Kerastase Fusio-Dose Strength & Reconstruction Set Booster + Concentre

Strength & Reconstruction Set

Concentré Resistance + Booster Reconstruction

For Breakage-Prone or Severely Damaged Hair
Protein Repair Therapy for Reinforced Strength

Restore strength and resilience to your most fragile strands with the Strength & Reconstruction Set. This intensive two-step treatment pairs the fortifying power of Concentré Resistance with the targeted rebuilding action of Booster Reconstruction. Designed for hair that’s been pushed to the limit—through bleaching, chemical treatments, or frequent heat styling—it rebuilds hair from the inside out, reinforcing the structure and restoring vitality.

What It Does:

• Reconstructs Hair Fiber: Repairs deep structural damage caused by overprocessing and external stressors.

• Strengthens from Within: Boosts elasticity and resistance to breakage with concentrated proteins.

• Restores Resilience: Reinforces weakened strands and reduces split ends and snapping.

• Revives Severely Compromised Hair: Helps hair regain softness, density, and manageability.

Perfect For:

• Hair that is frequently bleached or chemically treated

• Fragile, thinning, or easily breaking strands

• Hair damaged by daily heat styling (straighteners, curlers, etc.)

• Over-processed hair lacking structure or bounce

Key Ingredients:

• Protein Complex: Delivers targeted protein reinforcement to repair weakened keratin chains, improving tensile strength.

• Ceramides: Fill gaps in the cuticle, restoring smoothness and protecting the hair from future damage.

How to Use:

1. Step 1: Mix the Treatment
   Blend one dose of Concentré Resistance with one dose of Booster Reconstruction in a bowl until fully mixed.

2. Step 2: Apply to Damp Hair
   On freshly washed, towel-dried hair, apply the treatment evenly from mid-lengths to ends, concentrating on damaged areas.

3. Step 3: Let It Work
   Leave on for 5 minutes to allow the protein complex to penetrate and reconstruct.

4. Step 4: Rinse Thoroughly
   Rinse well with warm water. Follow with your preferred styling products.

Pro Tip: Use weekly or bi-weekly depending on the level of damage. Ideal post-bleach or after intense styling periods.
