Shampoo can be said to be done every day. If you don’t wash your hair in hot weather, there will be enough oil on your head to stir-fry.
However, the more common things are, the more exquisite they are. Various [taboos] emerge one after another. Today we chose the most common ones:
- Shampoo cannot directly contact scalp shampoo will lose hair if it is not washed clean. When washing hair, you cannot directly grasp scalp water with your hands. Add some beer and then wash your hair to remove dandruff.
Have you ever believed these statements? Today, Dr. Clove came to help everyone distinguish between true and false.
Shampoo cannot directly touch scalp?
Supporters of this statement believe that the ingredients of shampoo will stimulate the scalp. If you directly contact the scalp, the scalp will not be able to stand it. It is recommended to rub foam out of your hands before washing.
At first glance, it is quite reasonable. No wonder many people believe it.
But think about it and you will know… the manufacturer is really not a fool. If shampoo [is so powerful], wouldn’t it be used as an anti-riot weapon?
In fact, there are two points:
1. If you are allergic to the ingredients of shampoo, even if you rub the shampoo with your hands and dilute the shampoo with water, you will still be allergic when washing your hair, because allergic reactions are generally not related to the concentration and dosage of allergens.
2. Don’t worry about the so-called irritation. As long as it is a qualified shampoo of a regular brand, the irritation to the skin at the original concentration of the shampoo is small enough to reach the standard. Even if you pour the shampoo directly on your head, it is estimated that there will be no what problem. (Except for meat pain caused by waste)
Can you lose your hair if your shampoo is not washed clean?
Shampoo often takes the blame for alopecia, saying at one time that it cannot directly contact the scalp, and at another time that failure to rinse clean will cause alopecia.
What do you want from others?
Although some ingredients in shampoo, such as surfactants, may have slight irritation to the scalp, they are not enough to cause alopecia.
In fact, [not washed clean] this kind of situation is very difficult to occur, because the surfactant plays a cleaning role in shampoo, because the surfactant has both hydrophilic and lipophilic groups, it is easy to rinse off.
Unless you do not dry clean, you don’t need to worry too much.
Do not scratch your scalp with your fingers when washing your hair?
The answer may be a little unexpected-this question depends on how you wash your hair.
Let’s look at the scalp and hair to be washed off first. It’s what.
Scalp is the most exuberant part of human sebaceous gland distribution, secreting a large amount of [oil] every day. In addition, there are sweat on the scalp, dandruff caused by the replacement of keratinocytes, parasitic microorganisms, dust and other dirt in the environment. Hair is mainly environmental dirt, and there are no other dirt.
Therefore, the focus of cleaning should be scalp, then hair.
There are so many dirty things on the scalp, in order to ensure cleanliness, high-quality shampoo is an important part, and the action of grasping the scalp also has certain auxiliary effect.
It is completely feasible to cut short nails and properly grasp the shampoo skin with fingers on the premise of not damaging the scalp.
If your nails are very long, it is estimated that washing your hair and scratching your scalp are harmful only for you…
Can a beer shampoo remove dandruff?
No, even if it is washed directly with beer.
The reason is very simple. There is really no dandruff-removing ingredient in beer.
Beer is a drink made of barley malt, yeast, water and other raw materials. Its main components are water, ethanol, sugar, proteolytic products and a small amount of water-soluble vitamins.
General dandruff removal products can reduce dandruff in two ways: one is to kill Malassezia parasitized on the scalp, and the other is to inhibit sebum secretion of the scalp.
However, we have counted and found that the ingredients in beer have these functions.
Some people may say that alcohol can kill bacteria, but the alcohol in beer is generally only about 2%, which cannot kill bacteria at all. You can’t wash your hair with a high amount of liquor, can you?
In addition, although sugar, proteolytic products and water-soluble vitamins in beer have nutrition, they cannot be absorbed by human body through epidermis, and may also provide nutrition for Malassezia, which causes dandruff.
Therefore, if a person only uses beer to wash his hair and remove dandruff, it is unlikely that [snowflakes] will have the opportunity to see him every day.
