How to Use Kerassentials: The Daily Routine, Step by Step
Kerassentials only works if it reaches the nail often enough, for long enough. The label's routine is four applications a day. It sounds like a lot, but each one takes about a minute once you have a system. Here is the routine, a schedule that fits a working day, and the habits that stop fungus from coming back.
What you need
- The Kerassentials bottle (the brush is built into the cap)
- Cotton swabs
- An emery board or nail file, kept only for the affected nails
- Nail clippers, also kept separate
- A small towel for drying between the toes
Using a separate file and clippers for infected nails stops you from carrying fungus to healthy nails.
The routine, step by step
- Wash and dry. The first application of the day works best after a shower, when nails are clean and slightly softer. Dry your feet completely, especially between the toes. Fungi love moisture.
- File the nail surface (once a day). Gently buff the top of each affected nail with the emery board to thin and roughen it. Don't file down to the skin or make it sore. Wipe away the dust.
- Trim. Every week or two, clip the nail straight across and remove loose, crumbly pieces. Less damaged nail means less space for fungus to hide.
- Brush it on. Use the applicator to coat the entire nail, including the edges and the tip.
- Work it in. Put a drop on a cotton swab and work the oil into the cuticle and under the free edge of the nail, where infections usually start.
- Let it soak in. Give it 5 to 10 minutes before putting on socks. Use clean cotton socks.
The label sets the timing as twice in the morning and twice in the afternoon.
A schedule that fits a normal day
| Time | What to do |
|---|---|
| Morning, after shower | File, brush on, swab the cuticle, let it absorb |
| Late morning | Brush on and swab (takes a minute; keep a bottle at work or in your bag) |
| Early afternoon | Brush on and swab |
| Late afternoon | Brush on and swab before you take your shoes off for the evening |
Tie each application to something you already do: coffee, lunch, the commute home. A phone reminder for the first two weeks helps the routine stick.
How to track your progress
Photos tell you more than memory. On day one, photograph each affected nail from above, in daylight, with your phone at the same distance. Repeat every four weeks. What you are looking for:
- A band of clear, pink nail growing out from the cuticle
- A clean line between new growth and the old discolored part
- Thinner, smoother nail as you file and trim
- Less itching and softer skin around the nail
The company says to expect visible change in 9 to 12 weeks. The AAD notes that on a big toe it can take a year or more to see a fully clear nail, so judge early progress by the base of the nail.
Habits that stop fungus from coming back
Treating the nail is half the job. Fungi live in shoes, socks and shower floors, and reinfection is one of the main reasons nail fungus returns. A 2022 systematic review in the Journal of the American Podiatric Medical Association looked at how to sanitize shoes, socks and textiles to break that cycle.
- Treat athlete's foot at the same time. The skin between the toes often reinfects the nail; MedlinePlus explains athlete's foot and how to clear it.
- Wash socks in hot water and change them daily, or twice a day if your feet sweat.
- Rotate shoes so each pair dries out for a day, and use an antifungal spray or powder in them.
- Wear sandals in locker rooms, gym showers and around pools.
- Don't share nail clippers, files or towels.
- Keep nails short and cut straight across.
Common mistakes
- Stopping when it looks better. The visible part may improve before the fungus under the nail is gone. Keep going until the old nail has grown out.
- Applying over polish. Polish blocks the oil. Leave nails bare.
- Skipping the cuticle. The cuticle and the free edge are where the fungus gets in. The swab step matters.
- Treating one nail and ignoring the skin. If you still have athlete's foot, the nail will likely be reinfected.
- Putting socks on wet oil. Give it a few minutes to absorb.
After the nail clears
Once the old nail has been trimmed away and the whole nail looks healthy, many people keep using an oil once a day for a few more months, especially after a long infection. That fits with what dermatologists suggest about preventing recurrence, along with keeping feet clean and dry.

Treating several nails or both feet
If more than one or two nails are affected, use the brush on each one and a fresh cotton swab for each foot, so you don't carry fungus across. A bottle won't last a full month when you are treating many nails, so the 3- or 6-bottle pack makes more sense. If most of your nails are involved, see a doctor first; widespread infections usually respond better to prescription treatment, with a topical as support.
Questions about using it
Can I apply Kerassentials less than four times a day?
The label says four times, and frequent applications keep more of the actives on the nail. If you miss one, just carry on; aim for at least twice a day.
Do I need to file my nails?
It isn't required, but the label recommends it, and thinning a thick nail lets the oil absorb better. Be gentle and stop if it feels sore.
How much should I use each time?
A thin coat over each nail and a drop worked into the cuticle. One bottle lasts about a month on a few nails.
Can I apply it at night instead?
The label suggests morning and afternoon. Adding a bedtime application is fine as long as you let it soak in before getting into bed.
Every bottle comes with the brush applicator. 60-day refund from delivery.
