Repair From the Inside Out. Real Recovery for Damaged Hair.

Damaged hair isn't just a surface problem — the harm happens deep inside the strand, where chemical processes, heat, and mechanical stress break the bonds that give hair its strength and elasticity. Real repair means rebuilding from the inside: reconnecting broken disulfide bonds, replacing lost protein, and restoring the cuticle's ability to protect the cortex. Our damaged hair collection is built around this science — featuring bond builders, protein reconstructors, and cuticle-sealing treatments used by professional colorists and stylists across North America.

Foire aux questions

Can damaged hair actually be repaired?
Partially. Once split ends form, trimming is the only true fix. But bond-building treatments (like Olaplex) can reconnect broken internal bonds and significantly improve strength, feel, and appearance — making the damage far less visible.
What's the difference between a protein treatment and a deep conditioner?
Protein treatments rebuild the hair's structural framework (great after chemical damage). Deep conditioners add moisture and softness. Damaged hair usually needs both — alternate weekly to balance strength with hydration.
How does Olaplex work?
Olaplex contains bis-aminopropyl diglycol dimaleate, which reconnects broken disulfide bonds in the hair's cortex. Unlike conditioning agents, it repairs structure — not just coating it. Used regularly, it progressively rebuilds hair integrity.
How long does it take to see results from repair treatments?
Most people notice softness and reduced breakage within 2–4 weeks of consistent use. Full structural recovery depends on how damaged the hair is — severe bleach damage may take 3–6 months of regular treatments.
Should I cut damaged hair or try to repair it?
Both. Bond builders and protein treatments dramatically improve strength and appearance, but true split ends can't be fused permanently — a small trim removes the worst ends while treatments protect the rest.
Can I use bond builders on coloured hair?
Yes — bond builders are colour-safe and actually help colour last longer by keeping the cuticle sealed. Many colourists use Olaplex during the colour service itself.
How do I prevent damage from coming back?
Space out chemical services, always use a heat protectant, keep hot tools under 185°C, and alternate protein with moisture. Weekly maintenance with No.3 or K-PAK keeps rebuilt bonds strong.
