How to use hair dryer does not hurt hair?

Shampoo way new knowledge: to wash in the bath shampoo, as far as possible the rise of the hair, do not face down. Because low head shampoo, the scalp is easy to slide down, short-term shampoo in this way will not have much impact. However, if the long-term use of bow shampoo, easy to make the face become relaxed, and even let the lines deepen. Shampoo should be completed before 10 p.m. We use hot water shampoo, due to the warm effect, so that the scalp blood capillary expansion, the body radiated to the surrounding heat increased, while the hair is wet, there is a lot of water evaporated, so it will take a lot of heat. Generally, when one gram of water evaporates, it takes 500 calories away. Due to increased heat dissipation, so that the body cold, and thus reflectively to the upper respiratory tract blood capillary contraction, Local blood flow reduction, lower resistance to the upper respiratory tract, the local virus or bacteria that already exist in the gap, growth and reproduction, resulting in upper respiratory tract infection, resulting in cold symptoms, such as runny nose, stuffy nose, headache and even fever. Therefore, do not wash your hair before going to bed. If you are too busy with work and wash your hair after 10 o'clock, you must dry your hair to sleep, otherwise you will get up the next day and your hair will not look good, but also hurt your body. After washing the head should not be naturally air-dried after each wash the head does not blow the head, wet hair roots are more likely to stick to dust and other substances, so that you have just washed the hair with more dust. Moreover, when the hair is in a wet state, the scalp horny is also in a relaxed state, so that the friction between the hairs is more obvious, which is more likely to cause the split ends of the hair. Therefore, it is best not to let wet hair dry naturally after each wash. Dry hair with a towel and blow dry two ways. Many people think that the hot air from the hair dryer will dry out the hair without shine, so they choose to rub it hard with a towel. If you use a towel instead of blowing hair, it is easier to hurt your hair, because the hair is most fragile when it is wet, you can't rub it hard to dry, and you can't shake your hair with a towel, otherwise your hair will break or knot. Therefore, I recommend that friends first use a towel to dry the hair to a certain extent, and then use a hair dryer to dry the hair to a certain extent. How to use the hair dryer does not hurt the hair wet hair scales all open, this stage of the hair is the most vulnerable time. Therefore, it is not suitable to direct the hot air stall of the hair dryer to the hair. The correct way is to wrap the hair with a strong towel that absorbs water, When the hair is no longer dripping water, hold the hair dryer high, hand over the head vertical blow dry hair, as long as the blow dry when the hair dryer constantly wandering, and pay attention to the distance between the hair to maintain more than 10 cm, the hair dryer is not harmful to the hair, hair blowing to 70 to 80% dry can be. There is still a trace of water vapor hair, can be gently combed by hand to be its natural air drying on it. Xiao Bian reminded that when blowing hair, it should be dried along the way of hair scale growth, that is, from the root.
