Keratin is a treatment that can temporarily smooth your hair by means of application of a special formula. It applied to clean, wet hair and is activated with a flat iron.
The formula covers the hair surface with keratin protein, making your hair look shiny, strong, soft and beautiful. As it was mentioned, it’s a permanent salon service, so your dry, damaged hair can become smooth for about 2-4 months until the formula is gradually washed out.
It should be also noted that this salon service has a cumulative effect, that is, the more often the keratin treatment is used, the stronger the hair becomes.
