Thousands of hairs wrap around your head, naturally forming the head's first line of defense. Thick, healthy and clean hair can protect the head from external mechanical and bacterial damage, and plays an important role in fitness.

Sensory effect

The hair is quite sensitive. When the external environment has an impact on the human body, whether it is windy, rainy, or sun-bathed, the first thing to feel it is the hair. The information sent by it is transmitted to the brain, so that a variety of protective measures are taken.

Regulatory effect

Hair can play a role in regulating body temperature. In winter, the wind is cold and the blood vessels are constricted, so the hair can keep the head warm. In summer, the sun is scorching and the blood vessels are dilated, so the hair can dissipate heat. Therefore, hair has the dual function of both retaining heat and dissipating heat.
