It is reasonable to say that natural air-drying is more harmful to hair than hair dryer, because when hair is wet, the scales will expand and the hair will be very fragile. Long-term contact with water will mean more chances of hair damage. Recently, according to the research of foreign scientists, Air-drying hair naturally is actually more harmful to hair than using a hair dryer. ? He found that using a hair dryer at the right distance, at the right temperature and in an accurate step-by-step way can actually reduce the harm caused by hair drying. So they came to a conclusion that letting wet hair dry naturally is actually more harmful to hair quality than using a hair dryer correctly.

Scientist Moore explained:? When hair is wet, its fibers will swell and become more fragile. So long-term contact with water means a greater chance of hair injury, because this is its weakest state. ? Moore therefore said that it is good to minimize the time when hair is wet, but it must be dried in the right way to avoid causing more unnecessary harm.

Moore suggested that the following four steps should be paid attention to when drying wet hair:

1. Wipe your hair with a towel first, but don't wipe it horizontally between your hair, because it is easy to break at this time. 2. Spray heat-resistant spray on hair to form a protective layer to resist daily heat damage, protect scalp and hair roots, and prevent hair from splitting. When you blow your hair with a hair dryer, use a small fire at first, because high temperature will hurt your hair. After the hair is dry, you can gradually increase the heat of the hair dryer. When you feel your hair getting warmer, you can turn the hair dryer to the highest temperature and start styling.

From a health point of view, it is best to blow dry your hair after washing it. If it is wet for a long time, it will affect your health. Wet hair will evaporate slowly, and the scalp will become soft if it is soaked in moisture or excess water for a long time. When the hair is dry, it will be dry due to lack of water, and dandruff will occur after a long time. So no matter from which angle, as long as we master the correct method of hair dryer, hair dryer drying is more beneficial to our hair than natural drying, and we don't have to worry about hair dryer injury.
