Restore deeply, protect continuously

The REP22 Protocol is a professional leave-in deep restoring treatment designed for hair that has been significantly compromised by chemical services, heat or environmental damage. What makes REP22 unique is its leave-in philosophy: while the salon session delivers an intensive reconstruction phase, the leave-in active complex continues to work between visits — progressively restoring the hair fibre and building lasting resilience.

The result is a cumulative improvement in hair strength, softness and overall appearance that deepens with each session of the personalised programme.

Who it is for

  • Those with severely damaged hair from bleaching, colouring or repeated chemical services
  • Hair prone to breakage, split ends and loss of elasticity
  • Clients looking for a treatment that extends its benefits beyond the salon session
  • Those seeking a comprehensive, progressive rebuilding programme for damaged hair
  • Anyone whose hair feels permanently compromised and is difficult to manage or style

How it works

  1. Damage assessment detailed evaluation of the extent of hair damage, porosity and structural integrity to define the appropriate REP22 concentration and session spacing
  2. Preparation a gentle professional cleanse prepares the hair and opens the cuticle for optimal penetration of the restoring complex
  3. REP22 in-salon treatment the concentrated restoring formula is applied through the hair, working to fill and rebuild damaged areas of the cortex
  4. Leave-in sealing the restoring complex is sealed with a leave-in finishing step — meaning it continues working between sessions to progressively improve hair resilience and health

Cosmetic benefits

  • Progressive improvement in hair strength and resilience across the protocol
  • Reduced breakage and split ends throughout the hair length
  • Improved hair manageability and softness with each session
  • Hair that feels and looks more structurally complete
  • Extended restoration between salon visits through the leave-in active complex

Frequently asked questions

01
What does 'leave-in' mean in the context of the REP22 protocol?

Leave-in means the restoring complex is applied to the hair and left in place without being rinsed out. This allows the active ingredients to continue working beyond the salon session, extending the restoring action into the days and weeks that follow.

02
How does REP22 differ from other reconstruction treatments?

REP22 combines a professional in-salon application with the sustained benefit of a leave-in formula. This dual-action approach means you receive intensive reconstruction during the session and ongoing support between visits — making it particularly effective for progressively rebuilding damaged hair over a complete protocol.

03
Is REP22 suitable for heavily bleached hair?

Yes. REP22 is designed specifically for damaged hair, including hair that has been significantly weakened by bleaching, highlighting or repeated chemical services. The personalised application ensures the formula is matched to your hair's current condition.
