A silicone shine serum that gives coloured hair a glossy, smooth finish
L'Oréal Professionnel Serie Expert Vitamino Color Spectrum Glass Shine Serum is a leave-in hair serum for coloured hair that looks dull or frizzy. Its silicone-based formula coats the lengths with a thin, even film that reflects light, so colour looks brighter and hair feels smoother. It helps keep frizz down in humid weather and protects the lengths from the heat of the dryer and styling tools. A few drops are enough on fine hair, a little more on thick or long hair.
The texture
A clear, fluid serum with a silky, slightly slippery feel. It spreads easily between the palms and through the lengths without making hair sticky, as long as you keep to a small amount. It has a fresh salon scent.
Who it suits
- Coloured, highlighted or bleached hair that has lost its shine
- Frizz-prone hair in humid weather
- Anyone who blow-dries or uses straighteners and wants a smoother finish
- Medium to thick lengths that need polish without a heavy cream
Worth knowing before you buy: This is a silicone serum with fragrance and no water, so it sits on the surface of the hair rather than caring for the scalp. Too much can weigh fine hair down: start with one or two drops and keep it off the roots. For care that works on colour fade in the shower, pair it with the Vitamino Color shampoo and mask.
How long one bottle lasts
Used at 2 to 3 drops per application, 3 or 4 times a week, the 50ml bottle lasts around three to four months. Very long or thick hair will get through it faster.
