Hair Filler Strength Repair Serum, €15.16, Garnier Fructis

It’s a surprisingly inexpensive and cheerful hair update for Clooney – a woman with a closet full of designer dresses and multiple homes – even if it was expertly done by a world-leading colorist.

It seems Amal’s caramel highlights are on trend. “We see a lot of brunettes going lighter in the autumn and wanting that ‘salted caramel’ look,” says lead colourist Anita Rice of Buller and Rice salons in London. (I’ve been going to Rice for five years now and get my own version of a very lightly lightened brunette, although not quite caramel.)

So are salted caramel and toffee highlights the latest way to spice up brunette hair? Hairdresser and trend forecaster Tom Smith thinks so. “Amal has gone for a very bold statement, but it’s not a complete reinvention of her look, which makes it really effective,” he says. “Her hair has gone as light as possible, but still looks like a true brunette.”

Face-framing “bronde” look

Amal’s colorist achieved this lightened effect by placing lighter “bronde” sections — a warm honey blonde in hairdressing parlance — around the face. The further away from the face the color goes, the deeper and more “natural” brunette it becomes. “It’s a trick we use as colorists to make a person’s hair appear lighter without losing their identity as a brunette,” adds Smith, who cites Kamala Harris and Jennifer Lopez as other examples of women who have used this strategy.
