I'm selling this because I don't use it. Operation confirmed, works without problems. Hairbeauron® ExcelleMium 2D Plus Professional 【 Hairbeauron® 】 01. Liberates hair from damage. The effects of Bio-Programming® technology strengthen the hydration structure of hair proteins, protecting against heat damage. 02. Hair becomes more moisturized with use. With conventional dryers, hair loses its shine and becomes rough to the touch, but with Hairbeauron®, hair becomes moist and glossy the more you use it. 03. Transforms hair quality beautifully. It programs damaged hair, aging hair, and even natural hair quality, leading hair and scalp to an unprecedented beauty. 04. Beautifies skin quality and lifts the face. You can also use it as an innovative beauty device that "improves skin texture, increases moisture, and lifts the face" just by applying cold air, which is unthinkable with conventional wisdom.
