How does shampooed hair fall apart in the water and stick together when it comes out of the water?

The most concise and intuitive answer is the best answer. Don't mention any free energy, it's too abstract. Hair is hydrophilic (that is, it attracts to water), it spreads out in water, which can be understood to some extent as hair dissolves in water; But unlike sucrose, which dissolves in water, it is peeled off in layers of water until the water is saturated.

If the hair is not hydrophilic (i.e. it repels water), then the hair will be surrounded by water and squeezed together, and the space between the hair will be air (I haven't seen it, I can imagine it, but it is easy to verify this if the surface of the hair is coated with a material such as Teflon). Hair is not air-friendly, and wet hair in the air is surrounded by air as an intimate whole and squeezed together, just as hair with Teflon is not hydrophilic and squeezed together by water in water. Whether it's close or not, how close it is, who is closer, it's worth saying it with freedom at this time.

It is wrong to simply attribute to adhesion, where adhesion accounts for less dominant factor. It is mainly determined by the wetability of the hair. The latter explanation is basically correct.

One thing is certain, that is, hair is hydrophilic and can be completely wetted in water, so its viscous resistance in water is less, which is the main reason why hair can move near free movement in water. After leaving the body phase, if the moistened hair is to be dispersed from each other, a new liquid-gas interface needs to be formed between the moistened hair, and the formation of the new interface requires work, and the lack of work conditions naturally cannot be dispersed. Infiltration, the surface tension is minimal, and the surface area of the N hairs is reduced by n times compared to the surface area of the N individual hairs, so the hairs are bonded together by the surface tension.

Your hair type should be fine and soft, and if it is, then you don't have to worry, it's a normal effect.

Is your hair curly or just permed It is recommended that you use Pantene's Smoothing or Repair Series to wash it more and be sure to rinse it clean There will be no problem, if it really can't be solved, you can cut your hair short and try to grow a new one.

I think I often go to these ** to study, search for Tu Niu Niu.

Under normal circumstances, people will be more refreshing after washing their hair, their hair is also very clean, and the whole person will feel better, but some people have sticky hair when their hair is wet, which may be caused by not washing their hair, such as not using the right shampoo, or the water temperature of washing hair is not right, etc., in addition, the following factors should be considered in this case.

Now there are a variety of shampoo products on the market, and when you take a bottle in your hand, almost all of them have "dimethicone" written on the ingredient list, and this substance is often called "silicone oil".

Silicone oil is insoluble in water in liquid form, but it is soluble in grease. Although the hair feels good to the touch after use, due to the chemical nature of the silicon itself, it will cause the cuticle to close and prevent the hair care products that are used afterwards from entering the hair. If you don't wash your hair properly when shampooing, it may adhere to the scalp and cause problems such as oiliness and hair loss.

For some people, regardless of whether their hair is clean or not, they must wash their hair once a day, and some people will wash it once in the morning and once in the evening. We all know that if you don't wash your hair for a long time, your scalp will be oily, but if you wash your hair too often, it will also be oily.

The reason is that sebum is secreted according to the balance of water and oil in the surrounding environment, and frequent washing will wash off the sebum that should be on the hair, so the body will get a signal of "lack of oil", and then further secrete oil to balance the entire scalp environment, and so on, the hair will become more and more oily. When the hair gets wet, it sticks together and can't be separated.

This is due to:Surface tensionrole.

Any force that acts on the surface of a liquid, reducing the surface area of the liquid, is called liquid surface tension. The reason for this is that there is a thin layer on the surface of the liquid in contact with the gas, called the surface layer, and the molecules in the surface layer are sparser than the inside of the liquid, and the distance between the molecules is larger than that inside the liquid, and the interaction between molecules is manifestedGravitational force

For example, if you want to pull a spring apart, the spring will have a tendency to shrink.

ThereforeThe mass is smaller and softerThe strands of hair are bound together by the surface tension of the liquid. In fact, where there is water, there is surface tension, which is generated by wet water between chopsticksInfiltrationIt's also surface tension, but at this time we don't feel that the chopsticks are difficult to separate because of the surface tension, and that's because of the chopsticksBig and hardIt's just better to force them apart than hair.

Is the hair dye cream used to be bad, I used to dye my hair well. It is recommended to wash your hair before taking a shower, and then apply a thick layer of conditioner hair mask, tie it up or wear a hat. Then wash your body, take a shower and finally rinse off the conditioner...You can prepare a leave-in hair mist.

I usually spray it when I have nothing to do, but now it's best to let my hair dry naturally in the summer.

Just blow it off with a hair dryer. When you wash your hair, it all come together, because there is water, and the water will connect each strand of hair together. So the feeling is sticking together, but there is no hope that it will help you.

If you have a very boring but oily scalp, choose a moisturizing conditioner and don't touch your scalp.

As long as there is water, it will stick together because of the surface tension.

Strands of hair are subjected to the surface tension of the liquid and stick together.

Because hair has good stickiness, it is not easy to separate.

Some hair dye creams are of poor quality and hurt the hair.

When the hair is in contact with the water in the water, the water is continuous, the hair is scattered, when it comes out of the water, because of the gravity of the hair and the water are in a drooping state, the hair moves upward under the force of the head, the liquid water in the hair will flow down under the action of gravity, the outflow of water is continuous, with the flow of water, the gap between the hair is getting smaller and smaller, and the air cannot enter, the hair will be in a bundle. After the void is small to a certain extent, it will produce a siphon phenomenon, and the water will not flow downward, but will be attached to the void around the hair, so it will stick together, and after leaving the body phase, the moistened hair needs to be dispersed between each other, and a new liquid-gas interface needs to be formed between the moistened hair, and the formation of the new interface needs to do work, and the lack of conditions for doing work naturally cannot be dispersed. <>

Because hair is most fragile when it is wet, if you dry it vigorously, it will break or knot, so after washing your hair, it is best to wrap it in a towel and blot it dry, comb it all forward with a wide-toothed comb, and dry it with a hair dryer, from the roots to the ends, which is relatively less scorching. But when blowing your hair, the mouth of the hair dryer should be 15 cm away from the hair, otherwise the hair will be over-dry. Washing your hair every day not only does not protect your hair, but it can also cause damage to your hair.

Because washing your hair too often will completely wash off the oil secreted by the sebaceous glands, so that the scalp and hair lose their natural protective film, which is not good for the health of the hair. Since the hair follicles open when shampooing, conditioner is applied to the hair roots, and the chemicals in it tend to seep in and clog the hair follicles. It is recommended to detangle your hair first, apply it along the tips near the ears and make sure that the conditioner does not touch the scalp.

The oily, waxy substance produced by the sebaceous glands inside the hair follicles of the scalp is sebum, and when the sebaceous glands secrete too much sebum, these substances can spread to the hair, making it look greasy. The longer the hair, the more it sags under gravity, and the more the roots are strained, making it more likely to be oily and flattened. It is recommended to trim your hair at least once a month, which can not only help control oil, but also have a certain protective effect on the hair roots.

When washing your hair, don't wash off the shampoo immediately, you should gently massage the scalp with your fingertips for at least 30 seconds before rinsing again, which will help wash away the excess oil. If your hair is oily, you can also repeat the wash to make sure your hair and scalp are clean. <>
