"Most nail treatments fail for one reason: they never reach the fungus. Water-based liquids sit on top of the keratin plate and evaporate, and a biofilm shields the colony underneath. What I like about this pen is the approach. A lipophilic, oil-based vehicle carries a strong 25% undecylenic acid active into the nail's micro-channels, while propolis helps break down that protective biofilm. It dries fast, the one-way valve keeps it sanitary, and it is easy to stay consistent with twice-daily use. For an at-home option on mild to moderate cases it is well thought out. For a painful, spreading or diabetic nail, always see a professional."
Penetrates the Keratin Plate + Biofilm
An oil-based system built to reach below the surface. Water-based liquids evaporate on top.
Maximum-Strength 25% Undecylenic Acid
The highest concentration available without a prescription. Many pens use weaker actives.
Dries in Under 60 Seconds, No Mess
A precise, fast-drying dose. Others are greasy, slow or drip everywhere.
One-Way Valve Pen + Sterile Brush
Spores cannot travel back into the reservoir. Open bottles re-contaminate with every use.
Product Description
The Novalys Antifungal Nail Pen is a maximum-strength topical antifungal in a lipophilic (oil-based) vehicle, engineered to pass the keratin barrier where water-based formulas evaporate. Twist, brush on, and let it absorb.
Nail problems are stubborn for a reason: the active has to get past the hard keratin plate and a biofilm that shields the fungus underneath. Most surface liquids never do.
This pen pairs 25% undecylenic acid (the highest concentration available without a prescription) with a Vitamin E lipid carrier that absorbs into the nail's micro-channels, and propolis to help break down the biofilm.
A one-way valve pen with a sterile brush keeps it clean, and it dries in under 60 seconds. For clearer, healthier-looking nails with twice-daily use. For external use only.
How to Use
Step 1: Wash and thoroughly dry the affected nail and the skin around it.
Step 2: Twist the base of the pen to release a precise dose. The one-way valve stops anything traveling back up.
Step 3: Brush the liquid onto the nail plate, into the cuticles and under the free edge.
Step 4: Wait about 60 seconds for it to absorb before socks or shoes.
Routine: Apply twice daily, morning and night. Nails grow slowly, so stay consistent for several weeks to months as the healthier nail grows out.
How It Works
Nails resist treatment because of three barriers: the hard keratin plate, a protective biofilm, and formulas that evaporate before they penetrate. This pen is built for all three.
Lipophilic delivery. An oil-based Vitamin E carrier is chemically matched to keratin, so it absorbs into the nail's micro-channels instead of sitting on top.
Biofilm disruption. Propolis helps break down the biofilm that shields the fungal colony, so the active can make contact.
A strong antifungal active. 25% undecylenic acid is the highest concentration available without a prescription.
Fast and sanitary. It dries in under 60 seconds, and the one-way valve pen keeps spores out of the reservoir between uses.
Used consistently twice a day, it supports clearer, healthier-looking nails as they grow out.
Ingredients & Safety
Active: 25% Undecylenic Acid. Delivery: Tocopheryl Acetate (Vitamin E) lipid carrier. Biofilm support: Propolis Extract. All in a lipophilic, oil-based vehicle.
Safety: For external use on nails and the surrounding skin only. Avoid broken or irritated skin, and keep away from the eyes and mouth. Patch test first if your skin is sensitive. Keep out of reach of children.
Please note: This is an over-the-counter topical antifungal, not a prescription treatment. Nail results take time and depend on a healthier nail growing out, and this is not a substitute for medical care. If you have diabetes, poor circulation, or a painful, spreading or worsening nail, see a doctor or podiatrist.

Real stories from people who love how naturally their greys disappear with the Novalys Color Renewing Shampoo, without the damage of box dye.
"I used it the night before a reunion and my greys were simply gone, in the most natural way. No harsh line, no orange, just my color back. It did not stain my forehead like box dye, and my hair actually felt softer after. I still cannot believe this is a shampoo."
"My greys always show first at the temples and my part. Fifteen minutes in the shower and they blend right in with the rest of my hair. The color looks dimensional, not a flat block, and honestly no one can tell I did it myself at home."
"I stopped box dye because it fried my hair. This covers just as well but leaves my hair softer and shinier, not like straw. Six weeks in and my color looks rich while my hair is in the best condition it has been in years. That is the part I did not expect."
"At 63 I was spending a fortune at the salon every three weeks for root touch-ups. Now I stretch it out with this in between, and my roots never give me away. It has basically paid for itself, and my hair feels better than after a box dye."
"I was nervous about mess and stained hands. There is none. No gloves, no stained sink, no stained hairline. I lather, wait, rinse, and my greys are covered. It could not be simpler, and it does not reek of chemicals like the old dyes did."
"I use Dark Brown and it matches my natural shade perfectly, no brassy tone, no flat block of color. It builds a little more each wash so I control how deep it goes. My husband did not even notice I had changed anything, he just said my hair looked healthy."
"My scalp reacts to almost every dye with itching and redness. This one does not. It is gentle, there is no ammonia smell, and my sensitive scalp stays calm. Finally a grey coverage I can actually use without regretting it the next day."
"At 60 my grey roots made me feel older than I am. Two washes in and my color was back, natural and soft. My daughter asked if I had been to the salon. Such a small change and I feel like myself again every time I look in the mirror."
"Let me be honest: it is a color-depositing shampoo, so it builds gradually and you do keep it up, it is not a permanent dye. But that is exactly what I wanted, gentle, natural, no commitment. After a few washes my greys are covered and my hair feels great. For the price and no damage, I am sold."
Individual results may vary. Reviews reflect personal experiences. Color builds gradually with repeated use.

No gloves, no mess, no stains. Just lather, wait, and rinse.
Massage generously through dry or damp hair, from the roots to the ends, making sure every grey is fully coated.
Work it into a rich lather and leave it on for about 15 minutes. Leave it up to 25 minutes for deeper, longer-lasting coverage.
Rinse until the water runs clear, then style as usual. No gloves needed, and it will not stain your skin or your sink.
Pro tip: The longer you leave it on, the richer and longer-lasting the color. Start at 15 minutes, and go up to 25 for deeper coverage. Use it a few times a week: the color builds with every wash and blends more naturally over time.

The Novalys Color Renewing Shampoo works in two ways. Gentle color is deposited with every wash to cover grey and blend with your natural tone, building multi-dimensional color instead of a flat block. At the same time, six botanical extracts, hydrolyzed wheat protein and pro-vitamin B5 condition and strengthen, so hair looks colored and cared for. No ammonia, no PPD, and it will not stain your hands or skin. Just rich, natural-looking grey coverage, wash after wash.

What's Not In It
Most grey coverage forces a trade-off: cover the grey, but fry your hair with ammonia and PPD, stain your skin, and end up with a flat, brassy block of color. This shampoo does it differently. It deposits rich, natural-looking color that blends with your tone in one 15-minute wash, while six botanical extracts and pro-vitamin B5 condition and strengthen. No ammonia, no PPD, no gloves, and no stains. Grey coverage that actually cares for your hair.

It is a color-depositing shampoo that covers grey. You lather, wait about 15 minutes, and rinse. Gentle color coats your greys and blends with your natural tone, building richer coverage with each wash, while six botanical extracts and pro-vitamin B5 condition and strengthen.
Most people see visible coverage after the very first 15-minute wash. The color deepens and lasts longer as you keep using it, since it builds with every wash. Leave it on up to 25 minutes for deeper, longer-lasting color.
Apply generously to dry or damp hair from roots to ends, work it into a lather, and leave on for about 15 minutes. Rinse until the water runs clear, then style as usual. No gloves needed.
No. Unlike traditional dyes, it will not stain your hands, skin, hairline or surfaces. Rinse thoroughly and any excess washes away cleanly, so there is no mess and no gloves required.
Color lasts about 2 to 4 weeks depending on how often you wash your hair. Because it builds with each use, most people simply use it a few times a week to keep their color topped up.
No, and that is the point. It is a gentle, color-depositing shampoo, not a permanent oxidative dye. It builds gradually, has no harsh line of regrowth, and fades slowly over a few weeks, so you stay in control of your color.
No. It is formulated without PPD, ammonia, parabens, phthalates, mineral oil and formaldehyde donors. That is what makes it gentle enough for color-treated and sensitive scalps.
Pick the shade closest to your natural or desired tone: Black, Dark Brown or Light Brown. The color is multi-dimensional and blends, so it looks natural rather than flat. A quick strand test lets you preview it first.
Yes. It is designed to be safe for all hair types, including previously colored hair and sensitive scalps. If your skin is very reactive, do a patch test 48 hours before your first use.
One bottle lasts around 10 to 15 washes depending on your hair length. If you want to stay stocked and save, a bundle is the better value.
