I was right in the middle of a demonstration for Pigeon Pose—the kind where your back foot is perfectly visible to the entire front row—when I saw it. That stubborn, yellowish tint on my big toenail was catching the morning light in the studio. Honestly, I felt a flash of heat that had nothing to do with the room temperature; it was the pure, unadulterated embarrassment of being a yoga teacher whose feet looked like they’d been neglected for a decade.

I only share nail care products I have personally tested as part of my own foot care routine. I’m not a doctor or a dermatologist, just a yoga teacher who got humbled by her own toes and decided to do something about it. Full disclosure here.
Being a barefoot professional in Portland means my feet are my primary tools. I’ve always prided myself on my health-conscious lifestyle, but onychomycosis (the clinical term for nail fungus) doesn't care about your organic diet. For months, I tried to ignore it, thinking that if I just scrubbed my yoga mat harder, it would go away. It didn’t. I spent most of last winter trying a generic tea tree oil from the health food store, but after three months of diligent application, my nail looked exactly the same—thick, brittle, and decidedly not pink.
The Mental Hurdle of the Barefoot Teacher
There is a specific kind of irony in teaching a practice centered on 'purity' and 'self-care' while hiding a fungal infection. I found myself adjusting my sequences so I wouldn't have to show my feet too closely. During Savasana, when I would normally walk around and offer adjustments, I stayed near the back of the room. I was worried students would think I was 'unclean,' even though I was washing my feet three times a day. It felt like a betrayal of the body-awareness I preach every single class.
Earlier this year, around late February, I realized that my 'natural' approach wasn't cutting it because I wasn't being systematic. I was just throwing random oils at the problem and hoping for a miracle. I had to face the fact that communal studio floors—no matter how often they are mopped—are high-traffic zones for microbes. If I wanted to keep teaching barefoot without feeling like a fraud, I needed a professional-grade routine that actually addressed the nail plate's permeability.
Transitioning to a Targeted Nail Routine
After my tea tree oil experiment failed, I started looking into formulas specifically designed to penetrate the nail. I eventually started using Kerassentials. It’s an oil-based blend that felt much more 'intentional' than my previous attempts. It contains lavender and tea tree, which I already liked, but it’s formulated in a way that actually stays on the nail rather than just evaporating or rubbing off on my socks. I started applying it twice a day—once after my morning shower and once before bed.
One thing I wish someone had told me earlier: the applicator brush can get a bit gunky if you aren't careful. I started keeping a pack of clean cotton rounds in my bathroom to wipe the nail surface before and after application. I’ve written more about this transition in my post, Humbled on the Mat: My Barefoot Journey with Kerassentials and Serious Foot Care, but the main takeaway is that consistency is everything. You can't skip a day and expect the fungus to just give up.
I also started a bi-weekly photo log. Since toenails grow incredibly slowly—only about a millimeter or two a month—it’s impossible to see progress day-to-day. By taking a photo every two weeks, I could finally see that tiny sliver of healthy, pink nail emerging from the base. It was a slow-motion victory, but a victory nonetheless.
Protecting the Studio and Your Students
When you’re dealing with nail discoloration, you have a responsibility to your community. I became the 'clean mat' evangelist. I stopped using the studio's loaner mats entirely and started sanitizing my own mat with a stronger antifungal solution after every single session. I also made a rule for myself: flip-flops stay on until the very moment I step onto my mat, and they go back on the second I step off. No more walking across the lobby barefoot.
I also explored other options for those who might not like the feeling of oils. A friend of mine who teaches hot yoga—where things get way sweatier—actually preferred a spray-based approach like ProNail Complex because it dries faster. Others prefer to work from the inside out with something like Keravita Pro, which is a supplement rather than a topical. For me, the ritual of the oil was part of the healing process, almost like a localized meditation on my feet.
Patience is a Yin Pose
If you're struggling with this, remember that nail health is a marathon, not a sprint. It’s like holding a deep Yin pose for five minutes; it’s uncomfortable, you want to move, and it feels like nothing is happening, but the change is occurring in the deep tissues. I’m about three months into my serious routine now, and while my nail isn't perfect, the top half—the part that was most yellow and thick—is slowly being pushed out by healthy growth.
I still get occasional pangs of self-consciousness when I’m teaching a packed class, but they are much quieter now. I’ve learned that most students are focused on their own practice, not my big toe. However, taking care of my feet has made me a better teacher because I’m no longer distracted by my own embarrassment. I’m grounded again, literally and figuratively.
Please, if you notice your nails changing color or texture, don't wait as long as I did to get serious. See your podiatrist to make sure you're dealing with a fungal issue and not something else. And if you're looking for natural ways to support your feet in the meantime, check out my guide on the Best Natural Essential Oils for Foot Fungus Prevention. The most important thing is to stop hiding and start treating. Your feet carry you through every Vinyasa; they deserve the same care you give the rest of your body.
If you're ready to stop hiding your feet under the covers and want to try the same oil I’m using, you can find Kerassentials here. It’s been the most consistent part of my morning ritual for months now, and I’m finally starting to feel like myself again—barefoot and all.
