Negative ions keep your hair moist to the ends.
(Causes of hair to be worn)
Hair is parchment due to being scratched by the outer layer of the hair "cuticle".The cuticle is a layer of flat cell overlapping like a scale, which is easy to damage when positive ions occur in the hair such as static electricity, and the hair will lose its luster and keep moisture away from the inside of the hair.
[Negative ions for moisturizing hair]
Negative Ion Dryer neutralizes positive ions by spraying negative ions into the hair to reduce static electricity, thus reducing cuticle scratches and peeling, making the hair easier to bind and maintain a pleasant texture.In addition, since it retains the moisture of your hair compared to ordinary dryers, it is especially recommended for those who are concerned about hair residue.
