Nathan Walker from Trevor Sorbie for L’Oreal Professionnel says dark hair can start to look dull as the seasons change: “In much of the UK, the summer sees the sun rise to a peak of around 60 degrees; that’s four-times higher than in the mid-winter,” he explains. “So how does this affect hair? The simple answer is there is less light reflected so hair appears duller. Other major factors are the dehydrating effects the summer has had coupled with us all starting our central heating up and further dehydrating the hair. The environmental effects from the summer also influence the surface of the hair, often roughening the cuticle layer and again leads to less light reflecting, so causing a dull look and feel.”
But brunette clients are in for a treat this autumn with a multitude of products available to transform it from lacklustre to luscious. “We all know high shine products, whether it’s nail polish or a skincare product, changes seasonally and hair needs this too. I’d prescribe an initial in-salon treatment with Metal Detox from L’Oreal Professionnel, this will remove any metallic deposits from the summer that could be making the hair look dull, then over this a shine intensifying acidic colour such as L’Oreal Professionnel Dia Light which can be just clear or can replace some of the depth lost over the summer.”
