TLDR Plasma hairdryers cause less hair damage than regular hot air dryers.
This study evaluated the effects of different hair drying methods on hair damage, focusing on the use of a plasma functional module in hairdryers. It found that using a general hot air dryer for 90 minutes severely damaged hair, causing cuticle cracks and layer separation. In contrast, the plasma hairdryer resulted in minimal to no damage under the same conditions. The protective effect of the plasma hairdryer was attributed to ions and moisture molecules that help maintain hair structure against the harsh conditions of hot air drying.
