Cardi B's secret to healthy hair is . . . weird 

If you don't have healthy hair, maybe you're not using enough . . . ONIONS??? 

That's Cardi B's secret, and honestly, her hair looks amazing.

She posted two pictures of her hair and said, quote, "My last 2 washes I been boiling onions and using the water to wash my hair. "I used to do this 6 years ago when I started my healthy hair growth journey.  I stopped cause I got really lazy.  It's odorless and I notice that it's been giving a shine to my hair." Apparently, there's actual science behind this.  The high sulfur content in an onion supposedly aids in the regeneration of hair follicles, and its antifungal properties are believed to help maintain scalp health.
