One Sunday evening last month, I was sitting on the edge of the bathtub with my pocket notebook open under the fluorescent light. I was comparing a photo I’d just taken with one from about six months into tracking. I realized something that should have been obvious years ago: the ugly yellowing on my big toe looked absolutely nothing like the weird white spots on my pinky nail. I wasn't just fighting one thing; I was fighting a whole collection of different fungal patterns.
Look, I’m not a doctor. I’m a shift supervisor at a warehouse in suburban Atlanta. I spend ten to twelve hours a day in steel-toe boots. For five years, I just ignored the problem. I hid my feet in boots at work and kept my socks on at home. I was too embarrassed to even mention it to my wife until it got so bad she basically dragged me to a podiatrist. When the prescription topical he gave me did almost nothing after four months, I decided to take matters into my own hands. I started buying supplements and tracking every single Sunday with a photo and a note. I’ve tested over a dozen products across two years now, and my notebook has taught me more than that expensive four-month failure ever did.
The Classic Creep: Distal Subungual Onychomycosis
According to what I’ve gathered from reading and talking to my podiatrist (which you should definitely do before starting any regimen), about 50% of all nail disorders are actually onychomycosis. The most common version—the one I had on my big toe for years—is called distal subungual onychomycosis. In my early photos from two years ago, this looked like a jagged, crumbly yellow wedge starting at the tip of the nail and working its way back toward the cuticle.
This type is a nightmare for a guy in my line of work. The heavy thud of steel-toe boots hitting the floor after a shift is usually followed by the immediate, damp smell of socks that haven't breathed in twelve hours. That moisture is like high-octane fuel for this specific fungus. It gets under the nail plate and starts eating the bed. In my notebook, I tracked this by measuring how far the yellow line was from my cuticle. Earlier this spring, I had a moment of pure frustration where I was flipping back twenty pages in my notebook only to realize the jagged yellow line hadn't moved a single millimeter despite months of expensive drops. It feels like the fungus is anchored in there.
What I learned from my photos is that with this distal type, the damage you see at the tip is old news. The real battle is happening at the base. If you’re tracking your own progress, don't expect the yellow part to turn clear. It won't. You have to watch the new growth coming out of the cuticle. Healthy toenails grow at an average rate of about 3 millimeters per month. If you see a sliver of clear nail at the bottom, you’re winning, even if the top still looks like a rotting corn kernel. It takes about 12 to 18 months for a full big toenail to replace itself, so you have to be patient enough to watch paint dry.
The Chalky Surprise: White Superficial Onychomycosis
About a year into my testing, I noticed something different on my smaller toes. Instead of the deep, thick yellowing, there were these chalky, white patches on the surface. It looked like I’d stepped in powdered sugar or scraped my nail against a concrete floor. This is White Superficial Onychomycosis. The big difference here is that it stays on the surface. It doesn't crawl under the nail bed like the distal type does.
Last summer, I actually tried to scrape some of it off with a clean tool just to see what would happen. It came off like white dust, but the nail underneath was still brittle. Because this type only affects the surface plate, it usually responds faster to supplements and topicals than the deep-seated stuff. However, it’s easy to ignore because it doesn't make the nail thick and painful right away. In my notebook, I noted that these white spots could appear and disappear within a few weeks depending on which supplement I was testing at the time.

The danger with the white spots is thinking they’re just 'dry nails.' I made that mistake for a while. I thought my boots were just rubbing the top of my toes. But the photos showed the spots were spreading to other toes. Fungus is opportunistic. If it finds a home on your pinky, it’s going for the big toe next. Tracking these surface changes helped me realize that a supplement might be working on the surface fungus even if it wasn't touching the deep distal infection yet.
The Rare Warning: Proximal Subungual Onychomycosis
This is the one that really freaked me out when I started researching. Most fungus starts at the tip and moves back. Proximal fungus starts at the cuticle—the 'proximal' end—and moves toward the tip. I never personally saw this on my own feet, but I’ve read that it’s much rarer in healthy people. If you see your nail turning white or yellow starting right at the skin fold at the base of the nail, that’s a different beast entirely.
When I was first starting out, I was just throwing random drugstore creams at my feet. It was a waste of time. My pocket notebook’s verdict was clear: why natural oils finally changed my toes after years of failed drugstore creams came down to how they absorbed into different parts of the nail. You can read about that comparison here: My Pocket Notebook’s Verdict: Why Natural Oils Finally Changed My Toes After Years of Failed Drugstore Creams. If you have that proximal type starting at the cuticle, you really need to be careful and talk to a professional, because that can sometimes point to a weakened immune system.
The Tracking Mistake That Almost Made Me Quit
Here is the deal: most people quit their supplements too early because they don't understand how the nail grows. I almost did the same. I’d look at my Sunday photo and think, 'It still looks yellow and gross.' I’d get frustrated, thinking about the money I was spending. But then I’d look closer at the base of the nail.
The unique thing I’ve noticed after two years of this is that visual progress photos often deceive. Fungal clearing typically starts from the cuticle, but that damaged, stained nail plate from six months ago is still there. It doesn't just 'heal' and turn clear. It has to grow out and be clipped off. I spent a long time thinking a product had failed because the top half of my nail was still thick and yellow. In reality, the bottom 4 millimeters were coming in clear and healthy. If I hadn't been taking photos every Sunday, I never would have noticed that tiny sliver of progress. I would have jumped to the next product and started over for no reason. I actually wrote a whole piece about Why My Toenails Stayed Yellow for Years: The Tracking Mistake I Finally Fixed because it’s the number one reason people fail.
Tracking the specific look of the regrowth is the only way I stay sane. In the warehouse, we track inventory. If the numbers don't match the shelves, something is wrong. My toes are the same way. The photos are my inventory. If I see clear nail at the cuticle, the 'shipment' of healthy nail is coming in. I just have to wait for the old, 'damaged stock' at the tip to move out. It’s a slow process, and it’s honestly a bit ridiculous to be a 44-year-old man with a phone full of toenail pictures, but it beats the hell out of hiding my feet in boots all summer because I’m ashamed of what’s underneath.
Again, I have zero medical training. I just have a lot of patience and a notebook that doesn't lie. If your nails are getting painful, changing color rapidly, or the skin around them is getting red and hot, stop reading blogs and go see a podiatrist. But if you’re just a guy like me trying to figure out which supplement is actually doing something, start taking those Sunday photos. Identify which pattern you’re looking at, and watch that cuticle like a hawk. That’s where the truth is.
