Most people start thinking about toenail fungus in May. They pull out a pair of sandals, look down, and decide something needs to be done about that thick, yellow, crumbling nail before beach season.
By then, they’ve missed the window.
Here’s the part almost nobody explains: even the most effective treatment in the world can’t repair a damaged nail. Nothing can. The discolored, thickened nail you’re looking at is already dead tissue. Treatment targets the infection so that new nail has a chance to grow in clear — and then you wait while it slowly pushes the damaged portion out.
That waiting period is the whole story. A toenail replaces itself roughly once every 12 to 18 months. Which means the treatment you start in late August is the one that shows results by next spring. The treatment you start in May is the one you’re still waiting on in July.
Late summer / early fall — treatment begins while you’re in closed shoes anyway
New nail grows in from the base; the damaged portion slowly moves out
Sandal season arrives with visible new growth instead of a fresh start
If you want clear nails for next sandal season, this is the season to act.
What toenail fungus actually is
Onychomycosis — the clinical name — is a fungal infection of the nail itself, most often caused by dermatophytes, the same family of organisms behind athlete’s foot. It gets in through a small crack in the nail or a break in the skin around it, then settles under the nail plate where it’s remarkably well protected.
You’ll usually notice it in this order:
- A small white or yellow spot near the tip of the nail
- Gradual thickening
- Yellow, brown, or chalky-white discoloration spreading toward the cuticle
- A crumbly, brittle edge
- Separation of the nail from the nail bed
- Occasionally, an odor or discomfort in shoes
It’s extremely common, and it becomes more common with age — about 1 in 5 people over 60 have it, and up to half of people over 70. Anyone who spends time in gym showers, pools, or locker rooms is at elevated risk, as is anyone who wears closed shoes for long hours in the summer heat.
Why it deserves more than cosmetic concern
For most people, toenail fungus is a nuisance and an embarrassment. For some, it’s a genuine medical issue.
If you have diabetes, neuropathy, or circulation problems
An infected nail is a potential entry point for bacteria. A thickened nail can press into the nail bed and create a wound you may not feel. In our diabetic patients, we treat nail fungus as a foot health priority, not a cosmetic one.
It’s also contagious to yourself. Untreated, it commonly spreads to neighboring toes, to the skin of the foot as athlete’s foot, and to other members of the household through shared floors and towels.
Why drugstore treatments usually disappoint
This is the single most common frustration we hear: “I used that stuff for months and nothing happened.”
There’s a structural reason. The nail plate is a dense, layered barrier specifically designed to keep things out. Most over-the-counter topical products simply cannot penetrate deeply enough to reach the infection living underneath it. Published cure rates for topical treatment are modest, and they require daily application for the better part of a year — a level of consistency very few people sustain.
Prescription oral antifungals are considerably more effective. They’re a reasonable option for many patients, though they require bloodwork and monitoring, and they aren’t appropriate for everyone, particularly patients with liver concerns or those taking certain other medications.
That gap — between topicals that often don’t work and oral medications that aren’t right for every patient — is exactly the space laser treatment was developed to fill.
| Approach | The upside | The catch |
|---|---|---|
| Over-the-counter topicals | Inexpensive and available anywhere | The nail plate blocks penetration; cure rates are modest and daily use for the better part of a year is required |
| Prescription oral antifungals | Considerably more effective, and a reasonable option for many patients | Requires bloodwork and monitoring; not appropriate for everyone, particularly with liver concerns or certain other medications |
| Cool Touch laser | Reaches the nail bed without medication entering your bloodstream; no downtime | Typically classified as cosmetic by insurers, so usually not covered; most patients need two to three treatments |

How laser treatment works
At Cherrywood Foot Care, we were among the first practices in the country to use the Cool Touch laser for toenail fungus, and we’ve now been performing this procedure for years.
The concept is straightforward. The laser delivers a tightly focused beam of near-infrared light that passes harmlessly through the nail plate and targets the fungus in the nail bed beneath. It is designed to reach the nail bed where topicals struggle to penetrate, without any medication entering your bloodstream.
The Cool Touch system has one feature we specifically value: it applies a cooling cryogen spray as the treatment reaches its optimal temperature. This allows the laser to deliver energy while keeping the treatment comfortable, which is why we selected this system.
What a visit actually looks like
20–30 minA typical session, start to finish.
No anesthesiaMost patients describe a feeling of warmth, and occasionally a brief pinprick sensation.
No downtimeYou put your shoes back on and go about your day, including driving yourself home.
2–3 visitsMost patients need two to three treatments for best results. No medications, no bloodwork, no drug interactions.
You can also apply nail polish afterward if you’d like — which many patients appreciate during the months when the old nail is still growing out.
Setting realistic expectations
We’d rather be straight with you than oversell this.
Laser treatment targets the infection. It does not instantly restore the appearance of a damaged nail, and any practice that suggests otherwise isn’t being honest with you. What we watch for is healthy new growth beginning to appear at the base of the nail over the first several months, with continued improvement as that new nail advances. Not everyone follows the same timeline.
Results vary from patient to patient. Nails that have been infected for many years, nails that are severely thickened, and patients with circulation issues generally take longer. Some patients see excellent clearing; others see meaningful improvement without complete clearance.
We’ll give you an honest assessment at your consultation based on what we actually see, including whether a different approach — or a combination of approaches — would serve you better.
One practical note on cost
Laser nail treatment is often classified by insurers as cosmetic, so it typically isn’t covered. Many patients are able to use an HSA or FSA, though eligibility depends on your plan — we’d suggest confirming with your plan administrator. We’ll go over the specifics with you before you commit to anything.
Preventing reinfection
Clearing the infection is half the job. Fungus reinfects at meaningful rates, and one of the most common culprits is putting clear new nails right back into contaminated shoes.
A few habits make a real difference:
- Treat your shoes, not just your feet. Antifungal sprays, powders, or a UV shoe sanitizer help considerably
- Rotate footwear so each pair has 24 hours to dry completely
- Wear moisture-wicking socks and change them if your feet sweat heavily
- Never go barefoot in locker rooms, pool decks, or hotel bathrooms
- Bring your own tools to the nail salon, or choose a salon with rigorous sterilization
- Keep nails trimmed straight across and not too short
- Address athlete’s foot promptly — skin infections migrate to nails
The bottom line on timing
A nail takes the better part of a year to fully replace itself. Start now, and you spend the fall and winter in closed shoes anyway — the months when a healing nail is least noticeable — and arrive at spring with something you’re comfortable showing.
Wait until the weather turns warm, and you’ll spend another summer hiding your feet.
Frequently asked questions
Why is late summer the best time to start treating toenail fungus?
Treatment targets the infection, but it cannot repair a nail that is already damaged. You have to wait for new nail to grow in and push the damaged portion out, and a toenail replaces itself roughly once every 12 to 18 months. Treatment started in late August is the treatment that shows results by next spring. Treatment started in May is still in progress in July.
Why didn’t the over-the-counter treatment I tried work?
The nail plate is a dense, layered barrier designed to keep things out. Most over-the-counter topical products cannot penetrate deeply enough to reach the infection living underneath it. Published cure rates for topical treatment are modest, and they require daily application for the better part of a year, which very few people sustain.
Does laser toenail fungus treatment hurt?
No anesthesia is required. Most patients describe a feeling of warmth, and occasionally a brief pinprick sensation. The Cool Touch system applies a cooling cryogen spray as the treatment reaches its optimal temperature, which keeps the treatment comfortable while the laser delivers energy.
How many laser treatments will I need, and is there downtime?
Most patients need two to three treatments for best results. A typical session runs 20 to 30 minutes. There is no downtime — you put your shoes back on and go about your day, including driving yourself home. There are no medications, no bloodwork, and no drug interactions, and you can apply nail polish afterward.
Is laser toenail fungus treatment covered by insurance?
Laser nail treatment is often classified by insurers as cosmetic, so it typically isn’t covered. Many patients are able to use an HSA or FSA, though eligibility depends on the plan, so we suggest confirming with your plan administrator. We go over the specifics with you before you commit to anything.
When will my nails actually look clear again?
Laser treatment targets the infection; it does not instantly restore the appearance of a damaged nail. What we watch for is healthy new growth appearing at the base of the nail over the first several months, with continued improvement as that new nail advances. Results vary — nails infected for many years, severely thickened nails, and patients with circulation issues generally take longer. Some patients see excellent clearing, others meaningful improvement without complete clearance.
How do I keep toenail fungus from coming back?
Treat your shoes as well as your feet with antifungal sprays, powders, or a UV shoe sanitizer. Rotate footwear so each pair dries for 24 hours, wear moisture-wicking socks, never go barefoot in locker rooms, pool decks, or hotel bathrooms, bring your own tools to the nail salon or choose one with rigorous sterilization, keep nails trimmed straight across, and address athlete’s foot promptly since skin infections migrate to nails.
