Others asked for more details about her routine, wondering if the color of the onion mattered, and some even shared their own experiences with the hack.
“I have to try boiling the onions .. I was juicing them and left it too long .. & for an entire year, anytime my hair was blowed out or straightened it smelled like Sofrito 🥴🤦🏾♀️,” @iamjuju_ commented.
But what is it about onions that has steered us from donning goggles just to be in the same room as them to pouring their essence onto our heads?
According to Healthline, onions actually have anti-inflammatory and antimicrobial properties, which researchers have suggested can help your hair grow and enhance its health. They also point to potential benefits for those with alopecia or dry, itchy scalps, and explain how to produce your own onion extract and add it to your pre-existing hair products. According to Martha Stewart, those benefits largely stem from an onion’s high sulfur content.
While there doesn’t appear to be much research on using water that onions have been boiled in, it seems as though it may be a good alternative for those with sensitive skin, which can be triggered by pure onion juice.
