The hair fibres are electro statically charged, creating a magnetic effect, binding them to existing hair cells, thus maximising their holding potential. They produce dramatic density with volume and totally undetectable coverage to your thinning and balding areas. Each fibre hold spray increases the bond between Volumon Professional Hair Building Fibres and thinning hair to give you optimum results meaning a thicker and fullness head of hair. Made easier with the optimiser comb to help spread the fibres evenly.
