Cyperus rotundus oil works. In a randomized clinical study in Aesthetic Surgery Journal, it reduced underarm hair as effectively as an Alexandrite laser, beat the laser on white hair, and no side effects were detected. Two more randomized trials, with 153 and 308 participants, found significantly reduced hair growth. Apply Bare Oil after shaving or waxing, twice a day, and regrowth comes back slower, finer and lighter, on every hair color.
Shaving forever. Waxing forever. Paying for laser forever. Not anymore.
You shave, and by morning there's stubble. You wax, and in three weeks you're booking again. Laser quotes you thousands for a series of sessions, and if your hair is blonde, red or gray, it usually can't treat it at all.
Every one of those methods removes the hair you have. None of them touch the hair that's coming back. That's the gap cyperus rotundus oil closes, and it's why it's the hair inhibitor oil everyone is talking about.
Head to head with an Alexandrite laser. The oil held its own.
In 2014, Aesthetic Surgery Journal published a randomized clinical study titled "Topical Cyperus rotundus oil: a new therapeutic modality with comparable efficacy to Alexandrite laser photo-epilation." 65 people with unwanted underarm hair were randomly assigned to cyperus rotundus oil, saline, or a GentleLase Alexandrite laser. Results were measured three ways: hair counts, independent professionals, and patient self-assessment.
"Cyperus rotundus essential oil is as effective as the Alexandrite laser for decreasing the growth of axillary hair (both dark and white)."Study conclusion · Aesthetic Surgery Journal, 2014 · PubMed 24408514
Prospective, randomized pilot study (level of evidence 3).
And it's not just one study
The same research team has tested topical cyperus rotundus oil in larger randomized trials. Hair reduction showed up again and again.

"Honestly never thought an oil would really reduce my hair but my skin looks so much better and way smoother, not to mention hair is actually thinner and taking longer to come back. It's def a MUST for any girl that doesn't like being so hairy."
"I didnt really think anything of this at first but Ive been using it for a while and I was like...Why is my hair taking SO much longer to grow back?? lol I used to notice regrowth pretty quickly after waxing and shaving and now I can go way longer before I even feel like I need to book another appointment. And the fact that it doubles as a nice body oil is a bonus. My skin stays soft without that greasy oil feeling and im acctually impressed ngl."
"i have softer skin no doubt and thin hairs, works even on the blonde hairs i had forever on my face"
"my skin is SUPER SENSITIVE and usually reacts to almost all skincare but this has worked nicely for me 10/10 sensitive skin approved!!!!"
"I bought this with VERY low expectations tbh. I just wanted something to use after waxing that wouldn't make my sensitive skin freak out. Now I'm over here checking my legs like "where is the hair??" 😭 It's been growing back slower and softer, and my skin feels ridiculously smooth after I use it."

Cyperus rotundus oil results: your questions, answered
Does cyperus rotundus oil really work?
Yes, and the science is in. In a randomized clinical study published in Aesthetic Surgery Journal (2014), topical cyperus rotundus oil reduced underarm hair with no statistically significant difference from an Alexandrite laser, and it beat the laser on white hair. Two more randomized trials, with 153 and 308 participants, found a significant drop in hair growth with the oil. Bare Oil puts that clinically studied botanical into a daily, after-shave routine.
Is cyperus rotundus oil clinically proven?
Cyperus rotundus oil is clinically proven to match laser on underarm hair in a randomized study: 60 people completed it, the oil and Alexandrite laser showed no significant difference overall (P>.05), and the oil was significantly better on white hair (P<.05) (PubMed 24408514). Two later randomized trials also recorded significantly reduced hair growth in the oil groups (PubMed 34618367, PubMed 35290702).
How fast will I see results?
Week 1: skin feels softer, smoother and calmer, with less post-shave sting. Weeks 4 to 8: visible slowing of regrowth, with hair coming back finer and lighter. Results compound with every application, so start today and stay consistent. Full timeline: how long cyperus rotundus oil takes to work.
Does it work on blonde, red and gray hair?
Yes. This is where cyperus rotundus oil wins. Laser targets pigment, so white, blond and gray hair usually can't be treated with laser (UCSF Health). In the 2014 study, the oil beat the laser on white hair, confirmed by hair counts, independent experts and patient self-assessment.
Is it safe? Are there side effects?
No side effects were detected in the 2014 laser study, and no adverse effects were found in the cyperus rotundus oil group of the 308-person 2022 trial. Bare Oil is gentle and fragrance-free, plus vegan, alcohol-free, paraben-free and sulfate-free. Patch test first, as with any new skincare, and check with your doctor if you're pregnant, nursing or treated for a hormonal condition.
Is it permanent?
Bare Oil is a daily hair inhibitor, not a one-time treatment. Use it after shaving or waxing, morning and night, and regrowth comes back slower, finer and less noticeable. Keep using it to keep your results.
Where can I use it?
Legs, underarms, bikini line, arms, stomach, chest, back and face (upper lip, chin, jawline). Never on eyebrows, lashes, scalp or a beard you want to keep. See cyperus rotundus oil for face and the best cyperus rotundus oil for men.
How is Bare Oil different from cheap cyperus rotundus oil?
Bare Oil isn't a single-ingredient dropper bottle. It pairs cyperus rotundus oil with aloe, jojoba, sweet almond oil and acetyl tripeptide-1, so one step replaces three products: aftershave, ingrown hair serum and body oil. It's vegan and fragrance-free, ships from Amazon, and comes with our Smooth or It's Free guarantee. See how to choose the best cyperus rotundus oil.
What if it doesn't work for me?
You're covered. Every bottle comes with our 30-day Smooth or It's Free guarantee, and Amazon orders include a 30-day refund or replacement.
How long does a bottle last?
Each 60 ml (2 fl oz) bottle is about a 60-day supply, used twice a day. That's about 50 cents a day at $29.99, or less with Subscribe & Save.
