Olá! It's nice to meet you.

Better hair care is finally here.

Our mission is, quite simply, to elevate your hair care ritual with products that are actually (yes,actually!) better for you. We want to start by (re)introducing castor oil to the world, and perhaps a little bit of that Brazilian samba and flair. Our premium oil is sourced directly from Brazil and brings organically-produced, cold-pressed goodness into your life. Most importantly: no additives, ever. That’s our promise to you.

Golden droplet of pure Brazilian castor oil – rich in nutrients for nourishing hair, skin, and lashes

the aumenta promise

Additive-free. No additives, ever. That's our promise to you. We ship only the purest castor oil straight from Bahia, Brazil.

Plastic-free. Born in Brazil, bottled in Brooklyn. Our glass bottles preserve the environment as well as the quality of our oil, because we love a good win-win.

Refillable. Because when you look good, so should our bottle. Refillable and reusable. Oh, and did we mention it also looks good?

A glass dropper dispensing a golden droplet of castor oil against a clean, minimal background. The dropper should appear elegant and premium, positioned above a palm or glass bowl. The oil droplet should reflect warm, natural lighting to highlight its rich, nutrient-dense texture. Emphasize purity, precision, and self-care.

something that (actually) works

We created Aumenta with one goal: real results. Our pure, cold-pressed Brazilian castor oil is naturally rich in ricinoleic acid, a proven ally in strengthening strands, stimulating growth, and locking in deep hydration. What sets us apart isn’t just the quality of our oil, but how you use it - our thoughtfully designed dropper cap ensures clean, targeted application every time. Because effective hair care should be effortless.

Our commitment to purity means you get all the benefits, with none of the compromises. Clean ingredients, visible results, no BS.
