Is daily shampoo good?

As for those who have views, just wash your hair once a week, they think it will make their hair healthier. This is really wrong.

Shampoo every day right or wrong?

Among us, there are those who have a tendency to be too clean. They wash their hands with soap several times a day, while this has been warned by some experts as a benefit. So for the story of shampoo, what should we wash our hair every day?

Dr. George Cotsarelis, Dean of the Department of Hair and Scalp at the Perelman School of Pharmacy, University of Pennsylvania said 'You may have heard a lot of advice that shampoo is harmful to the scalp. Excessive shampoo may also cause dandruff. Not necessarily so'.

People with extreme views on shampoo often say that the mucus on the scalp is a natural moisturizing therapy. That's fine and there's no need to use shampoo to clean them. In fact, this is caused by an increase in seborrhea of ​​the scalp.The slime is a better condition for bacterial growth , Cotsarelis said.

About dandruff scales, it is the accumulation of dead skin cells that overlap. While washing your hair regularly, these dead skin cells will be cleaned and of course, you won't see dandruff appear.

Do you have to do a good routine every day?

Besides, during hair washing, dead hair follicles are also removed. This helps stimulate the growth of a new hair follicle. This is an important benefit of shampooing, so Cotsarelis says he is not a fanatic about spacing the time between two washes.

However, if you own a hair that is not shiny or too dry, it may come from you washing your hair too much. This does not affect men very much because they often have short hair and use styling products. The dry and lack of hair will be overcome. In contrast, women or men who have a preference for long hair are a problem.

If you have long hair, regular shampoo can make your hair more dry and brittle. However, Cotsarelis said: 'It is only a matter of hair state. Remember that hair is dead cells. If you wash your hair and break them, you're not losing your hair. '

This is the crux of the problem, washing your hair too often makes essential fat components disappear. These coat the hair and make them look strong. Adam Friedman, Professor of Dermatology at George Washington School of Science and Health, says that fats cover the surface of the hair, reinforce and prevent them from breaking or splitting.

So, how often is a routine of shampooing supposedly reasonable? Both Cotsarelis and Friedman think that it depends on the person, and for each stage, washing it every 1 to 3 days is reasonable . ' I think most people can control their hair. Every time they feel their hair is dry and brittle, they will automatically adjust their hair less often , 'Cotsarelis said. As for those who have views, just wash your hair once a week, they think it will make their hair healthier. This is really wrong.

However, not without exception. Cotseralis says African-American women or men, some have curly hair and are tightly curled up by their natural hair follicles.'If this is the case, washing your hair too often can make your hair brittle and dry, of course it will break a lot. For them, it would be fine if one or two weeks of shampooing once. '

If you have long hair, consider the state of your hair.

Which shampoo should we use? There is a bad news for you. Cotsarelis said hair conditioner shampoo is advertised as making the hair look thicker and bulging, they use some potentially harmful chemicals, exchanging them for the hair will be more eye-catching. Besides some shampoo containing essence from plants, it is not necessarily harmful to everyone, however, Cotsarelis said he met some patients who were allergic to these essences.

'I know that some of you are also afraid of chemicals in shampoo. However, you know, big shampoo companies tend to test closely and control the content in their products well. You should not worry too much , "Cotsarelis said. 'On the contrary, I have seen many people start using homemade shampoos, probably from natural products like apple cider vinegar or soda. It's crazy because they are extremely harsh products of acidic and basic environments. '

In short, you should have a shampoo testing process and a certain frequency of shampooing. This will suit each person and depending on different hair styles. In some initial testing time, your hair, they will not be in good condition. So you know you should adjust your shampoo, increase or decrease the frequency. Until you feel satisfied with your hair, it's time to keep a stable routine.
