Kerastase Resistance Serum Therapiste Dual Treatment Fiber Quality Renewal Care (Extremely Damaged Lengths and Ends) 30ml/1.01oz

Reveal remarkably resilient lengths and ends with Kerastase Resistance Serum Therapiste Dual Treatment. This advanced dual-action formula blends an oil and a cream texture to repair, fortify, and renew hair that’s extremely damaged, giving you a healthier, more polished look from roots to tips.

• Dual-action texture for deeper repair The lightweight oil nourishes the surface and seals the cuticle, while the creamy phase penetrates to rebuild strength from within for a comprehensive repair that ordinary serums can’t match.
• Targets extremely damaged lengths and ends Specifically formulated to revitalize fragile portions of the hair, restoring fiber integrity where damage is most visible and most at risk of breakage.
• Fortifies and improves elasticity By reinforcing the hair fiber, it enhances manageability, making lengths feel more resilient and less prone to snap during styling or brushing.
• Enhanced heat protection Provides better protection during heat-styling sessions, helping to minimize further damage from tools like straighteners and curling irons.
• Visible reduction of split ends Continuous use helps reduce the appearance of split ends, delivering a smoother, healthier-looking finish over time.

Who should consider it? Ideal for anyone with severely damaged hair due to chemical processing, frequent heat styling, or environmental stress. If your lengths and ends feel brittle, look dull, or lack the elasticity you remember, Serum Therapiste Dual Treatment is designed to restore structure and radiance from the inside out.

How to use for best results

1. Apply to towel-dried lengths and ends, avoiding the scalp to prevent buildup.
2. Dispense 1–2 pumps (adjust for hair length) and warm the product between your palms before distributing evenly with your fingers or a wide-tooth comb.
3. Leave-in as a part of your routine; you can also use a small amount on dry hair to smooth flyaways and add a final touch of polish after styling.

Size: 30 ml / 1.01 oz — a travel-friendly, performance-driven addition to the Kerastase Resistance line. With continued use, hair appears sleeker, nourished, and healthier over time, with strengthened fiber that stands up better to daily styling and environmental stresses.
