After the treatment

A keratin treatment smooths the hair's surface, reduces frizz and makes styling dramatically faster. Done at home by a private hairstylist, it becomes an afternoon on your sofa rather than an afternoon in a salon chair. It is available as part of a mobile hairstylist in Athens and a private hairstylist in Mykonos.

How long it lasts

Results typically last three to five months, depending on your hair, how often you wash it and how you care for it. It softens gradually rather than disappearing overnight.

Who it is for

  • Frizz in humidity: island summers and sea air.
  • Long blow-dry times: keratin cuts them down significantly.
  • Coloured hair: it adds smoothness and shine to processed hair.
Less time styling, every single morning, for months.

Aftercare

Use sulphate-free shampoo, avoid tying hair tightly for the first days, and follow the specific advice your hairstylist gives for the treatment used. Salt water and chlorine shorten the life of any treatment, so rinse after swimming.

What it costs

At home in Athens, keratin starts from €550. In Mykonos, our Nanocure keratin, with no formaldehyde, starts from €650 (excluding VAT). If you are also thinking about colour, read balayage or highlights first, as the order of treatments matters.

THE SHORT VERSION

Three to five months of smoother, faster hair, done at home. From €550 in Athens and €650 in Mykonos. See hair at home on the Riviera.
