Many people have the habit of washing their hair with cold water, especially male friends. Also, summer is here and the weather is very hot. We will feel very hot and uncomfortable when we return home. Some people will take a cold shower and wash their hair with cold water. But is it good to wash your hair with cold water? Many people ignore some of the disadvantages when washing their hair with cold water. Let’s take a look today.

Summer is here, and many people can't stand such hot weather, so they often wash their hair with cold water, feeling that it is refreshing and pleasant. But are you aware of the good things about washing your hair with cold water? Do you know about the dangers of washing your hair with cold water? Today we will take a look at what the dangers are.

1. Not conducive to blood circulation

Washing your hair with cold water can easily inhibit blood circulation, causing the scalp to be ischemic for a short period of time, which is very detrimental to hair growth. In particular, some people like to wash their hair after exercise, which may cause abnormal function of intracranial blood vessels. When an attack occurs, there will be dizziness, black eyes and vomiting. Severe cases may also cause intracranial hemorrhage, so be sure to pay attention.

2. Cannot be cleaned

Although people who wash their hair with cold water in the summer will feel cool, its ability to remove dirt is much worse than that of warm water. In many cases, cold water cannot clean the scalp very well, especially in the summer when the human body's metabolism is vigorous and the scalp produces more oil than before, so it needs to be cleaned with hot water.

3. Easy to irritate the scalp

The temperature of people's scalp is very high in summer. If it suddenly comes into contact with cold water, it can easily produce a strong irritation. People who wash their hair with cold water in summer will cause the hair follicles to shrink sharply, damage the hair follicles, and even cause hair loss. Many people like to wash their hair with cold water before going to bed, which is even more harmful. In summer, the human body consumes a lot of energy, is prone to fatigue, and has a weaker immunity against diseases. Therefore, washing your hair with cold water before going to bed will cause moisture to be retained in the scalp. The heat dissipated by the head will condense, which can easily lead to qi stagnation, blood stasis, and meridian blockage over time. If you sleep in an air-conditioned room after washing your hair, with your head facing the cold air, you will experience a mixture of cold and heat, which can easily cause headaches and colds.

4. Washing your hair with cold water is not good for your metabolism

Washing your hair with cold water will stimulate the contraction of the hair follicles of the scalp skin cells, which will greatly hinder the metabolism of the hair follicles. If this continues for a long time, it will easily lead to the atrophy of the scalp cell follicles and loss of growth ability. The hair follicles will also be unable to protect the hair roots, putting people who love beauty at risk of hair loss.

5. The best temperature for washing hair is 31-38℃

The temperature of shampooing water should be between 31 and 38 degrees Celsius. If the water is too hot, it will easily damage the hair, making it brittle, easy to break, and the hair quality will deteriorate; if the water is too cold, it will not be able to wash away the grease remaining on the scalp and hair. Therefore, it is recommended to use warm water when washing your hair daily.

6. Washing your hair with warm water effectively promotes metabolism

Warm water has stronger cleaning power than cold water because it can dilate the skin capillaries and superficial dermal blood vessels, open the sweat pores, and promote the excretion of metabolic waste, especially the dirt attached to the hair shaft can be removed more easily.
