Natural color, hair products are defined as the color of the hair itself. And only for real hair.
Natural color is not a fixed color, two different people, there will be differences in hair color. Hair colors of different races in different countries have even greater differences.
The natural color specifically referred to here is a processed Hair Bundles without dyeing. What appears is the color of the hair itself. Generally, the natural color of Asian hair is black-brown. Natural color is still very useful as a way to identify the pros and cons of wigs. Because the natural color can more intuitively show the various real states of the hair itself, such as whether it has been processed, whether it has been dyed, or bleached. Once the hair is colored (that is, the hair is dyed to make it close to its natural color), it is difficult to distinguish the original state of the hair. So when we are purchasing wigs and hair products, learning to see if the wig is natural color is a good way to identify the quality of the wig.
How to tell if the hair is natural color, or whether it has been dyed? There are two methods that can be used, one is washing. It's very simple. Wash real human hair and wig products with hot water, and you can add detergent to wash clothes and other detergents. See if the water color turns black. If it doesn't turn black, it's just a little yellow, basically it can be judged that there is no pressure. At least it is not cold dyed (a method of acid dyeing, which is easier to color, but also easier to decolor). Second, use a sharper blade to shave the surface of the hair. If the shaved color is not white or yellowish, it is abnormal.
In addition, it can be distinguished by looking at the color difference between hair tips and hair roots. Dyed hair is generally dark at the tips and relatively light at the roots. The opposite is true for undyed hair.
