1 \ People just got up in the morning and their blood circulation has not returned to normal level. The blood flow is slow. When washing your hair in the morning, because the skin of your head is sensitive, the stimulation of water will suddenly accelerate blood circulation.
Therefore, a sudden increase in blood speed will make the other person's head feel uncomfortable.
2 \ Wash your hair at night, because the air humidity is relatively high at night, and it is not easy to completely dry your hair. When sleeping, because the skin of the head is close to the pillow when sleeping, the residual moisture can not be ventilated and dry. Therefore, water can only be evaporated by body temperature, which constantly erodes the skin of the head and causes discomfort to the skin of the head.
Suggestion: It is generally better to wash your hair in the afternoon.
If you can't wash your hair normally because of work, please don't wash your hair when you get up in the morning, because all your organs are awake at this time, and sudden stimulation will cause discomfort. If you wash your hair at night, try to wash it as early as possible and try to dry your hair before going to bed.
Scientific shampoo
Before washing your hair, comb your hair, then soak it in appropriate warm water, and choose the appropriate shampoo according to the greasy degree of your hair. Shampoo containing protein should be selected for dry hair; Weak alkaline shampoo should be selected for oily hair; It is best to use shampoo containing resorcinol or sulfur for dandruff, such as 2% ketoconazole lotion or selenium disulfide lotion. Don't wash your hair with alkaline soap or washing powder to avoid hair deterioration, brittleness or even breakage.
When washing your hair, the correct way is: after wet hair, pour the shampoo suitable for your hair into your palm, gently knead it until it bubbles, then gently apply it to your hair, gently massage your scalp with your fingers, and don't scratch it with your nails to avoid damage to the keratin on the scalp surface; The focus of shampooing should be the hair that secretes oil; After gentle rubbing, rinse thoroughly with clear water to avoid leaving shampoo on your hair.
The process of drying hair is also very important. People always like to rub their wet hair repeatedly with a dry towel, and sometimes pat their wet hair, hoping that this will make their hair dry faster. As we all know, after the hair roots are soaked in hot water and massaged, the blood circulation is accelerated, the pores are opened, and the hair is easily broken. The correct way is: after washing your hair, use a large dry towel to absorb as much water as possible, gently comb it with a big comb, and then dry it naturally. If you need to blow dry your hair with a hair dryer, use a soft file, and the air outlet is 10 cm away from your hair.
After the hair is washed dry, you can use a proper amount of conditioner. Because the conditioner contains cationic surfactant, it can form a film on the hair, reduce the friction between the hairs, and make the hair smooth, bright and elastic. It is more suitable for oily hair, curly hair and long hair, and is also beneficial to hair maintenance.
The interval between shampooing is not uniform, but it is appropriate to wash your hair 1-2 times a week. It's hot every day in summer, you can wash your hair more often, oily hair more, and less in autumn and winter. You don't need to use shampoo to remove sebum excessively every day. On the contrary, it is more likely to cause sebum exuberance, aggravate hair oil, and cause hair to fall off easily. Therefore, daily shampooing only needs to wash away dust and sweat with warm water.
