The frequency of hair washing in winter should be 1-2 times less than that in summer. If you wash your hair every day, you can reduce the amount of shampoo or use it every other day to reduce the damage.
What should we pay attention to before and after shampoo?
In addition to the number of shampoos, the scientific nature of shampoo is also very important. People who can wash their hair every day will not do much harm to their hair. Even if they don't wash their hair many times, the harm of washing their hair once will be as bad as others' washing several times. Here are some tips for shampoo:
1. Do not use too irritating shampoo. This is different from person to person. After washing your hair, you feel itchy, astringent, dry or unclean, which means that this shampoo is too alkaline for you and needs to be replaced with a softer one.
2. Do not pour shampoo directly on the scalp. The normal way is to pour shampoo into the palm of your hand and rub the rich foam before shampooing. You can wash your hair more fully and reduce the residue of shampoo.
3. Do not overuse shampoo. The problem of shampoo residue needs to be paid attention to. If you use a lot of shampoo every day, you may leave some shampoo on the scalp every day. As time goes on, the damage to the hair is quite large.
4. Don't wet your hair, comb your hair and sleep. When the hair is wet, the hair scales are open. At this time, the hair is very fragile and can't bear friction. If you comb your hair and sleep at this time, the hair scales are terrible and the hair loss will increase obviously.
5. Do not scratch your hair with your fingernails. The correct way is to gently push the head skin with the finger abdomen, which not only decontaminates but also promotes blood circulation. Because there are many bacteria in the nail, once the delicate scalp is scratched, it is easy to induce infection.
6. Wash your hair less during illness. During this period, people's body resistance is poor. When the water on the scalp evaporates, it will absorb a lot of heat. If it is not handled properly, it is easy to have headache and cold.
