As someone willing to do whatever it takes to grow longer, healthier strands, I’ve been spending a lot of time on #HairTok, where the latest obsession is onion shampoo. While most people are searching for shampoos with onion as the hero ingredient to promote hair growth, some TikTok users are taking it a step further by blending onions into a DIY oil and applying it directly to their scalps. According to Spate, interest in onion shampoo is up 106.8% on Google search, with TikTok content around the trend pulling in an average of 3.1 million weekly views. While I was initially surprised, I’m no stranger to at-home remedies. Growing up, my mom would whip up hair concoctions with eggs or blended papaya, all in the name of stronger, shinier hair. But onions? Those were never in our lineup. But as it turns out, onions in hair care have been around for a while, with roots in Ayurvedic tradition.
Before you start chopping away in your kitchen (and inevitably crying off your mascara), I had to ask the experts: Is there any scientific evidence behind using onions for hair growth? Is it safe to use onions directly on the scalp? And is this really the best option when it comes to boosting overall hair health? Read all about it below, plus a few onion-infused products worth trying, per the experts.
