How to choose ordinary shampoo, silicone oil-free shampoo and amino acid shampoo?

These three shampoos should be the most commonly used by immortals, namely, ordinary shampoo, silicone oil-free shampoo and amino acid shampoo. So what's the difference between these three shampoos? After a rough analysis, you can't read it anyway, so you can't hit me. Too arrogant.

Everyone began to pay attention to silicone oil from the advertisement of a certain brand, and then silicone oil was attacked by various charges. I just want to say, why don't you have hair? Don't you count 13 in your mind?

Silicone oil is viscous and plastic, and has moisturizing and supple effects on hair. Hair grows from the hair follicles of the scalp, and the main component is keratin. There are many uneven scales on each hair. When the hair scales are damaged, they will tilt upwards, which will increase the friction between hairs and make them tangled. More friction will aggravate the damage of the hair scales. When washing your hair, the silicone oil in the shampoo will adhere to the gaps in the hair scales, so that the hair surface will be filled and the hair will feel very soft.

What has been promoted is silicone-free shampoo. Do you have any hair conditioner without silicone? Maybe. How about baking ointment without silicone or hair mask without silicone? I don't think so. Because logically speaking, hair care products should make consumers feel that their hair is better, and of course they should make consumers' hair supple. If your hair is still rough after using it, and you say that your hair care products are good, then you are not kidding. Then how to make your hair soft, silicone oil.

Silicone oil is a macromolecular substance and will not be absorbed by hair follicles. There is not much silicone oil in shampoo. After all, silicone oil is quite expensive. How much is a bottle of shampoo? Under the cleaning effect of surfactant, and with a lot of water washing, it will not remain on the head. What is even more exaggerated now is the emergence of shampoo to prevent PM2.5. Alas, this is really a big brain hole, and the brain is easily contaminated with dust. So if we don't take an umbrella on rainy days, will the rain get into our heads?

Silicone oil has obvious hair care effect, especially for hair that is frequently dyed, and the damage of hair scales is more serious. Because the function of silicone oil is to attach to the hair and fill the damaged and open hair scales.

Silicone oil is safe for cosmetics because it is not irritating to the skin. Although it can form a hydrophobic film on the skin, it is breathable and will not cause acne, acne, hair loss, allergies and so on. On the contrary, it is often used in products marked A as acne-free or oil-free, which is its advantage over traditional oils.

Then the old irons will have questions. If you say silicone oil is so good, you should always use shampoo containing silicone oil. Everything has two sides, which is what we will talk about next.

Many old irons will find that when using shampoo, it feels good to use half a bottle of shampoo, but it is not so good later. A customer asked me face to face, is your shampoo generally good or not? Actually, it's not. When we wash our hair, it is still not enough in the end. It can't be as thorough as washing in a barber shop. So it is normal to have silicone oil residue. If silicone oil remains too much, your scalp will become oily, and your hair will probably be trampled and not fluffy. So many people often say that shampoo should be changed frequently. In fact, it doesn't matter whether it is changed or not, just change the effect. I often advise customers to buy two bottles of shampoo to moisturize and control oil. Wash your hair three times a week, you can moisturize it twice and use it once. So there is no feeling of scalp oil. However, again, the accumulation of silicone oil is not the root cause of hair follicle blockage and hair loss. The correct way to wash your hair is very important.

The silicone oil-free shampoo avoids the problem of silicone oil accumulation in silicone oil-containing shampoo. On the other hand, the separation of washing and nursing can make washing and nursing cleaner and nursing more in place. The use of silicone oil-free shampoo without conditioner will make the hair dry, as serious as a straw, and the shampoo experience is poor.

Silicone shampoo and silicone-free shampoo are used as surfactants for cleaning purposes. There is a sensational news at home and abroad. Many well-known brands of shampoo contain carcinogen dioxane. Where does dioxane come from? It comes from SLS/SELS surfactant. Pick up your shampoo and see if there are two ingredients, sodium lauryl alcohol ester and sodium lauryl alcohol polyether ester. This is SLS/SELS surfactant, which can be found in almost all shampoos in the supermarket. In the composition table, the arrangement order of components is arranged according to content, and the higher the content, the higher the arrangement. Sodium cinnamyl alcohol ester and sodium lauryl alcohol polyether ester are the main components with the highest content except water in shampoo. Dioxane is an impurity by-product left in the process of manufacturing SLS/SELS raw materials, and then brought into shampoo. Therefore, only by using more advanced raw materials and avoiding this big stimulus source can we completely avoid the introduction of dioxane and maintain scalp health.

At this time, amino acid shampoo was born like a savior. The real amino acid shampoo is made of amino acid surfactant. Without adding a little amino acid humectant or other amino acid components, it can be called amino acid shampoo. Amino acid surfactant is a cleaning ingredient only used in high-end facial cleanser at present. Does not irritate the skin and eyes, and is the most gentle to the skin. Long-term use will not harm the skin, and it is no problem for babies and pregnant women. However, the cost of amino acid shampoo is high, so the price is higher than the first two. Amino acid shampoos are all positioned at the high end. For example, instead of adding preservatives such as methyl nipagin, ethyl nipagin, methyl isothiazolinone, etc., which will cause secondary irritation to the scalp, a cosmeceutical antibacterial agent with low irritation and low sensitization such as phenoxyethanol is used.

How to choose shampoo depends on your mood. After all, you can't spend money to make yourself uncomfortable. Boys can choose shampoo containing silicone oil. After all, no boy likes to use conditioner, and hair without silicone oil is not supple. What about the hairstyle? What can you do to pick up girls? Girls can choose amino acid shampoo and use it with conditioner. Use shampoo containing silicone oil if you are afraid of trouble. Different people have different opinions. Just be happy.
