Overview
Realigning hair that actually lasts begins where most protocols end: inside the fibre. This guide shows how to repair, realign and seal in a single professional protocol — designed for damaged, coloured, textured and high-density hair — without sacrificing movement, shine or integrity.
The everyday struggle of realignment that doesn’t last
Every stylist has seen it. The finish looks immaculate in the chair — sleek, reflective, disciplined. Days later, frizz creeps back, the surface turns dull, and the fibre feels rough or rigid.
Common symptoms you’ll recognise:
- Frizz and puffiness returning after a few washes.
- Weak, porous fibres that break under tension.
- Uneven alignment across sections; “rebound” effect.
- Heat that seems to dull instead of polish.
- Clients saying, “It only lasted a week.”
These aren’t isolated issues; they point to the same root cause.
The real cause: bond disorganisation & heat fatigue
Most smoothing systems coat the cuticle but leave the cortex fragile. With each colour service or thermal pass, internal bonds (hydrogen, ionic, disulphide) become disorganised. Elasticity drops, the cuticle lifts, and the surface loses coherence.
When structure fails, shine and smoothness fade — no matter how advanced your technique.
Without bond reconstruction, alignment is cosmetic and short-lived.
Understanding fibre structure (quick science)
- Cuticle: the outer shield; when sealed and orderly, it reflects light.
- Cortex: the elastic core; where strength, memory and flexibility live.
- Internal bonds: the “architecture” connecting keratin chains.
Heat, alkalinity and mechanical stress can weaken this architecture. A protocol that stabilises bonds while aligning preserves the cortex and sustains results.
Common mistakes in thermal realignment (and how to avoid them)
- Overheating (>220°C): lipid burnout; cortex fatigue; brittle gloss.
- Insufficient cleansing: residues block penetration; patchy performance.
- Excessive passes: friction lifts cuticle; roughness returns fast.
- Poor tension control: inconsistent slip → uneven alignment.
Professional fix: Adopt a fibre-first, bond-support protocol so each pass is safer and more efficient.
Repair • Realign • Seal — the protocol that changes everything
WHY — performance without compromise
Salons need predictable, repeatable results across real-world hair: damaged, coloured, textured, dense. That demands structure first, finish second.
HOW — B-Plex™ System
B-Plex™ is a biofunctional complex that rebuilds internal bonds during thermal alignment. A synergy of biomimetic amino acids, biosilicon and bio-lipids boosts elasticity, cohesion and cuticle order — as you align.
Technical benefits (at a glance):
- Reinforces internal structure under heat.
- Improves elasticity; reduces mechanical stress.
- Smooths cuticle for a reflective, flexible finish.
- Delivers discipline without stiffness.
WHAT — the 3-step professional flow
- Rebonding Shampoo — technical cleanse to equalise the surface and improve absorption.
- Keraplex Treatment — realigns and rebuilds in one step with B-Plex™ support.
- Mask Therapy (optional finisher) — NanoShield™ regeneration and sealing for softness and shine.
Primary outcomes: uniform alignment, controlled volume, natural movement, lasting gloss, and fibre integrity that holds up to real life.
Temperature & Passes — personalisation that protects
Use this as a practical matrix. Always adjust for porosity, chemical history and live fibre feedback.
- Coloured or sensitised: 190 °C | 10-15 light passes | gentle tension; consistent rhythm.
- Textured or afro: 220 °C | 10-15 passes | fine sections; steady movement.
- Thick / high-density: 200 °C | 10-15 firm passes | controlled pace; moderate pressure.

From surface to core — why B-Plex™ differs
Surface polymers alone can look neat for a week — then crack under daily stress. B-Plex™ targets the cortex, where elasticity begins.
- Biomimetic amino acids: mimic keratin peptides; support bond re-formation.
- Biosilicon & bio-lipids: help retain moisture and buffer heat stress; improve slip and reflective finish.
This dual action — rebuild inside / align outside — is what transforms results from “temporary” to repeatable and durable.
Combining systems: finish & maintain
Where professional care meets lasting performance.
The secret to long-lasting alignment doesn’t end at the salon — it’s in the finish and aftercare.
That’s why every Rebonding ritual is designed to connect seamlessly with Piur’s complementary systems: Mask Therapy and Home Care Maintenance.
Finish with Mask Therapy — Deep Regeneration & Protection
After realignment, the fibre needs to stabilise — to rebuild its internal bonds and lock in hydration.
Mask Therapy, powered by NanoShield Complex™, delivers deep regeneration and long-term protection through a blend of bio-lipids, amino acids and antioxidants.
💧 Benefits:
- Repairs internal structure post-alignment
- Restores elasticity and smoothness
- Seals the cuticle for luminous reflection
- Forms a lightweight protective barrier
Result: Softer, stronger, and visibly regenerated hair — ready for daily styling.
Use: Apply after rinsing Keraplex; leave for 8–12 minutes and rinse thoroughly.
Maintain with Piur Home Care — Prolonged Discipline & Radiance
Salon results deserve continuity. The Piur Care System was formulated to preserve alignment, hydration and softness between services — using vegan, sulphate-free and biofunctional formulas derived from the same professional technology.
🧴 Benefits:
- Extends the longevity of professional smoothing results
- Maintains the hair’s natural movement and shine
- Provides deep nourishment without heaviness
- Protects colour and fibre integrity between appointments

How many passes for thick or textured hair?
Typically 8–10 controlled passes at 195–205 °C. Adjust by porosity and density.
Is it suitable for afro hair?
Absolutely. Engineered for elasticity + discipline on textured fibres.
How long do results last?
Up to ~12 weeks, depending on maintenance and wash frequency.
What’s the ideal maintenance routine?
Use Piur Home Care between services; it protects the finish and extends the smoothing effect.

Performance that clients can feel (and trust)
True professional performance is not “stick-straight at any cost”. It’s structure with movement, discipline with softness, and results that hold.
With Rebonding | Keraplex, you rebuild, realign and seal in one intelligent system — engineered for the realities of damaged, coloured, textured and dense hair.
