Throughout history, people have been looking for ways to curl their hair.
Perm is closely related to the development of perm tools. It can be said that the promotion of perm tools leads the development of perm.
In 1990s, North Korea invented ceramic ironing, and then it spread to Japan, Taiwan Province Province from Japan, and finally to Chinese mainland. This is a long process, and ceramic ironing has been popular until the beginning of the 20th century.
In August 2002, people began to popularize digital perm in SPA. This technology was invented by Meiyu Company in China, and it is also an independent research and development technology in China's hairdressing industry. It breaks the traditional perm method in the west, and outputs safe voltage with 24V less than 36V to supply power to people's heads, which greatly guarantees people's safety in the perm process.
Until now, no perm technology is more advanced, healthier and safer than digital perm.
