BRILLIANT BROWS FOR HOLLY

CELEBRITY eyebrow gurus have been using maths to create the perfect arch for years. Brow shape is determined by the golden ratio, an ancient formula that is equivalent to the Greek letter Phi — or 1.6 today. two quantities are said to be in the golden ratio if their ratio (a : b) is the same as the ratio of their sum to the larger quantity (a+b: a). On a ‘perfect’ face, the high point of the eyebrow should divide the arch at the golden ratio point of the eyebrow. By this measure, TV presenter Holly Willoughby has perfectly arched eyebrows.
