Cardi B’s unorthodox hair care secret will fill your eyes with tears.

The 29-year-old rapper took to Instagram on Friday to reveal that she soaps her hair with boiled onion water.

« My last 2 washes I boiled onions and used the water to wash my hair, » she captioned a photo of her natural hair from behind.

“I used to do this 6 years ago when I started my healthy hair growth journey,” the “I Like It” artist said.

« I quit because I got really lazy. It’s odorless and I notice it gives shine to my hair.

The comments section was full of messages of support from fans who wanted to try the pungent practice for themselves.

“Let me put a pot of onions on rn,” one user wrote.

« I make all of my hair products from real foods and spices…it really works, » said another.

Experts have agreed that longtime Bronx resident, born Belcalis Almanzar, is onto something.

Onions contain « compounds that may help improve dry, damaged hair, » according to a Healthline article on grooming technique.

The vegetable may also promote hair growth, treat alopecia and reverse graying, proponents claim.
