How often do you wash your hair is the most scientific
There is no strict regulation on how often to wash your hair. Theoretically, as long as it is suitable for your physiological habits and feels comfortable and healthy, you don't have to worry about the frequency of shampoo. Scientific and healthy shampoo frequency depends on different hair quality and seasons.
Oily hair
The sebaceous gland of oily hair secretes exuberantly, and the heat in summer will aggravate the oil production. If not cleaned in time, the pores will be blocked, not only the greasy hair will affect the image, but also you will feel very uncomfortable. Therefore, oily hair can be washed once a day.
dry hair
For dry hair, because of less sebum secretion, manic, dry, itchy and dandruff are the biggest enemies. Therefore, the frequency of shampoo should be reduced properly. Dry hair, regardless of season, should be washed once every 2-3 days.
Of course, you can't be lazy for a week because your hair is too dry. If you don't want to speed up the aging of your hair, even if it's still elegant and dry, you can't wash your hair for more than 3 days.
How often do you wash your head in winter
Generally, it is better to wash 2-3 times a week; if you are often outdoors, you can increase the number of times properly if you have a lot of lampblack and dust; and it doesn't matter if you rarely go out and your hair is not oily.
Wash your hair properly. Many people like to wash their hair with their heads down. However, long-term drooping of the head will affect the normal blood circulation, resulting in a lack of blood supply to the brain, which is also detrimental to hair growth. Therefore, when taking a shower, it's better to wash your hair upright, and adjust your body to the most comfortable state. When washing your hair, the water temperature must be moderate. Generally, the temperature is the standard, and 37 ℃ is the most appropriate.
Best time and water temperature for shampoo
The best time is after 12 o'clock
Theoretically speaking, from 12 noon to 10 pm this period is more suitable for shampoo. Office workers generally can't wash their hair in the daytime, so it's good to wash their hair before 10 o'clock at night. There's enough time to wait for the hair to dry completely, and then go to sleep.
There is also a theory that from 10:00 p.m. to 2:00 a.m. is the regeneration period and active period of scalp cells, so washing your hair before 10:00 a.m. and going to bed early after your hair is dry is not only good for your health, but also a trick for your hair.
The water temperature is about 40 degrees
Cold water shampoo is the most irritating to the scalp, which may lead to hair loss! Too hot water shampoo can also damage hair follicles, the best water temperature is about 40 degrees, and it can be slightly hotter than the body temperature.
