Get frizz-free smooth hair without having to use damaging heat like your typical straighteners. The ego professional Ego Therapy Cold Iron are a new breed of hair straighteners in that they are an electric treatment to mend your hair back to health, which in turn will give you naturally straighter sleeker hair.The cold irons use a combination of infrared technology and ultrasound that pulses through the cuticle at 36,000 times per second to increase the production of proteins and natural amino acids; both of which are needed to improve and maintain a healthy head of hair. ego Therapy also smooths down the cuticle as you use it to lock in the conditioning properties and keep hair looking smooth, shiny and flyaway-free. - K.RPlease Note: ego Therapy Cold Iron can be used on wet hair only.Supplied with a UK plug (230v)
