I Tried the TikTok Hair-Slowing Oil for Two Months and I’m Shaving Half as Often
I have been shaving my legs every other day since I was thirteen. It is the single most tedious task in my entire life and I am genuinely tired of it. So when I started seeing Cyperus rotundus oil all over TikTok — a little brown bottle of root extract that people swore was slowing their hair regrowth — I bought one immediately. I picked the SKSOYT version because it had the cleanest formulation (no added fragrance, no fillers). Two months in: I am shaving roughly half as often. I am writing this with one leg propped up on a chair admiring how smooth it still is on day five.
What is Cyperus rotundus oil
It’s an oil extracted from a sedge root — used in traditional Asian and Ayurvedic medicine for ages, and the subject of a real clinical study out of Egypt back in 2007 that found it reduced hair growth in women with hormonal hair-growth issues. The way it works (so I understand it) is that it interferes with DHT at the follicle, which is the same hormone clinical laser hair removal targets. You apply it after shaving or waxing, and over time the regrowth slows and thins out. Not magic — chemistry.
Why I’m hooked
Week one and two: I noticed nothing, was deeply skeptical, almost gave up. Week three: my standard stubble timing started slipping by a day. Week six: clear, obvious, unambiguous — my regrowth was finer (like literally thinner in diameter, you can feel it) and slower. Week eight, where I am now: I am shaving every five or six days instead of every other day, and the post-shave skin is noticeably softer than it used to be. I am converted.
By the second month I noticed my leg hair was growing back finer and slower. I’m now shaving twice a week instead of every other day.Verified buyer
It also doubles as a great post-shave oil
Side benefit I did not see coming: the morning-after razor redness that I had just accepted as part of shaving — it’s gone. The oil is also a moisturizer, so applying it post-shave smooths the skin, calms any irritation, and gets you that just-out-of-a-spa softness. I started using it on my underarms for the same reason and it’s been excellent there too.

A few things to know
This is NOT a depilatory — it doesn’t remove hair you already have. You still shave or wax like normal; this just makes the next round slower and finer. Also, you have to give it time. The first two weeks I really did think I’d wasted my money. If I’d quit at three weeks I’d have missed all the results. Eight weeks is the timeline. There’s also a faint herbal smell when you first apply it (totally gone in about a minute) — fine for me, but flagging if you’re extremely scent-sensitive.
Bottom line
If laser hair removal is out of your budget but you’re sick of shaving constantly, this is the closest thing I’ve found to it. Patience required — but the regrowth curve really does bend.
