Mevys Professional Sulfate-Free Nourishing Conditioner Color Safe Treatment

Yes. Its acidic pH (4–5) supports cuticle compactness, which helps maintain color longevity and surface smoothness after chemical services.

• Why Acidic pH Matters for Conditioner and Color Safety?

Hair naturally has a slightly acidic surface pH (approximately 4.5–5.5). During cleansing — and especially during chemical services like coloring or bleaching — the cuticle layers of the hair lift, and the internal structure becomes more vulnerable. An acidic conditioner (pH 4–5) is essential because it helps re-compact the cuticle layers after washing, restoring surface alignment and reducing porosity. When the cuticle is more compact, light reflects more evenly (improving shine) and artificial pigments remain better sealed within the fiber. This is particularly important for color-treated hair, as an alkaline or improperly balanced product can prolong cuticle swelling, increasing pigment loss and fading. By maintaining an acidic pH, the Mevys Conditioner supports cuticle stability, enhances color longevity, and helps return the hair to a balanced, controlled state after cleansing or chemical exposure.

The Mevys Conditioner is built primarily on a cationic conditioning system. These ingredients:

• Bind selectively to negatively charged areas of the hair

• Improve slip and reduce friction

• Form a controlled, thin conditioning film

The conditioning system is balanced and lightweight. Because the formula does not rely heavily on dense oils or high levels of heavy silicones, the film deposited on the hair surface is relatively lightweight and uniform, delivering softness without collapse, improved movement ,reduced static, controlled surface lubrication

• Note: Lightweight conditioning agents can create perceived heaviness on fine hair if over-applied — not because the formula is heavy, but because fine fibers have smaller diameter and lower structural mass, thus fine hair types should apply primarily from mid-lengths to ends to avoid excess weight.

No. When properly formulated and used in rinse-off conditioners, cetrimonium chloride, cetyl and cetearyl alcohol do not damage the hair. In fact, they are conditioning agents designed to improve fiber behavior.

• What is the scientific approach towards these ingredients?

Cetrimonium Chloride is a cationic (positively charged) conditioning agent that Binds selectively to negatively charged areas (a byproduct of shampooing), reduces static electricity, improves wet compability, decreases friction between strands and helps align the cuticle surface. Its function is surface lubrication and manageability, not chemical alteration of the hair structure.

Cetyl & Cetearyl Alcohol are fatty alcohols and despite misconception, these are not drying alcohols. Fatty alcohols are waxy and emollient, help thicken and stabilize the conditioner, improves softness and slip while supporting a smooth, creamy texture. In conditioners, fatty alcohols actually improve conditioning performance and fiber smoothness.

Contrary to popular belief, these components are implemented to protect manageability — not compromise it.

Yes. It is specifically formulated for chemically treated and heat-stressed hair. Hydrolyzed keratin and silk amino acids provide targeted cortex support, while conditioning polymers protect the cuticle—helping hair feel stronger, smoother, and more resilient over time.

Mevys Leave-In Reconstructor contains fatty alcohols which behave very differently from drying alcohols that evaporate quickly and can leave hair feeling brittle. Fatty alcohols help:

• Smooth the hair surface
• Improve softness and slip
• Support moisture balance
• Make the product easier to spread evenly

This leave-in uses an alcohol that helps hair feel softer and healthier—not one that dries it out.

It is a leave-in treatment, not a traditional rinse-out conditioner. While it delivers instant softness and detangling, it also provides ongoing protection and targeted cortex support through hydrolyzed proteins and amino acids that help strengthen the hair from within while sealing and protecting the cuticle.
