Try as we might to retain the shiny locks that come with dedicated GHD time every morning, the slightest suggestion of summer humidity is enough to wave goodbye to sleek sophistication, and hello to Monica Geller hair.
Those days might be over, thanks to Color Wow's that shoppers are hailing as a 'miracle product' for shielding their hair from the summer heat.
Inspired by new textile technology, the heat-activated spray cloaks each hair strand with an invisible polymer, which then compresses, tightens and seals the hair to create a foolproof 'humidity guard'.
It couldn't be simpler to user either, as you simply spritz damp hair before you blow dry, leaving hair 'supernaturally-sleek, smooth and super-silky'.
According to keen beauty lovers, who have left hundreds of 5-star reviews for the £24 spray on Amazon, it's got serious staying power, too.
"The effect is soft, shiny hair with glass-like reflections," one happy customer wrote. "Not only that, but when a hot flush hits and I find myself with damp hair, once it dries out again, it simply falls back into place. No frizz or curls whatsoever."
"This product is incredible. I have thick coarse hair and my hair looks as great on day 6 as it did on day one," another added.
"I live in the South. Here, Alabama football reigns supreme and the only thing higher than an Alabama football score is the humidity. It is relentless and unforgiving. I can have a beautiful blowout, walk outside, and see all of my work frizz out within a matter of minutes. In short, this product is AMAZING!," a third shopper enthused.
The best part? Your newfound glass hair will last up to 2 to 3 shampoos, saving you much-needed hair-washing time to spend on your new Netflix obsession. If that's not smart beauty, we don't know what is.
