The science behind most.
Why human keratin
changes everything.
Most fiber brands use synthetic keratin. most. uses human-grade keratin — the same protein your hair is made of. That’s why it looks real. Because it is.
Natural keratin that bonds to hair like it belongs there — because it does.
60–80 micron diameter
Human hair is 60–80 microns wide. most. fibers are engineered to the exact same diameter — so they blend, not clump.
Matches real hair exactlyElectrostatic bonding
A natural electrostatic charge bonds fibers to your existing hair strands — not your scalp. They move with your hair, not against it.
Stays in place for 12+ hoursNo ammonium chloride
Most competitors use ammonium chloride as a binding agent. most. doesn't. No scalp irritation, no residue, no long-term damage.
Clean formulaTested at 80km/h wind
Independent lab tests confirm most. fibers hold at 80km/h wind speed. Sweat and humidity resistant. Washes out with shampoo.

Bonding agentIron Oxides
Cosmetic-grade iron oxides create the 12 natural shades. The same pigments used in premium makeup — safe, stable, fade-resistant.
Colour pigmentsWhat we left out
