"Collect your hair, grow your hair", this is a very special way of selling, and it is also a very special kind of buying and selling.
In some rural areas, such shouts can be heard almost everywhere, and some people will grow their hair long just so that they can sell it for money in the future.
However, many people don't understand the act of hair harvesting, and think that hair is not a rare thing, so how can it be sold for money?
And there are some people who think that what the hell is used for these hairs, and will there be some more secret operations?
So today, I'm going to give you a science popularization, it turns out that the hair that has been taken away still has such a purpose.
The use of hair
First of all, let's talk about what kind of use hair has.
In fact, the use of hair is very wide, for example, we can often see some costume dramas, and the hairstyles in costume dramas basically require wig sets.
And these wig sets are actually made from recycled hair, that is, the hair can be made into a variety of different hairstyles, which is very realistic.
Not only wig sets are used in costume dramas, but in fact, in our real life, there are also some people who have thinning hair or hair loss due to various reasons, such as disease, or genetics.
At this time, they can improve their image and make themselves look more natural and beautiful through hair extensions.
Hair is used to make soy sauce saying
I don't know if you've heard of some of the claims that hair is used to make soy sauce.
In fact, there are some such claims, and some people have confirmed them through experiments.
They experimentally added the hair to an acidic solution, and then it did hydrolyze and smell some special smells, very similar to the smell of soy sauce.
After such an experiment, many people were shocked because it turned out that hair can really be used to make soy sauce.
And in this way, it also makes people realize that there may be a lot of safety hazards behind some of the foods we use in our lives.
For example, if our soy sauce is made with substandard raw materials, then there will be a great threat to our health.
There is a very big safety hazard in making soy sauce from hair.
Since hair is used to make soy sauce, it is only natural that there will be a very big safety hazard.
Because our hair is not an environmentally friendly material, it can be attacked by air pollution or other toxic substances.
And if our hair is used to make soy sauce, then these toxic substances will be easily "dissolved" into soy sauce, which poses a great threat to our health.
How to solve this problem?
So how should we solve such a problem?
First of all, we should pay more attention to the various foods we use in our lives, such as soy sauce and other condiments.
Secondly, we should require the relevant departments to carry out stricter supervision of the food production process to ensure that the raw materials used are safe and reliable, and will not pose any threat to our health.
Thirdly, there are ways we can improve our ability to distinguish whether the food we use is qualified and safe.
There may be a lot of hidden operations behind the act of hair removal, and we should also be cautious about such things.
Not only that, but we should also be aware that some of the foods and other items we use in our lives may have various safety risks.
Therefore, we should have a heart that dares to explore, but also have a critical heart, learn to think, learn to question, only in this way, can we better protect our own rights and interests.
Do you think there are any other uses for hair extensions?
