A keratin treatment smooths the hair’s surface and makes it easier to style. It does not straighten the hair permanently - it removes much of the frizz and shortens the time you spend in front of the mirror in the morning.

Who is it suitable for?

  • Hair that gets frizzy in humid air
  • Thick or wavy hair that takes a long time to blow-dry
  • Hair that feels coarse after colouring

How it works

The hair is washed with a deep-cleansing shampoo, the product is worked in strand by strand, and heat then seals it in. Allow a few hours, depending on the length and thickness of your hair.

The first few days

Always follow our instructions about how long to wait before your first wash - this is when the result is determined. Then use sulphate-free shampoo; otherwise, the treatment will wear off faster.

How long does it last?

Usually a few months, and it fades gradually rather than ending abruptly. How often you wash your hair has the greatest impact.

Keratin treatment and hair extensions

If you have hair extensions, the treatment must always be applied so that it does not come into contact with the attachment points. Tell us about your application when booking, so we can plan the order correctly.
