It’s no wonder to see the onion shampoo on the shelves of supermarkets or specialty shops. Some studies point out that this plant has properties that would be very beneficial for hair care, such as excessive fall, dryness, or easy breakage.
While it may be surprising, the onion has shown some interesting properties for hair health. The answer is in its content: vitamins, flavonoids, or minerals.
When added to the hair, onion juice can provide extra sulfur to keep a strong, thick hair, thus preventing hair loss and promoting its growth. For this reason, shampoos have proliferated based on this ingredient.
There are several studies that have pointed to their possible benefits. Thus, for example, an article published in the Journal of Dermatology obtained certain results that confirm that the onion could serve to stop hair loss, and therefore that it would be an appropriate ingredient in treatments against alopecia.
Healthy hair growth
Other studies by researchers at the Adarsh College of Pharmacy Vita in India found that onion helps promote healthy hair growth. This is because their extracts, combined with coconut, eucalyptus, or castor, manage to stimulate hair growth, nourish hair follicles, and moisturize the hair and scalp.
Similarly, other research shows that the onion properties also help to curb dandruff, thanks to its antifungal and antimicrobial properties.
However, the results obtained in these studies are not definitive, and it should not be forgotten that the hair changes are complex and depend on many factors: state of health, nutrition, or medication. Therefore, as with any other product, we have to bear in mind that miracles do not exist.
Onion as a natural remedy
On the other hand, certain aspects should be considered when using onions in hair treatments. Especially when we use it as a natural remedy. First, anyone allergic to onions shouldn’t put onion juice in their hair. Another problem may be the smell. In this case, we can add a little lemon juice or rose water.
Finally, remember that, like any popular home remedy, more research is needed to reach definitive conclusions on the effects of onion juice as a treatment for hair loss.
