Is it better to wash your hair with cold water or hot water

Washing hair is an issue that people take very seriously, because hair needs to be kept clean to look particularly beautiful, making people's image healthier and more beautiful. Washing hair is a relatively simple thing for most people, but if you want to wash your hair clean, you need some skills. For example, controlling the water temperature is a key issue. Let's take a look at whether it is better to use cold water or hot water to wash your hair?

The temperature of shampoo water should be between 31 and 38 degrees Celsius.

1. Water that is too hot can easily damage your hair, making it brittle and easy to break; water that is too cold (cool) can have a poor effect in removing oil stains and cannot be washed cleanly. When changing the water used, the water mix of the water used first and then the water used second should be roughly the same. It is not advisable to use cold first and then hot, or hot first and then cold.

2. Warm water is the best because warm water can dilate the skin capillaries and superficial dermal blood vessels, open the sweat pores, and promote the excretion of metabolic waste. Therefore, it has a stronger cleaning power than cold water, especially the dirt attached to the hair shaft is easier to remove.

3. If you wash your hair with cold water in the cold winter, it will cause a cold. Even in the hot summer, it will cause heat cold and other diseases due to the difference in head temperature.

4. Washing your hair with cold water on hot days can cause headaches. In summer, the temperature can be below 40 degrees, and in winter, it can be above 40 degrees. Because our body's senses are different in winter and summer. As for the problem of causing headaches, too high or too low water temperature can cause it, so it is better to keep it moderate.

5. It is best to wash your hair every other day in summer. Washing your hair every day will not only fail to protect your hair, but may also cause damage to your hair. Because washing your hair too frequently will completely wash away the oil secreted by the sebaceous glands, causing the scalp and hair to lose their natural protective film, which is not good for the health of the hair.

6. Some people who do special jobs still have to wash their hair every day due to hygiene requirements. But no matter who you are, you should pay attention to the choice of shampoo when washing your head. Avoid using shampoos with too high alkaline content. It is best to add conditioner. People who have the habit of washing their hair at night should try to change this habit. Secondly, they should dry their hair after washing, or blow dry it with a hair dryer to ensure that it is clean, relaxed, and healthy.
