Your nails peel in layers. They bend when you type. They split as soon as they pass your fingertip, so you cut them all off and start over.
Nailz treats the nail itself, not a coat on top. Ten seconds, twice a day.
Treats, not covers
Stops the peeling
Grows past your fingertip
Twice a day, that's it

How long until I see a change?
Most people say their nails feel less bendy in 2 to 3 weeks.
Length takes longer. The damaged part has to grow out first, and a nail takes 4 to 6 months to fully replace itself. If you want a fix in a week, this is not it.
Is this just cuticle oil?
No. Cuticle oil softens the skin around your nail. This goes on the nail itself, where new nail is made. You can use both.
I tried biotin, hardeners and oils. Why is this different?
Hardeners coat the nail. That is why nails often peel more once you stop. Biotin only helps if you were low on it.
Nailz goes on the nail and stays. No removing, no recoating, no weekly routine.
The pen is not dispensing. What do I do?
New pens need priming. Twist the bottom 15 to 25 times and hold the brush down until it looks wet. That first fill takes a while.
After that, one or two twists per hand is plenty. Still nothing after 40 twists? Message us and we will replace it.

Start my 90-day trial →Questions, answered
How fast will I see growth?
Most people notice peeling stop and nails feel firmer within 7 days, with clear new growth by week 4. Full transformation is a 90-day journey.
Do I need to stop wearing polish?
No. Apply to clean nails morning and night; polish as usual once it's absorbed. Many users treat between manicures.
Is it safe while pregnant or breastfeeding?
Our formula is vegan and gentle, but we always recommend checking with your doctor first if you're pregnant or nursing.
Will it help gel or acrylic damage?
Yes — repairing post-gel and post-acrylic damage is exactly what the stem-cell + biotin formula is built for.
