Causes of hair dryer damage to hair

　　1. The wind is unstable and easy to knot. Although many low -end hair dryers have multiple wind speed gears, their wind systems and technologies are backward, resulting in unstable, unevenness, or even too weak in winding wind. Such a hair dryer not only cannot effectively release negative ions, but also cause unnecessary pulling and chaos to the hair, such as entangled and knotting hair, which affects the neatness and beauty of the hair. Long -term use will also cause the hair to dry, fall off, change, change the hair Yellow and so on.

　　2. The penetration of negative ions. Many other products claim that they can use negative ions to raise hair and hair care, but in fact, their negative ion effect is not ideal because they ignore the penetration of negative ions. The penetration of negative ions depends not only on the number of negative ions, but also related to the quality, purity, concentration, and the output stability and attenuation of negative ions. If you simply increase the number of negative ions without considering these factors, then the negative ions cannot effectively enter the inside of the hair and achieve the purpose of hair care and hair care, but may cause damage to hair.

　　3. The temperature is not constant and easy to hurt. Although many low -quality hair dryers have multiple temperature gears, their temperature control systems and technology are not advanced, resulting in the inaccurate temperature, inaccurate, or even too high or too low. Such hair dryers not only cannot effectively release negative ions, but also cause severe damage to the scalp and hair, such as scald scalp, stratum corneum that destroys hair, dry hair, split, and falling off!
