Description

Technical Field

[0001] The invention belongs to the technical field of hairdressing equipment, and in particular relates to a crystal seamless hair extender. Background Art

[0002] Hair extension is a hair technology introduced from Europe. As the name implies, hair extension is to connect hair to your own real hair, instantly changing from short hair to long hair. The hair used for hair extension can be a wig or real hair. Different types of hair extensions have different ways of extension. Some types of hair extensions must be done by professional hairstylists, while others can be done by yourself, such as clip-in hair, etc.

[0003] There are three main methods of hair extensions popular in hair salons now: bonding extensions, button extensions and braided extensions. Each of these three methods has its own advantages. Among them, braiding technology is newer and more natural.

[0004] Button hair extensions are to divide the hair into small strands, and use special buttons to fix the long hair to be connected to the roots of real hair. The hair on the top of the head will naturally fall down to cover the buttons. However, this method of hair extension is less comfortable and can easily cause scalp itching.

[0005] The technology of braided hair extensions is relatively new, but because the braiding process is very cumbersome, it is a waste of time in actual use, and the braiding quality is difficult to control.

[0006] Most of the existing braided hair extensions have the following defects:

[0007] 1. Braided hair extensions waste time because of the cumbersome winding process.

[0008] 2. Since it is difficult to control the quality of the winding during the braiding process, the effect of the hair extensions varies.
