The only hair dryer in the world with the Active Oxygen activator: the exclusive UV lamp activates the air turning it into active oxygen. The drying process becomes a beauty and well-being treatment for hair. The active oxygen interacts with the hair colour molecules, promoting better stability and making the colour last longer; it facilitates the closure of the cuticle that makes the shaft smoother and brighter and protects the internal structure of the hair from weathering and heat; the oxidative process induced by active oxygen, destroys the bacterial capsule and improves the metabolism of the scalp, promoting its natural recovery. Ion generator with on-off switch that controls the emission of negative ions depending on the result you wish to obtain on the hair. Switch set on ION: to obtain hydrated, smooth hair and without static electricity. Switch set on O: to obtain volume and consistency. Includes 1 wide and 1 narrow concentrator nozzles Scientifically tested advantages: assessment test performed by Biomedical s.r.l. dermatology and trichology biomedical centre.
