Cardi B Keeps Her Hair Growing With This Easy DIY Hydrating Mask

Cardi B is certainly no stranger to DIY: The Grammy Award–winning rapper has shared her go-to concoctions over Instagram stories, gracing her 71 million followers with all the hair-healthy ingredients found in the kitchen (they're kid-approved as well, as she previously slathered on her daughter Kulture's baby curls and coils). 

And recently, Cardi took to her grid to share all the details of her famous DIY hair mask—just four simple ingredients for healthy, hydrated hair. She even swears by the goop for hair growth: "My hair didn't pass my shoulder," she writes in the caption. "With discipline it's like this today." Those of us itching for long, moisturized tresses are fervently taking notes.

First things first: Detangle your hair while it's dry. "It will make detangling easier when [the] hair is wet with conditioner," she explains. As we know, the strands are at their most fragile when wet—just as you wouldn't want to rub too harshly with a towel post-shower, you don't want to be wrestling with any knots mid-rinse.

Then, she adds a ripe avocado, two eggs, a spoonful of mayonnaise (she uses Primal Kitchen's mayo with avocado oil), and what looks like a heaping tablespoon (we're eyeballing, here) of black castor oil to a blender. All of which are great ingredients for healthy hair, really: Avocado contains natural oils that provide shine and antioxidants1; egg yolks have amino acids to help keep strands smooth, nourished, and even protected against sun damage and pollution. Lastly, castor oil has quite the reputation in the beauty space—it's been used for ages in the Caribbean and in India—with some even touting it as a golden elixir for hair growth. 

Blend it all up, and you've got yourself an all-natural, hydrating hair mask. Cardi suggests applying the mask all over your hair—coating every strand—before letting it set. "Keep [it on your] hair for as long as you can," she adds. You can even secure a cap or headscarf around your coated strands if you're worried about transferring any goo (it'll also keep you from running your fingers through your hair, a recipe for frizz).
