What a salon hair treatment does

Salon treatments replace lost protein and moisture inside the hair and seal the cuticle, making it softer, shinier and stronger. They are especially helpful after bleaching, perms, sun, sea water or long flights.

How a treatment appointment works

  1. Hair diagnosis

    We check porosity, elasticity and damage to choose the right formula.
  2. Clarifying wash

    A gentle cleanse removes build-up so care can absorb.
  3. Treatment layers

    Proteins, lipids and moisture are applied in sequence.
  4. Heat or steam infusion

    Gentle heat helps the treatment penetrate.
  5. Seal & rinse

    An acidic sealer closes the cuticle for shine.
  6. Blow-dry finish

    A smooth blow-dry and tips for home care.

Keep hair healthy at home

  • Use a sulfate-free, moisturising shampoo.
  • Apply a leave-in conditioner or oil to the ends after washing.
  • Always use heat protection before irons.
  • Book a treatment every 2–4 weeks if your hair is bleached or very dry.
