colouring, the heat, the sea water, the hundred washes — is it still hair she was happy to have on her head? Every answer he collected went back to the workshop, and came out again as a better product.That is how a specification becomes a standard, and how a standard becomes a reputation — one that today carries our work into the hands of brands, wholesalers, and salons around the world.
Haiyi Hair now reaches professional clients in over 100 countries — Genius Wefts, K-Tips, Tapes, Clip-ins — carried by technical depth, stable quality, and a reputation earned one repeat order at a time.
The tools have changed. The scale has changed. The man's standard has not:It should never feel like something she is wearing. It should feel like hair she was born with — and it should still feel that way a year later.His father proved this material was worth a life's work. Mr. Cao has spent his own proving how far it can go — and he still walks the floor every week to make sure it does. Mr. Cao has never known a life without hair — he grew up in the courtyard where his father sorted it by hand in 1992, and worked every job on the floor of the factory that became Haiyi Hair. One standard has run his life ever since: it should feel like hair she was born with.
