Evaluation of Changes and Characteristics of Hair According to the Application of the Hair Dryer Plasma Functional Module

Abstract

Hairdryers are commonly known to cause hair damage such as “roughness”, “dryness”, and “hair color loss”. while using it. So, numerous studies have tried to find ways to dry hair with no damage or minimized level. In this study, we examined hair damage levels by varying drying applications during the process and analyzed hair changes either in essential characteristics such as “oil and moisture balance” or “microstructure”. As a result, hair was severely damaged when treated with a general hot air dryer for 90 minutes, causing cuticle crack or layer separation. In contrast, the plasma hairdryer caused just a little or even no damage to hair for the same exposure time. It may be because ions and moisture molecules generated when using a plasma hairdryer can protect hair structure from the harsh hot air condition.
