This Shampoo Has 9000 Positive Reviews on Amazon—and We've Never Heard of It

Amazon never ceases to amaze us with its under-the-radar beauty gems, and often, these products already have thousands of devout followers by the time we're alerted to their existence. Case in point: When the online marketplace shared news of its top-selling products back in 2016, we were just as surprised as anyone to see the number two slot go to a shampoo we'd never heard of. But nearly 9000 positive reviews can't steer us wrong, right?

The product in question is Pura d'Or Anti-Hair Loss Premium Organic Argan Oil Shampoo (£43). Thanks to a hefty dose of ultra-hydrating argan oil, this shampoo isn't only effective for thickening fine strands, but it can also moisturise, fortify and add shine and body to just about any hair type. All that and it's free of preservatives and harmful chemicals. (It's also gluten-free, need we say more?)
