In fact, shampooing is shampooing, and hair care is hair care. The focus of the two is completely different! And not everyone needs hair care and moisturizing products. In fact, there is no need to use it for the sake of use!
Today, through this article, doctors will fully explain the difference between shampoo and hair care products, as well as the small steps to choose!
What is the difference between shampoo and hair care products? Because hair and scalp are different!
Scalp is a living tissue, whose main function is to isolate dirt from the outside world and avoid excessive evaporation of skin moisture to the outside world. Because it is living tissue, if it is injured by * * *, it will also cause inflammation such as redness, swelling, heat and pain. Scalp tissue may also be infected with bacteria to produce cellulitis, or infected with mold to produce dandruff and other problems
Therefore, washing your hair is basically washing your scalp, which can wash away the dirt outside and the waste produced by human metabolism. But it should be noted that don't over-clean. Preserving the natural sebum membrane of normal scalp can keep the scalp healthy.
Hair is dead tissue, which is a structure formed by keratin winding. Therefore, whether it is dyeing or perming, it may cause some damage to the hair, but after cutting off the damaged hair, as long as the scalp and hair follicles are healthy, healthy hair can still grow.
In the stage of shampooing, in fact, dirty hair only needs clean water, plus the surfactant contained in the shampoo used, which can be basically cleaned with a little rubbing. So shampooing should be a simple matter, not too complicated.
Why do some people need hair care?
But the oil in hair is mainly produced by sebum secreted by scalp. Therefore, the longer the hair is, the farther it is from the scalp, and the hair will be more likely to become dry due to insufficient oil. In addition, the hair at the end of the hair is also an old keratin structure, which is easy to be rough and forked.
If you have short hair, dry hair and no split ends, you basically don't need to use hair care products at all. With your natural sebum secretion, you can keep your hair bright and healthy.
However, people with long hair who often blow, dye, set and perm may need to use hair care products.
How to choose shampoo? Know what scalp you are first!
Among the ingredients of shampoo, surfactant is the most important. The composition of surfactants will affect the overall cleaning power and acid-base degree of products (because different surfactants have different applicable acid-base ranges). In order to increase the convenience of use, some products will add thickeners, while others will add spices to make people feel comfortable. Products should be kept stable and cannot deteriorate, and sometimes necessary preservatives will be added.
In many shampoo products, some possible nutrients are sometimes added, such as amino acids and vitamins (the most common is provitamin B5 )… but are these ingredients effective? In fact, it is still controversial, because shampoo products stay on the scalp for a very short time, and they will be washed off in just a few minutes, so it is usually not the focus of product selection.
The most important thing about shampoo products is that they can clean the scalp moderately, not under-cleaned, but over-cleaned. People with different scalp attributes have slightly different requirements for cleanliness. Below we divide the scalp into the most common types:
Hair oil on scalp: less than one day after washing your hair, you can see that your hair is obviously shiny and even has a feeling of collapse and greasy. Neutral scalp: Even if you wash your hair all day, it looks dull. Dry scalp: sebum secretion is little, the scalp may be rough due to excessive dryness, and the hair tips may be dry due to lack of oil. Scalp sensitivity: it is easy to itch and redden the scalp. Seborrheic scalp: local sebum secretion is abnormally increased, often accompanied by dandruff. Some people have more sebum secretion in the T-shaped part of the face except the scalp, accompanied by dry itching and desquamation. Some people may think that I have never chosen any shampoo in particular, so I am living well now. That's true. If your scalp and hair are healthy, basically most products are fine for you.
But from the doctor's point of view, no matter what kind of scalp, the principle of choosing shampoo is that it is best to have moderate cleaning power and try to avoid unnecessary substances that may lead to * * * *. Especially for people with sensitive scalp, the simpler the ingredients, the better.
What is a pure product? We can go back and think about it. What is the key to shampoo? Isn't it just to clean the scalp moderately, and then wash away some dirt on the hair by the way to avoid excessive cleaning, that's all? Therefore, surfactant is the most basic component of this kind of products, but after washing off the oil, it is easy to cause dry hair and electrostatic problems.
Shampoo products may also contain these ingredients.
A few products will make you feel smooth and supple after washing, so silica gel is added to make your hair less susceptible to static electricity and feel smoother. Some products will combine quaternary ammonium salt and some oil components to deal with static electricity, and also make the washed hair feel smoother.
The first thing to say is that silica gel itself is very safe, but from the perspective of "scalp washing", it is not necessary. Oil does not necessarily cause problems to most people's skin. Moderate oiling is meaningful to dry hair ends, but not to clean scalp itself.
Sometimes, in order to make the product look more advanced, some white and bright ingredients are added, such as titanium dioxide or zinc oxide, which is white powder. Adding mica can make the product look white and bright.
If we consider some ingredients that produce fragrance, these substances may produce * * * for people with "scalp sensitivity".
If you are a friend of seborrheic scalp, you'd better communicate with your doctor about the choice of shampoo. Doctors usually recommend choosing the right dandruff shampoo.
Four keys in the process of shampoo selection
Next, let me help you sort out the whole process of thinking and action:
The key to choosing shampoo is not how to claim the products on the shelf, but what kind of scalp you are. How to distinguish your scalp type? You can refer to the arrangement in the previous paragraph. No matter what kind of scalp, it is basically recommended to choose a mild and simple product. The best condition after shampooing is that the scalp is properly cleaned and will not itch and peel off because it is too dry. If it is seborrheic dermatitis or other scalp diseases, you should first go to a doctor for a complete evaluation, rather than relying on shampoo to solve it yourself! In addition, I want to share with you that in fact, most people don't need to use shampoo and hair care products. Why?
If you have short hair, you don't have to worry about dryness and split ends after washing your hair. In this case, all you need is a simple shampoo.
If you have long hair and the hair ends are easy to dry and split, you can actually use simple shampoo first, and then use appropriate hair care products to strengthen the moisturizing and moisturizing of the hair ends. If you use shampoo and hair care products, you really only need to wash them once, but at the same time, you only need to stick more products on the scalp, right?
In fact, maintenance is really not that complicated. The most important thing is to understand the basic skin physiology, and then try to return to the original, so that it is easier to choose products and reduce the complexity of the problem that the skin may be disturbed!
