We all know an onion can make a dull recipe shine a little brighter with its strong and distinct flavor. Apparently, the bulbs can have a similar effect on our hair, too.
It might sound a little crazy, but people have been using onion juice for hair growth for years! There have even been scientific studies on the veggie’s revitalizing abilities. Researchers claimed in 2002 that “use of crude onion juice” helped significantly improve participants hair re-growth. It also only took two weeks of applying it to their scalps to see the results. It was an admittedly small study, but it still sounds pretty promising.
So, what is it about onions that make them helpful for follicle frustrations? Another study from 2012 explained that it has to do with the sulphur content: “Sulphur is a mineral present in every cell in our body, with its greatest concentration in hair, skin and nails. It has often been called the ‘beauty mineral’ and the ‘healing mineral’ because of its ability to promote circulation and decrease inflammation.”
That said, we obviously understand that the idea of soaking your head in pungent onion juice probably doesn’t sound all that appealing… But it’s also definitely cheaper than trying pricey medical treatments or products.
There are many different ways to use onion juice for hair growth that people have written about or just passed around to friends in conversation over the years. MedicalNewsToday recommends simply peeling, chopping, and squeezing the pieces with your hands (or using a juicer) to get the juice out. You can also use your blender to create more of a paste instead. Either way, you can add essential oils, like peppermint or lavender, to help tone down the smell before applying it to your scalp for about 15 to 30 minutes. Be careful not to let any of it drip into or around your eyes and then just wash normally to get rid of any lingering aroma.
Here’s hoping any odor is worth it when you notice fresh sprouting strands start to pop up!
