The 2-Step Kit That Helped 40,000+ Women Over 50 Fix Thick, Yellow, Embarrassing Toenails
Step 1 softens the hard top layer of your nail. Step 2 sends a full-strength antifungal underneath, where the fungus actually lives. Most creams and pens skip Step 1. That's why they don't work.

5 Reasons Women Are Switching
To The NailScience 2-Step
Why 40,000+ women stopped using Kerasal, Kerassentials, and $800 prescription pens.
It Softens The Hard Top Layer Of Your Nail So The Medicine Can Get In
Step 1 is a softener. It's made with urea, lactic acid, and propylene glycol. Doctors use these same three ingredients at their office to thin thick nails. Put it on every night for 14 days. It softens your nail so Step 2 can reach the fungus underneath. Kerasal, Kerassentials, and Jublia skip this step. That's why they stall.
"I could feel the difference in week one. My nail went from rock-hard and thick to pliable — like a normal nail."
Full Strength — Without A Prescription
Step 2 has 25% undecylenic acid. That's the strongest strength you can buy without a prescription. It also has four plant oils: tea tree, oregano, manuka, and clove bud. They hit the fungus from four different angles, so it can't get used to the medicine. No Lamisil pills. No monthly blood tests. No $800 prescription pen.
"My doctor wanted to put me on Lamisil and monitor my liver every 30 days. This kit works, and I'm not poisoning myself to use it."
A 10-Second Routine You Can Actually Stick To
Kerassentials wants you to put it on 4 times a day. Kerasal says twice a day plus filing. Most women quit by month three. Not because the product doesn't work — because the routine is too much. NailScience is 10 seconds in the morning, 10 seconds at night. That's it. The #1 reason people quit these treatments is how hard they are to stick to. We built ours around what women will actually do.
"I brush my teeth, I apply Step 2. Done. Eleven weeks in, my pinkie toe is already 40% clear."
It Works When Other Products Have Already Failed
This kit wasn't built for first-timers. 83% of our buyers already tried 3 or more other products first. Kerasal. Kerassentials. Jublia. Some even tried Lamisil pills. We built the 2-step kit for the women those one-step products left behind. If nothing else has worked for you, that's actually why this one will.
"I added up what I'd spent on Kerasal, two Kerassentials, and a prescription: $612. The NailScience 3-kit was $179 — and I actually have results."
Backed By A 60-Day Money-Back Guarantee
Try the full kit for 60 days. If you don't see a clear nail growing in at the base, send the empty bottles back. We'll refund every dollar. No extra fees. No long phone calls. Kerasal only gives refunds for 30 days. Kerassentials gives you 14 days — and more than 31% of buyers return it. Our guarantee is longer because our records show 94% of women see clear new nail by week 9.
"I bought it half-expecting to return it — I've been burned so many times. Instead, I reordered. My big toe is clearer than it's been in a decade."
"The strongest over-the-counter nail kit I've seen in 20 years."— Dr. M. Caruso, D.P.M., Board-Certified Podiatrist

What 1,304 Customers Are Saying
Real buyers, ages 52 to 71 · not edited, not paid
"I tried Kerasal for 11 straight months. Two bottles of Kerassentials after that. Then a prescription pen that cost me $420. I spent over $600 and had nothing to show for it. Just a thumbnail that looked like driftwood. Six weeks on the NailScience 2-step and there's clear, healthy nail growing in at the base. My husband noticed before I did. I cried in the bathroom."
- Worked after 11 months of Kerasal not working
- Clear nail growing in at the base by week 6
- Saved $420+ vs. a prescription pen
"The honest truth is that Kerassentials didn't fail me — I failed it. Four applications a day for six months is not a routine, it's a second job. I lasted eight weeks before I gave up. NailScience fits into the life of a woman who already has a life. I put it on when I brush my teeth. Morning and night, 20 seconds total. Eleven weeks in and my pinkie toe is almost 40% clear. It's the first antifungal I've ever stuck to long enough to actually see results, and the reason is the routine — not just the formula."
- 10-second application morning & night
- Sticks to it where 4x/day products failed
- Visible clearing by week 11
"I am 67 years old. I have had this problem since my 40s. I have tried every single drugstore product you can name and a few that don't even exist anymore. I bought the NailScience kit fully expecting to return it on day 59 like every other disappointing thing I've bought in the last decade. Instead I just reordered for the second time. My big toe is clearer than it has been since the mid-1990s. I am not hiding my feet this summer and that sentence alone is worth the price of the 3-kit."
- Worked after 20+ years of failed products
- Big toe clearer than it's been since the '90s
- Reordered twice — total satisfaction

Questions Women Keep Asking
How fast will I see results?
Most women feel the nail getting softer in 7 to 10 days. That's Step 1 doing its job. Clear new nail usually starts growing in at the base between week 6 and week 10. A whole new nail takes 9 to 18 months to fully grow in. That's just how long a toenail takes to grow. No product on your skin can speed that up.
How is this different from Kerasal or Kerassentials?
Kerasal is a one-step softener. It has no antifungal. Kerassentials is a one-step oil blend. It has no softener, so it can't get through the nail. NailScience is the only kit that splits the two jobs into Step 1 and Step 2 — the way doctors do it at the office.
I've already spent $400+ on other products. Why is this any different?
Fair question. The difference is the 2 steps — and the 25% undecylenic acid (the strongest you can buy without a prescription). If it doesn't work for you in 60 days, you get every dollar back. So there's no real downside. 83% of our buyers already tried 3 or more other products before this one worked.
Is it safe for diabetics or people on blood thinners?
Yes. NailScience goes on your skin, not in your body. So it won't mess with any pills you take. But if you have diabetes or blood-flow problems in your feet, please check with your doctor first. That's a good rule for any foot product, not just this one.
What if it doesn't work for me?
Send the empty bottles back within 60 days. We'll refund every dollar. No extra fees. No long phone calls. This is the longest guarantee you'll find. Our records show 94% of women see clear new nail by week 9. We'd rather refund the 6% than oversell.
Can I use this on fingernails too?
Yes. The 2-step kit works on any nail — fingers and toes. Fingernails clear faster. They take about 4 to 6 months to fully grow in, versus 9 to 18 months for toenails. That's because they grow about twice as fast.
