Frizz, often misinterpreted as mere lack of moisture, is fundamentally a structural issue concerning the hair’s outermost layer. Specifically, it involves the lifting of cuticle scales — a condition known as hydrophobicity.
When hair is healthy, its cuticle scales lie flat, overlapping like roof tiles. This smooth surface reflects light, creating shine, and acts as a barrier against environmental stressors.
Hair fibres absorb atmospheric moisture, causing them to swell. If the cuticle is compromised — perhaps by chemical treatments or heat — these scales do not swell uniformly and lift, resulting in a rough, uneven texture.
Highly porous hair, often due to damage, has gaps and irregularities in its cuticle. These imperfections allow water to penetrate and exit rapidly, leading to the characteristic frizz as the hair attempts to equalise its internal moisture with the surrounding humidity.
The hair’s natural pH, typically between 4.5 and 5.5, is crucial for maintaining cuticle integrity. Products with an alkaline pH can cause the cuticle to swell and open, exacerbating frizz.
Most conventional haircare approaches address frizz by simply adding heavy occlusives. Evera, however, focuses on biomimetic ingredients that help to reseal and smooth the cuticle, promoting a balanced moisture exchange.
Ingredients such as specific polysaccharides and ceramides are vital. These compounds work to reinforce the hair’s natural lipid barrier, preventing excessive water uptake and promoting cuticle alignment.
The application of gentle, acidic rinses or products formulated with a balanced pH helps to tighten the cuticle. This action reduces its propensity to lift, thereby mitigating frizz.
It is not about saturating the hair with moisture, but rather about managing how moisture interacts with the hair shaft. A well-sealed cuticle prevents unwanted swelling and subsequent roughness.
Understanding frizz as a cuticle-related structural imbalance, rather than mere dryness, allows for a more targeted and effective approach to hair health.
