now the weather is getting hotter and hotter. Many people especially like to wash their hair with cold water. As everyone knows, cold water shampoo has many disadvantages. It is not only harmful to our own health, but also easy to cause the loss of hair nutrition. So how to wash and maintain your hair correctly?
washing your hair with cold water does more harm
1. You can’t clean it.
in hot summer, many people like to wash their hair with cold water. They will feel very cool in the washing process, but the decontamination ability is much worse than that of warm water. In many cases, cold water can’t play a good role in cleaning the scalp. Especially in summer, we all know that summer is the vigorous season of human metabolism. Because there will be more oil from the scalp than in the past, we need to wash it with hot water.
2. It is not conducive to blood circulation.
cold water shampoo is very easy to inhibit blood circulation and make the scalp ischemic in a short time, which is very unfavorable to the growth of hair. In particular, some people like to wash their hair immediately after exercise. This can easily lead to abnormal intracranial vascular function. There will be dizziness, black eyes, vomiting and other phenomena during the attack. In serious cases, it may also cause intracranial hemorrhage, so we must pay attention not to wash our hair with cold water.
3. It is easy to stimulate the scalp
. In summer, people’s scalp temperature is relatively high. At this time, sudden contact with cold water is easy to produce strong stimulation. People who like to wash their hair with cold water in summer will cause rapid contraction of hair follicles, damage hair follicles and serious hair loss. Many people like to wash their hair with cold water before going to bed. They feel comfortable after washing, which is conducive to sleep. However, doing so will be more harmful.
in summer, the energy consumption of the human body is relatively large, which is easy to produce fatigue, and the immunity against diseases is relatively weak. Therefore, washing your hair with cold water before going to bed will make the water stay on the scalp, and the heat dissipation of the head will be cold. Over time, it is easy to lead to qi stagnation, blood stasis and blockage of meridians. If you sleep in an air-conditioned room after washing your head and blow your head against the cold air, it will be cold and hot, which is easy to cause headaches and colds. Therefore, Xiaobian suggests that no matter how hot the weather is, you must remember to wash your hair with hot water. Don’t be lazy and covet temporary coolness. Doing so for a long time will do great harm to your health.
4. Insomnia and dreaminess, causing cerebral thrombosis
if you wash your hair with cold water every day for a long time, it will not only escalate headache and pain, but also be accompanied by anxiety, dizziness, irritability, shortness of breath, panic, fear, tinnitus, sour back pain, insomnia and dreaminess, neck stiffness and other symptoms, Some people have obvious tenderness points on both sides of neck and occipital. Seriously, it may even lead to cerebral thrombosis due to the violent contraction of cerebral blood vessels.
therefore, it is not advisable for healthy people to wash their hair with cold water for a long time. Cerebrovascular patients should pay more attention. Remember not to wash their hair with cold water. If you want to cool down and refresh yourself in summer, you can use a towel dipped in some hot water to cover your face. The effect is as good as before, and it has no harm to the human body.
shampoo temperature should be 31 ~ 38 ℃. Water is too hot to damage the hair, making it brittle and easy to break; If the water temperature is too low, the effect of removing oil is poor, so it can not be cleaned. When replacing water, it should be noted that the water temperature of water used successively should be roughly the same, and it should not be cold before hot or hot before cold. Because the best thing is that warm water can expand skin capillaries and superficial dermal vessels, open sweat pores and promote the excretion of metabolic waste. Moreover, the decontamination power is stronger than cold water, especially the dust attached to the hair stem is easier to be removed.
five misunderstandings that must be vigilant in daily shampoo
1. Scratch the scalp with nails when washing hair
there are many bacteria in the nails. Once the delicate scalp is scratched, it is easy to induce infection. When wiping shampoo, gently push the scalp with your fingers to decontaminate and activate blood.
2. Go out immediately after washing your head
studies have found that the amount of ultraviolet radiation received by your hair is more than twice that of facial skin. Ultraviolet rays will make hair scales thinner and peel off. Go out immediately after washing your head. Ultraviolet rays are easy to cause hair breakage. If you go out, you’d better hold an umbrella or wear a hat to prevent ultraviolet rays.
3. Sleep with wet hair
when the hair is wet, the hair scales open. At this time, the hair is very delicate and not resistant to friction. If you sleep with your hair half wet and half dry, it will cause the cuticle to become thinner and dry.
4. Apply conditioner to the hair root
because the hair follicle is opened during shampoo, the conditioner is applied to the hair root, and the chemicals in it are easy to penetrate and block the hair follicle. It is recommended to straighten out the hair first, apply the hair tip along the hair tip near the ear, and be sure not to let the conditioner touch the scalp.
5. Wash your hair directly without combing
“how can you attach hair when there is no skin”. The scalp is very important for hair. Before shampoo, comb your hair with a wet comb to make the dirt and dust attached to the scalp float on the surface, so as to wash the scalp and hair at the same time. In order to avoid hurting the scalp, it is recommended to use a comb with wide tooth gap and round head.
how to wash your hair correctly
do not comb wet hair
just after washing your hair, the hair scales are still open. At this time, if you comb your hair too many times, it will cause obvious damage to the hair scales, and your hair will become very irritable after drying.
don’t scratch the scalp with your nails
don’t scratch the scalp with your nails during shampoo. Although it’s cool, it may hurt the scalp. The correct way is to gently press the scalp with your finger belly.
do not pour shampoo directly on your head
shampoo must be poured into the palm of your hand and rubbed evenly before washing your hair. If you wash your hair directly on your scalp, it will easily cause chemical residue, and the cleaning effect is not ideal (not conducive to foaming).
the water temperature is about 40 ℃,
cold water shampoo is the most irritating to the scalp, which may lead to hair loss! Washing your hair in too hot water will also hurt hair follicles. The best water temperature is about 40 degrees. You can feel a little hotter than your body temperature.
it’s better to wash your hair less
if the hair itself is not greasy, don’t wash your hair every day, because washing your hair will lead to the opening of hair scales, and there will inevitably be some loss in the process from opening to closing, so washing your hair every day is not conducive to better hair quality. However, some people have severe hair oil, so they can wash their hair once a day, because keeping clean is much more important than the loss of hair scales.
when washing your hair, your head should be slightly lower
when washing your hair with a shower, many people stand straight and wash. In this way, the impact of the water flow may cause more hair loss on the top of your head than in other places, so the better way is to lower your head to the level of the heart, which can reduce the impact on your hair and promote blood circulation on the head.
after washing your hair, be sure to dry
many people wait for their hair to dry naturally after washing their hair, which is actually not good. When people wash their hair, the hair scales of their hair are open. Opening means vulnerability, and some dust, bacteria and dirty things will take advantage of it. Therefore, after washing the head, it is best to wipe it with a towel until it is 60 or 70% dry to promote the closure of hair scales, which is more conducive to reducing the damage of frequent shampoo to the hair.
the correct way to wash your hair
1. First, you should choose the most comfortable water temperature. You can test the water temperature with your scalp, but usually about 40 degrees is the more appropriate water temperature, and then you can wet all your hair with warm water.
2, now the shampoo you prepared directly in the hair before, after, and so on five parts, so that shampoo can be more evenly arrived at the various parts of the head, we first clean the scalp, and then use the whole palm to rub the scalp, pay attention not to use fingertips, so that you can rub the soft scalp foam in the scalp.
3. When the hair is completely blistered, use your finger abdomen to strengthen the massage details. Never massage with your fingernails. It may scratch your scalp, so you must massage with your fingertips.
4, of course, if you want to clean it more thoroughly, or your hair is very long, you might as well use comb to comb the foam from the hair root to the tail, so that the dirt on the hair can be removed more cleanly.
5, next is to clean up the foam on your hair. You can use your fingers to follow your hair and pay attention to the inner hair. If you are doing what we say before, you can wash the foam off your hair very smoothly.
conclusion: shampoo is something everyone of us will do. If you wash your hair incorrectly, it will not only cause your scalp problems, but also affect your health. Therefore, we need to pay attention to washing our hair and use the correct way of washing our hair, so as to make your hair darker and brighter!
