Strengthening & Fortifying Hair Products
393 produitsRebuild Broken Bonds — Stronger Hair from the Inside Out
Strengthening and fortifying products work in two distinct ways. Protein treatments (like keratin, hydrolyzed wheat protein, and rice protein) coat or penetrate the hair shaft to temporarily fill gaps in the cuticle, adding structure and reducing breakage. Bond-repair technology — pioneered by Olaplex's bis-aminopropyl diglycol dimaleate and now advanced by K18's biomimetic peptide — actually reconnects broken disulfide and polypeptide chains within the cortex, restoring the hair's original strength from within rather than just masking damage.
ProHair.ca carries the most complete selection of strengthening hair care, including Olaplex, K18, Joico K-PAK, Redken Extreme, Schwarzkopf Bonacure Fibre Force, and more. Whether your hair needs emergency bond repair or steady daily fortification, we have the right system — in salon sizes and retail — sourced from authorized distributors.

Bond Repair Treatments
Scientifically advanced formulas (Olaplex, K18) that reconnect broken disulfide and polypeptide bonds deep inside the cortex. The most powerful repair available without a salon visit.
Protein Treatments
Hydrolyzed keratin, silk, and wheat protein formulas that fill cuticle gaps and add temporary structural support. Best for hair that is limp, overly elastic, or prone to breakage.

Rinse-out conditioners with structural proteins and ceramides that add slip and strength simultaneously — reducing breakage during detangling and brushing.
Leave-In Strengtheners
Heat-activated or ambient-working leave-in treatments (like K18) that continue to repair bonds after application, every time you style or wash.
Deep Repair Masks
Intensive weekly treatments with concentrated protein and bond-building actives. Used 1–2 times per week on damaged or chemically processed hair.
