A single hair strand can absorb up to 30% of its weight in water vapour. This property explains why frizz often appears even on hair that feels well-hydrated; it is primarily a response to atmospheric humidity.
When the air is moist, water molecules attempt to enter the hair shaft. If the hair’s outermost layer — the cuticle — is compromised or raised, these molecules penetrate unevenly, causing the internal structure to swell.
This uneven swelling leads to the characteristic unruly texture we perceive as frizz. It’s a phenomenon of expansion and disruption, where individual strands no longer lie smoothly.
Hair porosity — its ability to absorb and retain moisture — dictates susceptibility. Highly porous hair, often due to chemical treatments or heat damage, has a more open cuticle, making it particularly prone to absorbing excess humidity.
Effective frizz management therefore extends beyond simply applying oils. It necessitates strengthening the cuticle and creating a smooth, hydrophobic barrier that prevents water ingress.
Most conventional products rely on heavy silicones to coat the hair, offering a temporary fix that can build up over time without addressing underlying structural integrity.
Evera’s approach prioritises botanical solutions that form a natural, breathable film. We select specific polysaccharides and glycerides that work to gently flatten and seal the cuticle, maintaining a balanced pH.
This method regulates the hair’s interaction with ambient moisture, offering sustained protection without a heavy feel. The aim is to reinforce the hair’s natural defence.
Our formulations utilise ingredients that create a lamellar structure around each strand, mimicking hair’s natural lipid layers. This helps to reduce swelling and maintain smoothness.
Understanding frizz as a structural response to humidity — not just a sign of dehydration — allows for a more precise and effective regimen.
