A post shared by Cardi B (@iamcardib)

In an Instagram post, Cardi B shared that she boils onions and uses the water to wash her hair. While you may think that this technique is a peculiar one, many people under the rapper’s post commented that they have done the same in the past. Some even taking notes from Cardi on the way in which she uses onions.

“Verified I have to try boiling the onions.. I was juicing them and left it too long,” commented former ‘Love and Hip Hop: New York’ cast member, Juju Castaneda. “And for an entire year, anytime my hair was blowed out or straightened it smelled like Sofrito.”

Onions surprisingly have some amazing hair benefits.

Using Onion For Hair Growth

Interestingly enough, onions carry components that work wonders for your hair. For starters, they contain sulfur compounds, which improves blood circulation in the scalp. A bonus is that keratin, which is the main protein in hair, is also in sulfur. The sulfur in onions may also help produce collagen. Collagen is widely known top improve skin cell reproduction as well as hair growth.

You may still be a little skeptical to Cardi’s secret weapon. But it has actually been proven that onions help!

In a study done in 2002, participants who washed their hair with onion juice experienced a significant amount of hair growth compared to those who just washed with tap water. Another study done in 2000 instructed participants who had alopecia areata to apply onion juice directly to their scalp twice a day for two months. Just two weeks after the study began, participants started to notice hair growth.

Almost 74% of participants had claims that they saw hair growth increases after four weeks, and almost 87% said the same in a six week span.

Next time you think about going to the store to grab some hair growth pills, just go straught to your cabinets and get those onions out!
