If you're after salon-worthy shine in a few minutes, Amika Flash Instant Shine Mask (£21) is your answer. It does exactly as it promises, "delivers brilliant moisture and shine in just 60 seconds." The key is the amino acids in the formula, which smooths your hair from roots to ends and boosts hair elasticity, meaning it's less prone to breakage.
Thanks to its lightweight formula, the Amika Flash Instant Shine Mask is great for most hair types. Amika recommends fine and oilier hair types using the treatment in place of conditioner, and thick, coarser hair types using it after a conditioner on mid lengths and ends. The quick application also means it's supereasy to incorporate into an existing hair routine. The shine treatment also smells amazing, which in a hair product, is always welcome.
