What Is PLX PRO? Science-Backed Bond Repair Explained  

Every strand of hair is held together by millions of disulfide bonds — the chemical cross-links that give hair its strength and elasticity. Chemical services (colouring, bleaching, perming) work by breaking these bonds. Without protection, repeated chemical services progressively destroy more bonds than they repair, leaving hair increasingly brittle and prone to breakage.

PLX PRO is Dorofey's two-step bond repair and protein hair treatment system that works at the molecular level — protecting existing bonds during the chemical process and actively rebuilding broken bonds afterward. Unlike protein masks or conditioning treatments that work on the surface, PLX PRO's active chemistry penetrates the cortex to work on the structural bonds themselves.

PLX PRO Products: The 2-Step System

PLX PRO Bond Multiplier No.1 (250ml): Mixed directly into colour or bleach before application. Works in real time during chemical processing — binding to disulfide bonds and shielding them from the chemical reaction without affecting the colouring or bleaching result.

PLX PRO Accomplisher No.2 (250ml): Applied after the chemical service is rinsed out. Actively cross-links broken bonds — re-welding the structural connections disrupted during processing. Simultaneously seals the cuticle, locks in repair, and leaves hair visibly stronger, shinier, and measurably more elastic.

When to Use PLX PRO: Complete Protocol for Stylists

During colour/bleach service: Mix No.1 into colour or bleach at 1:1 ratio before application. No change to processing time or technique required.

After rinsing: Apply No.2 to towel-dried hair. Leave 10 minutes. Rinse. Continue with finishing process. The 10-minute step delivers the bond reconstruction that protects long-term hair health.

For clients undergoing frequent colouring or bleaching, the PLX PRO protocol should be standard at every appointment — the cumulative protective effect across multiple services is where the greatest long-term benefit is seen.
