Precautions:

1 Scratch your scalp with your nails when washing your hair: Many people like to scratch their heads with their nails when washing their hair, but there are actually many bacteria in their nails. Once the delicate scalp is scratched, it is easy to get infected. When applying shampoo, gently push your hair with your fingertips. In fact, the effect is very good, which can not only decontaminate but also promote blood circulation.

2, conditioner applied to the hair roots: Because the hair follicles have been completely opened when shampooing, the conditioner is applied to the hair roots at this time, and the chemicals inside are easy to penetrate and block the hair follicles. So after washing your hair, straighten it first and apply conditioner to the ends of your hair along your ears. It is best not to let the conditioner touch the scalp, so as not to block the hair follicles.

3. Sleeping with wet hair: Many female friends fall asleep before their hair is completely dry in order to catch up with time. In fact, when the hair is wet, the hair scales are completely open. At this time, the hair is fragile and not resistant to friction. If the hair sleeps in a semi-wet and semi-dry state, the cuticle will become thinner and thinner, which will make the hair drier and drier. Moreover, it is easy to cause harm to the body, and the invasion of moisture will make the body wet.

4. Wash your hair directly without combing your hair: Scalp is very important to your hair. Before washing your hair, comb your hair with a wet comb to let the dirt and dust attached to your scalp surface, so as to thoroughly clean your scalp and hair. In order to avoid hurting the scalp, you should use a comb with wider teeth or a round head.
