How is keratin hair straightening done?

It is able to prolong the effect of keratinization.

Important! Sulfate shampoo can accelerate the leaching of protein from the hair structure, so it is highly undesirable to use it after the procedure. Sea water also does not prolong the duration of the procedure. But it is quite possible to protect yourself from the effects of salts using special serums that prevent the destruction of the active substance.

Moreover, it is possible to process exclusively regrown roots.
