THE PHYSICS OF FRICTIONLESS SLEEP
Silk's unique protein structure - sericin and fibroin - creates a surface with a coefficient of friction dramatically lower than cotton.
Independent lab testing confirms silk reduces hair friction by 34%, meaning each strand glides rather than catches and tears.
Souleir's 6A-Grade 22 Momme silk goes further. The thread count weave creates a surface so dense and smooth that individual fibres have minimal contact points with each hair shaft - the highest standard available in the Australian market.
