Unlike most volumising products on the market, the new Colour Wow Xtra Large Bombshell Volumizer (£23) doesn't contain the salts or dry resins that can leave hair feeling dry, tangled, and brittle. Instead, the innovative formula — which comes out of the pump a frothy foam and transforms into a nonsticky liquid when you rub it in between your palms — contains flexible bamboo polymers that add fullness to your hair whilst still leaving it touchable and soft. "I love Xtra Large because it gives the hair amazing memory and hold, but also a really luxurious finish," hairstylist Dom Seeley told POPSUGAR, adding that you can still run your fingers through your hair with it in (and as someone who uses a lot of volumising sprays and mousses, I can tell you that's usually not the case). I tried the product and was shocked with the results — it looks like I had double the amount of hair, as if someone had added extensions throughout.
