Balanced in warrior III, arm stretched out past my fingertips, weight pressing into the ball of one foot, I caught my own reflection in the studio mirror and there it was: the yellow edge of my big toenail — the one detail my whole approach to nail care had apparently missed — had crept another sliver toward the tip since the last time I'd let myself really look.

Two years into teaching yoga barefoot, six days a week, and I'd built an entire identity around being the person whose feet were fine — good nail care, a clean mat, the whole yoga-lifestyle package. Natural remedies lived in my bathroom cabinet before they lived on anyone's Pinterest board. So finding fungus on my own foot felt less like a health issue and more like a professional contradiction I now had to teach through.
Is This Actually Fungus, or Did I Just Bruise the Nail?
Ogechi — a student who's been in my Thursday morning class for two years and has never once softened a question in her life — was the first person to ask out loud, mid-savasana cooldown, what was going on with my toe. That's usually the first real question anyone has: is this fungal, or did I just jam my toe on a doorframe and the discoloration is trauma working its way out. The two can look similar early on, and I won't pretend I sorted that out myself.
From what I've since read, and I want to be clear I'm not a medical anything, the yellow color happens because the organisms responsible are breaking down keratin, which is what the nail plate is actually made of. They tend to start at the edge farthest from the cuticle — the tip, or the side — and work their way in, which is why that edge crumbles and thickens before the rest of the nail shows any change at all. That matched exactly what I was watching happen to mine.
Why Three Months of Tea Tree Oil Did Nothing
My first move, because I live in Portland and tea tree oil is basically a religion here, was a bottle from the New Seasons on Hawthorne. I dabbed it on twice a day, morning and after my own practice, for a full three months. Nothing changed. If anything the nail looked chalkier by the end than it had at the start.
Here is what I wish someone had told me going in: an oil sitting on top of the nail and an oil actually getting through the nail plate are two completely different things, and rubbing something on the surface doesn't guarantee it goes anywhere past that first layer. That's basically the whole story behind why tea tree oil failed my toenails — mine included. It smells nice. It didn't do anything measurable for three months straight.
Topical Oil or Something You Swallow?
Once the tea tree experiment fizzled, I moved toward products built with actual delivery in mind rather than just a nice ingredient list. Kerassentials was the one I stuck with — oil-based, tea tree and lavender in the mix so it still scratched my natural-ingredients itch, but formulated to actually get past the surface. As someone who spends a lot of class time thinking about proprioception and where my feet are in space, I noticed the texture change on the nail before I noticed any color change, which surprised me.
Realistically you're looking at six to eight weeks minimum before you'd expect to see anything different, and the applicator brush gets grimy fast if you don't wipe it down after every use — something I learned the hard way. If oil droppers aren't your thing, especially if you're rushing barefoot between two studios in one afternoon, a few teacher friends have mentioned ProNail Complex as a spray-based option that skips the brush entirely.
The Pedicure Kit Mistake That Undid My Progress
Most of my actual routine happens in the bathroom of the Craftsman I rent in Sellwood — an old clawfoot tub with a mat inside for grip, a little shelf holding the oil bottles and a pumice stone within reach, the overhead bulb turned low because it's usually dark out by the time I get to any of this. That's also where I made my dumbest mistake.
I used the same pumice stone and the same nail file on the affected toe and every other nail without thinking twice about it, because in my head a pumice stone is just a pumice stone. Cross-contamination between tools is apparently a real way to keep reinfecting yourself or spreading the problem to a nail that was previously fine, and I did exactly that for weeks before it occurred to me to keep a separate file just for the one toe.
Now everything gets rinsed and dried between nails, which sounds excessive until you've watched a problem spread to a toe that used to be your good one. The sour, faintly sweet smell of the diluted vinegar soak I use afterward still catches me some evenings, mostly because it reminds me how long this whole process actually takes.
I Almost Lost My Own Before-and-After Proof
Somewhere in the middle of all this I stopped taking photos. Life got busy, classes got busier, and the log on my phone just sat there untouched for long enough that when I finally picked it back up, I'd lost my clean baseline to compare against. That's the real lesson buried in how to track your toenail healing — noticing the problem is the easy part. Understanding that a nail needs to grow out an entire cycle before it's actually clear is the patience test nobody warns you about, and losing your own before photo makes that wait feel even longer.
Pills, Patience, and Deciding on Internal Support
There was a stretch where I got so anxious about fixing this that I started layering on everything at once — a new supplement, a different oil, a foot soak, a filing routine — without giving any single thing long enough to actually show results. My friend Marisol, who co-organizes retreats with me and has this habit of never just telling you what to do, asked me one question that stuck: what would happen if you just did one thing consistently for a month instead of five things for a week. I didn't have a good answer.
Treating this from the outside with an oil versus from the inside with a capsule turned out to be its own decision, not an obvious one, and I ended up reading around on choosing between internal and external support before I settled on staying topical, mostly because I like watching something work rather than trusting it's happening invisibly. For anyone who wants the inside-out option, Keravita Pro is the one I hear about most, built around garlic and turmeric rather than a topical oil, and it's an easier habit to keep if pills fit your life better than droppers do.
How Your Mat and Shoes Affect Foot Health
Beyond what you're putting directly on the nail, there's a whole layer of foot health that has nothing to do with oils or capsules. How often you're actually cleaning your mat matters more than I gave it credit for early on — a barefoot practice puts your feet right back on the same surface, class after class. What you slide your feet into right after — still damp from a shower, straight into closed shoes — plays its own role in whether anything sticks around. And the thickening at the edge of the nail is genuinely a separate problem from the color, one that took me longer to notice than the yellow ever did.
The One Thing I'd Tell You Mid-Class
If Ogechi asked me today instead of months ago, my answer would be shorter and a lot more direct: stop treating one remedy like it's supposed to work overnight, and give whatever you choose long enough to actually prove itself before switching to the next thing. That's the mistake that cost me the most time, not the fungus itself.
My own nail is close to grown out clean now, and I'm back to teaching without that flicker of self-consciousness every time I lift a foot into a pose. Whether that ends up being Kerassentials for you or something else entirely, pick one approach, stick with it, and take the photo even on the weeks you don't feel like it.
