BioKeratin Beauty is an advanced blend of nutrients specifically designed to boost and maintain healthy keratin levels in the hair, skin and nails. BioKeratin is also formulated to protect our hair, skin and nails from free radical damage, which can make them dull, dry and brittle. Keratin is essentially the structural component of hair, skin and nails, which can naturally be produced in our bodies and we can boost keratin repair from certain foods but as we age our bodies become less effective at extracting and producing keratin.
