Although, in recent years, China Health Education Association is carrying out a publicity campaign of "Clean your hair every day and seize the moment of success", suggesting that people develop the hygienic habit of washing their hair 4-7 times a week. And a lot of scientific research has proved that washing your hair every day can keep your hair clean and healthy, and make it beautiful and smooth. But there are still many misunderstandings about whether it is necessary to wash your hair every day.
One of the misunderstandings: washing your hair every day will make your hair dry and yellow.
Some people worry that washing your hair every day will wash off the oil on your hair and make it dry, yellow and unkempt, but most medical experts think this worry is unnecessary. Because there are about 144- 192 sebaceous glands per square centimeter in normal scalp tissue, these sebaceous glands continuously secrete oil every day. Therefore, if it is normal hair cleaning, it will not only damage the hair, but also stimulate the normal secretion of sebaceous glands, maintain and adjust the balance of sebum, and make the hair shiny and elastic. On the contrary, excessive sebum can easily cause the accumulation of dirt and dandruff, block hair follicles and sebaceous glands, affect the normal secretion of sebum, hinder the nutrient absorption of hair roots, make hair yellow and dry, and even cause hair loss in severe cases; Dirty hair is likely to become a hotbed of harmful microorganisms, causing inflammation of hair follicles and sebaceous glands.
Especially in summer or people with oily hair, their hair is greasy and sticky because of the exuberant secretion of skin oil. If the grease remains on the hair for a long time and cannot be cleaned in time, it will be easily contaminated with dust and dirt, resulting in uneven hair surface and dull hair quality, which will increase the friction between the hairs and easily cause hair quality damage, split or even fracture when combing the hair. Therefore, washing your hair every day can remove dust, dirt and grease from your hair, effectively reducing the chances of split hair and broken hair.
Myth 2: Washing your hair every day will increase dandruff.
Some people are afraid that washing their hair every day will increase dandruff. In reality, dandruff seen by the naked eye is a normal metabolic product in the process of scalp keratinization, which is constantly falling off with the metabolism of the skin. In general, when the body or skin function is abnormal, dandruff will increase significantly. Dry skin and dandruff caused by insufficient water are white and dry. Medical research believes that the reasons for the increase of dandruff are very complicated, which may be residual substances such as hair gel and shampoo. Or the clinical manifestations of seborrheic dermatitis and fungal infection. Lack of B vitamins, mental stress and excessive brain use can also lead to an increase in dandruff, but the increase in dandruff is not necessarily related to shampoo.
Myth 3: Does shampooing every day lead to hair loss?
There is no scientific basis for saying that washing your hair every day will lead to hair loss. Hair roots grow in the deep dermis of the skin. Normal shampooing only cleans the hair surface and can't damage the deep hair root tissue. And if the number of hair loss per day is only 50- 100, it belongs to natural hair loss. Even hair loss during shampooing is mostly caused by improper use of shampooing products or rough cleaning methods, which has nothing to do with shampooing itself and shampooing frequency.
If you want to have elegant and beautiful hair, you need clean and tidy hair as the foundation first, and then you can get fashionable and avant-garde hairstyle. Therefore, from the medical and aesthetic point of view, cleaning hair is the most basic and critical step in hairdressing and hair care. Wash your hair frequently, remove the dirt on the hair surface in time, and remove the culture medium of germs, which can obviously reduce the generation of dandruff and increase the smoothness and combing ability of your hair. Therefore, washing your hair often will not only make your hair dry, yellow and fall off, but also make your hair more shiny and elastic. Therefore, the best way to keep your hair healthy and beautiful is to wash your hair regularly.
Advice from medical experts
Medical experts suggest that everyone should choose the number of shampoos per week according to their hair quality, season and activity space. There are about 654.38 million hairs in the human head, and the roots of each hair follicle are closely connected with sebaceous glands, constantly secreting sebum. If you have oily hair in summer or because of exuberant sebum secretion, your hair is greasy and thick, and it is easy to knot and not supple, then you should wash your hair 1 time every day in summer and oily hair to ensure your hair is clean and healthy. For people with neutral or dry hair, the frequency of cleaning hair can be adjusted to 4-5 times a week. If the temperature rises or people often exercise outdoors, their hair is easily stimulated by strong ultraviolet rays and dust in the air. In order to avoid hair damage, it is also advisable to wash your hair every day.
Although washing your hair every day and increasing the frequency of washing your hair is beneficial to hair health and beauty, how to wash your hair scientifically is the key to hair care and hair care. If the shampoo product is used improperly or the wrong shampoo method is adopted, it will not only effectively clean and care for the hair, but also damage the hair. For example, hair becomes loose when it meets water, so wet hair is more easily damaged than dry hair. Therefore, before washing your hair, you can comb your hair with a dry wide-toothed comb and brush off the dust on the hair shaft, hair roots and scalp in turn, which can obviously reduce the amount of hair loss when washing your hair.
When washing your hair, choose soft water with low mineral content, and the water temperature should not be too high. Generally, you can choose warm water of about 40 degrees Celsius. Soak your hair first, then pour shampoo into your palm, rub foam on your hair, and gently insert it into your hair with your hands. Rub the hair roots and scalp with your fingertips. Never scratch with sharp nails. When the hair ends are tied, gently pinch them with your fingers and then rinse them with warm water. Then gently absorb the water with a dry towel, and it is not advisable to blow dry your hair hard. Finally, use a hair dryer to blow your hair to 80% dryness.
Because modern shampoo contains various chemicals, improper use is likely to have a negative impact on hair. Therefore, you must be careful when choosing, and try to choose some high-quality, gentle and effective shampoo products suitable for your hair quality to avoid damage to your hair during use. After using shampoo, be sure to rinse it with clear water in time. If there is still a small amount of shampoo in your hair, you can remove it and neutralize it with conditioner. Authoritative experts in European dermatology have made a comprehensive review and evaluation of shampoos on the European market, and finally come to the conclusion that as long as high-quality shampoos are selected, hair will not fall off and will not be harmed. This also shows the importance of the quality of shampoo products and reminds people not to use some fake and shoddy products for the sake of cheapness.
Cleanliness of hair is the foundation of hairdressing, so it is necessary to wash your hair frequently from the perspective of beauty and hairstyle shaping. There is a famous basic principle in cosmetology, "decrease first and then increase", that is to say, the process of any beauty salon must be cleaned first and then maintained. Only on clean hair can a fluffy, elegant and energetic hairstyle be supported. Hairstylists often say that "the roots of hair are not straight, and the ends of hair are indecent." It is difficult to make all kinds of ideal and beautiful hairstyles on hair covered with grease, dust, dirt and pressed hair roots.
China Health Education Association put forward a brand-new concept of healthy hair care, that is, "Clean your hair every day and grasp the moment of success", and advised people to follow the correct method of shampooing and develop the hygienic habit of shampooing 4-7 times a week. This is quite different from our habit of washing our hair every three to five days. Everyone's hair needs cleaning and care, but what are the benefits of washing your hair often? How often do we wash our hair is healthy and beneficial?
