Want holographic and glitter hair? We tested the IGK Foamo Holographic Hair Foam in our beauty lab! IGK's Foamo Holographic Hair Foam is described by the brand as "a glitter-infused foam that’s enriched with blue sea kelp and moonstone extract in order to create cosmic colour the moment locks are exposed to the light." It comes in two shades, Moonrock, and Metero. Each bottle costs £19 and claims to give hair a temporary 'cosmic shimmer'. Intrigued? See what we thought...
