1, how about washing your hair at night?
Hair is actually very difficult to dry. If you don't do it thoroughly, it will be harmful to your health, so it is best not to wash your hair at night.
Everyone knows that the scalp is very fragile. After washing the hair, the pores of the scalp will all open, and many bacteria will take this opportunity to breed on the scalp. Many people go to bed after washing their hair at night, which is easy to catch a cold and cause headaches after a long time.
If you wash your hair in the morning, on the one hand, you can keep your hair fresh and bright all day, on the other hand, from a health point of view, washing your hair in the morning can promote hair health. After washing the hair, the capillaries in the head are in a dilated state, which is very vulnerable to external stimuli. The yang in the head will condense when it is cold, the body will be frozen, and the capillaries will naturally contract, resulting in a decrease in blood flow in the head, which is very unfavorable for hair growth. How about washing your hair at night? Of course not. After washing your hair, your body's cold resistance will be reduced, viruses and bacteria will easily multiply and reproduce, and various cold symptoms will appear, such as sneezing, runny nose and stuffy nose.
Secondly, after washing your hair at night, wet hair will stick tightly to the pillow all night, and there is no room for free breathing, and your hair will gradually deteriorate. Especially in summer, most people take a bath before going to bed. On summer nights, we usually turn on the electric fan or air conditioner, which does more harm to our health and hair.
2. Correct shampoo method
Get ready before washing your hair.
Comb the tangled hair slowly from the end of the hair, then comb it from the root to the end, or even comb it head-down from the brain spoon, which can make the hair smooth, improve blood circulation and clean it with half the effort! It can also make the oil fully moisturize the hair on the whole scalp, and it can also brush off dead cells and fallen hair on the scalp. This step is very important, especially for people with dry hair. It can stimulate blood circulation and oil secretion, thus making hair more moist.
The frequency of washing hair is moderate.
You can wash it once a day in the south or in summer, or when you feel uncomfortable with too much hair oil. In the north, or in winter, two or three times a week is enough.
Wash your hair well.
You should wet your hair first, then pour the shampoo into your palm, dilute it with water, and then rub it from the pillow and temple and wash it clean. Never wash the original shampoo on the top of your head, let alone dry clean it, to avoid strongly stimulating the excessive secretion of sebaceous glands on the top of your head (fat-prone area). Don't scratch and wash your hair with your nails, but gently rub and wash your hair with your fingertips or palms. If the hair is dry, it is enough to use shampoo once when washing your hair. If your hair is oily, you should use shampoo more than once.
Wash your hair at the right time.
Don't leave shampoo on your head for more than 5 minutes and rinse it off as soon as possible. Wash your hair in the morning or evening, but don't wait until your hair is dry before going to bed.
When washing your hair, the water temperature should be from high to low
The water temperature is 30-40℃, so don't overheat. Too hot will make hair brittle and easy to break, too cold will have poor decontamination and greasy effect.
3. Wrong cognition of shampoo
Myth 1: 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 lead to 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, because the skin oil secretion is very strong, the hair is greasy. If the oil stays in the hair for too long and is not cleaned in time, it is easy to be contaminated with dust and dirt, resulting in uneven hair surface, dull hair, increased friction between hair, and easy to cause hair damage, split hair or even fracture when combing 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.
In fact, the dandruff seen by naked eyes is a normal metabolic product in the process of scalp keratinization, which is constantly falling off with skin metabolism. 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.
