The Professional Protocol
Hair is a complex biological structure whose structural integrity depends on keratin, the fibrous protein that provides strength, elasticity, and density.
Performing technical services in a salon or at home—whether coloring, bleaching, or styling treatments (perms)—triggers chemical processes that, if not handled professionally, can compromise this fundamental structure.
The Impact of Chemical Treatments on the Hair Fiber
During chemical treatments, alkaline agents and oxidizers penetrate the cortex to alter pigments (color) or to break and reorganize keratin bridges, specifically disulfide bonds (shape).
This chemical stress alters the fiber’s pH and porosity. If not counteracted, the result is progressive weakening that leads to brittle, dull hair and an inevitable increase in the risk of breakage. Protecting keratin is therefore not an option, but a necessity to promote the hair’s well-being.
Protection Strategy: A Synergistic Protocol
To preserve the integrity of the hair fiber, it is essential to adopt a professional reconstruction protocol that works synergistically before, during, and after the technical service. Napura’s The Builder line is designed to meet this need with a methodical five-step system featuring four products:
-
Step 1: Keratin Mix, a keratin-protective serum provides highly effective protection against the oxidation that affects the hair’s keratin during color-related technical services.
-
Step 2: Keratin Fit, serum-removing shampoo, a specialized shampoo for washing hair during coloring or bleaching.
-
Step 3: Keratin Fix, a repairing serum for hair stressed by coloring and/or bleaching treatments, which restores and strengthens the hair’s keratin structure.
-
Step 4: Keratin Fit, serum-removing cleanser.
- Step 5: Keratin Flex, a hair-beautifying spray and the final step of The Builder Treatment, which restores the pH balance while sealing the hair cuticle.
From Damage to Regeneration
Understanding the chemistry of the hair fiber is the foundation of an expert colorist’s technical service. Adopting a targeted protocol like The Builder is not just protection, but a guarantee of results.
It allows you to perform advanced technical services while preserving healthy, strong, and lustrous hair, transforming the chemical treatment from a potential source of stress into a true ritual of structural regeneration.
