How Involved Is Cardi B in Developing Her Haircare Brand?

This article draws on our conversation with Cardi B.

Cardi B says her Grow Good involvement goes all the way down to the lab, not just the label. She describes a hands-on process with Revolve that includes product testing, back-and-forth conversations, and calls with labs in Korea, and she says products get changed or sent back if they do not meet her standard.

That approach sits on top of a much older habit. Cardi B says she was already obsessed with keeping her hair healthy before Grow Good existed, and she points to years of trying homemade treatments on herself instead of waiting for a brand to tell her what worked.

How hands-on is Cardi B with Grow Good?

Cardi B says she is involved in everything that shapes the line, from testing formulas to speaking directly with the people making them. In her account, Grow Good is not a case of putting a famous name on a bottle and stepping away; she says she works with Revolve through conversations about the formulas, joins calls with labs in Korea, and pushes for changes whenever something feels off to her.

She also gives a clear standard for what counts as good enough. If she does not like a product, she says they change it. If a formula falls short, she sends it back. That matters because she ties quality to what happens after the first purchase, not to launch-day attention. Her benchmark is whether people come back and buy again, because in her view a second purchase only happens if the product actually works in real life.

Cardi B also says the products were tested in laboratories and on her own hair. That detail tells you where she places trust: not in the celebrity halo, but in repeated use, direct feedback, and reformulation when needed. For someone trying to judge how involved a founder really is, that is the line she draws herself. She presents Grow Good as a brand built through active approval and rejection, not passive endorsement.

What does her own hair history say about Grow Good development?

Cardi B says her own history with hair care explains why she is so demanding about Grow Good products. Before formal product development, she says she was already trying homemade remedies, including boiling onions and experimenting with treatments at home because she cared deeply about hair health.

One example makes that obsession very concrete. Cardi B says her cousin made a garlic hair mask in 2022, and she says her hair smelled like garlic for one year straight whenever she sweat (25:49). That story is messy, specific, and useful because it shows she did not arrive at product development from a branding exercise. She arrived with a long record of putting things on her own scalp and hair, living with the results, and learning what effort actually feels like when you are the person wearing it.

That background also helps explain why she rejects the idea of easy promises. Someone who has already boiled onions and walked around with the aftereffects of a garlic mask is not talking about hair from a distance. In the way she tells it, Grow Good comes out of trial, discomfort, and stubborn attention to results. The products still need lab work and formal testing, but the standard starts much earlier, with what she has already put herself through in pursuit of healthier hair.

How does Cardi B test whether Grow Good products really work?

Cardi B says real testing means using products under the same conditions people actually live in, not under perfect demo-day conditions. Her example is conditioner in braids: she says that in that kind of routine, she could go two months without washing her hair while judging how the conditioner performed (32:39).

That detail matters because it shows what she is checking for. She is not describing a one-wash impression or a quick feel test on freshly styled hair. She is describing performance over time, inside a protective style, where buildup, moisture, softness, and manageability become much easier to judge honestly. If a conditioner holds up there, in her view, it says more than a polished first use ever could.

She connects that same real-world mindset to where she wants Grow Good to go next. Cardi B says she wants the line in every single store, every beauty supply, and she names Target, Ulta, and Sephora specifically. The ambition is broad, but the route she describes is simple: make products strong enough that people use them, finish them, and come back for another bottle. That is the standard she keeps returning to.
