​PhiBrows Microblading is a manual, semi-permanent technique of hyper-realistic eyebrow drawing in which the shape of eyebrows is calculated according to facial morphology and golden proportion (phi 1,618). The technique is intended for anyone over the age of 18 who wants to correct the aesthetic problems of their eyebrows. People suffering from hair loss through over plucking, ageing, alopecia or trichotillomania benefit greatly from PhiBrows.
