It's very cold in winter, so many girls will have a hair dryer to dry their hair after washing their hair. But after blowing for a while, do you find that the hair quality is obviously deteriorated, and even dry and hairy? In fact, it's necessary to learn the correct blowing skills.
Normal hair contains a small amount of water, in the outermost layer of hair there is a protective film called hair cuticle. As the outermost layer of hair, it not only determines the surface characteristics of hair, but also acts as a barrier to prevent the evaporation of water in hair and the invasion of the outside world. Hair dryer, especially hot air blowing fast or for a long time, will damage the hair skin, so that the scales of the hair skin will no longer cling to the hair, and the water will easily escape from the hair, making the hair yellow, dry and split. At the same time, heat blowing will also cause scalp water shortage, increase dandruff, and cause hair damage. Master certain skills to reduce hair damage caused by hair dryer as much as possible.
Wrap the towel with strong water absorption to absorb the water dripping from the hair. When the hair is no longer dripping, hold up the hair dryer and blow dry the hair vertically with your hands raised over your head. As long as you keep the air duct moving when you blow dry, and pay attention to the distance between the air duct and the hair is more than 10 cm, the air duct will not hurt the hair, and the hair can be dried up to 70-80%. It's better to choose cold wind instead of hot wind, which will cause less damage to hair.
Blow the roots first. Lower your head and turn your hair up. Shake your hair with your left finger, shaking and blowing until it's almost dry.
Blow in layers. Blow dry the lower layer of hair at the back of the head first, and then gradually blow upward. If you don't blow in layers, you will find that the hair on the surface is very dry, but the hair root inside is still wet.
Blow along the direction of hair growth. The hair scales of wet hair are open, blowing along the direction of hair growth will make the hair scales close, if blowing against the direction of hair growth will make the hair scales open, and the more blowing, the more fidgety.
Keep a distance. When blowing the hair, keep the hair dryer 15 cm away from the hair to avoid damage to the hair.
