You’ve probably seen it buried at the bottom of an ingredient list on a high-end hair mask or a pricey body lotion. It sounds exotic. Astrocaryum murumuru. Most people just gloss over it, assuming it’s just another trendy botanical oil like coconut or argan. But honestly? Murumuru butter is a completely different beast. It’s dense. It’s waxy. And if you’re dealing with hair that looks like a bird's nest or skin that flakes the second the humidity drops, these murumuru butter benefits might actually be the missing piece of your routine.
It comes from the seeds of the Murumuru palm tree, which grows wild across the Amazon basin, specifically in Brazil. The locals have used it for ages. They know something we're just catching on to: this stuff is a moisture powerhouse that doesn't just sit on top of your skin. It actually works.
What Is Murumuru Butter, Really?
Basically, it’s a fatty acid goldmine. If you look at the chemical makeup, it’s remarkably similar to the oils our own skin produces. It’s rich in lauric acid, myristic acid, and oleic acid. That’s a lot of science talk to say it’s incredibly "bioavailable." Your skin recognizes it. It doesn't fight it.
Unlike coconut oil, which can be a nightmare for people with acne-prone skin because it's highly comedogenic (it clogs pores like crazy), murumuru is much lower on that scale. It’s solid at room temperature but melts the second it touches your skin. It’s got this weirdly satisfying, earthy scent that isn't overpowering. If you’ve ever used raw shea butter and hated the "nutty" smell, murumuru is a lot milder.
The Reality of Murumuru Butter Benefits for Hair
Let’s talk about frizz. We’ve all been there. You spend forty minutes blow-drying your hair, step outside into 60% humidity, and suddenly you look like you’ve been licked by a cow.
The reason murumuru is a "holy grail" for curly and coarse hair types is its ability to penetrate the hair shaft. Most conditioners just coat the outside. Murumuru goes deeper. Because it's so high in fats, it fills in the microscopic gaps in your hair cuticle. This seals the moisture inside. It creates a natural barrier.

Why Curly Girls Love It
If you have Type 3 or Type 4 curls, you know the struggle of "shrinkage" and breakage. Murumuru butter gives the hair "slip." This means when you’re detangling in the shower, your comb actually slides through the knots instead of snapping your hair off. It helps define the curl pattern without making it feel crunchy or greasy. You get that bounce.
Color-Treated Hair Protection
Chemical dyes strip the natural lipids from your hair. It leaves it feeling like straw. Using a mask with murumuru helps restore those lost fats. It’s also surprisingly good at protecting hair from sun damage. The Vitamin A content acts as a mild shield against UV rays that normally fade your expensive balayage.
Skin Barrier Repair: Beyond Just Softness
Your skin barrier is like a brick wall. The cells are the bricks, and lipids are the mortar holding it all together. When that mortar cracks, moisture leaks out (transepidermal water loss) and irritants get in. That’s when you get redness, itching, and "tight" skin.
One of the biggest murumuru butter benefits is its high concentration of Vitamin A. We usually think of Vitamin A as Retinol—the stuff that peels your skin and makes you sensitive to the sun. But in its natural butter form, it’s much gentler. it encourages cell turnover and keeps the skin elastic.
- Eczema and Psoriasis: While it’s not a "cure," many people with chronic dry skin conditions find relief because murumuru is non-irritating. It provides a thick, protective layer that stays put longer than watery lotions.
- The "Glow" Factor: Because it’s an emollient, it smoothes the surface of the skin. Light reflects better off a smooth surface. That’s why you look "glowy" after applying it, not just greasy.
Sustainable Harvesting and the Amazon
We have to talk about where this comes from. Murumuru isn't farmed in massive, destructive plantations like some palm oils. It’s mostly wild-harvested. Local communities in the Amazon collect the fallen fruits, crack open the hard nuts, and extract the butter.

This is huge.
It provides an economic incentive to keep the rainforest standing. If the trees are worth more alive and producing seeds than they are as timber or cleared land for cattle, they stay. When you buy products using ethically sourced murumuru, you're quite literally helping fund the preservation of the Amazon.
How to Actually Use It
Don't just go buy a tub of raw butter and slather it on your face if you have oily skin. You'll regret it. You have to be smart about the application.
For Your Face
If you have dry or aging skin, use it as a "slugging" agent. Apply your regular moisturizer, then pat a tiny, pea-sized amount of murumuru butter over the top. This locks everything in overnight. If you’re prone to breakouts, maybe stick to using it on your neck and chest only.
For Your Hair
Use it as a pre-shampoo treatment. Rub it into your ends, let it sit for twenty minutes, then wash. This prevents the shampoo from stripping too much moisture. Or, if you have very thick hair, use a tiny bit as a finishing pomade to flyaways.

For Your Body
The best time is right after the shower when your skin is still damp. The butter will emulsify with the water droplets and soak in way faster. Pay extra attention to elbows and heels. It’s a game-changer for cracked heels.
Common Misconceptions and Downsides
Is it perfect? No. Nothing is.
Some people find the texture too heavy. If you have fine, thin hair, murumuru will weigh it down. You’ll look like you haven't washed your hair in a week. For fine hair, look for "murumuru extract" in a lightweight spray rather than the pure butter.
Also, be wary of "greenwashing." Some brands put "Murumuru" in big letters on the front of the bottle, but when you check the ingredients, it’s 95% mineral oil and 1% butter. Look for it in the top five ingredients to get the actual benefits.
Actionable Steps for Better Results
If you're ready to try it, don't just grab the first thing you see on the shelf. Start by checking your current hair products for Astrocaryum Murumuru Seed Butter. If it’s not there, consider these moves:
- The Patch Test: Buy a small jar of 100% pure, cold-pressed murumuru butter. Test a small area on your forearm for 24 hours. Even natural products can cause reactions.
- The DIY Mix: If your favorite body lotion isn't quite cutting it in the winter, melt a tablespoon of murumuru butter and whisk it into your lotion bottle. It'll give it a massive boost in moisturizing power.
- The Deep Condition: Once a week, apply a murumuru-based mask to dry hair before you get in the shower. The steam from the water will help the fats penetrate the hair cuticle more effectively.
- Lip Care: Use it as a lip balm. It stays on longer than beeswax and actually heals chapped lips rather than just coating them.
Consistency matters more than quantity. You don't need a lot of this stuff because it's so concentrated. A little goes a long way, and your skin barrier will thank you for the extra protection.
