Growth Nail Polish & Remover

(3)

Stronger nails that grow longer. Your everyday polish.

A functional nail polish and remover system that strengthens nails, improves flexibility and reduces brittleness, leaving them hydrated, protected and naturally glowing. If you do not have a specific concern like ridges or discolouration and you simply want to grow long, strong, healthy nails, this is the one we would point you to. One coat, no base or top coat needed.

The real difference is in the removal. Instead of acetone, it includes a nourishing Remover Serum that gently dissolves the polish while hydrating your nails, so removal becomes part of your nail-care routine rather than something that strips them.

Why people love it

  • Naturally hardens soft, weak nails using plant-derived Hexanal
  • No formaldehyde or formaldehyde-releasing ingredients
  • Removes without acetone, so every removal nourishes rather than strips
  • Water-based polish, with very little smell
  • A glossy clear polish you can wear on its own
  • Gentle enough to wear as often as you like

Application: Wash and dry hands. Apply one thin coat of polish and allow 10 mins to dry. Do not get your hands wet for 1 hour after application. Follow with nail oil pen once dry.

Removal: Apply one coat of remover serum to nails. Leave for 5 minutes. Wipe away with a cotton pad. Wash hands thoroughly after use.

The Remover Serum is formulated specifically for our functional nail polish systems and will not remove traditional nail polish. Just as importantly, do not use traditional remover on this polish, as that reintroduces the acetone the set is designed to avoid.

What to expect

Week 1 to 2: Nails start to feel harder and less bendy as Growth Nail Polish builds strength. In our consumer trial, 90% of people experienced less breakage within this window.

Week 2 to 4: With continued use, nails should feel more resilient and break less often.

Ongoing: Real, lasting strength comes as healthier nail grows out and replaces older, weaker nail. Fingernails take 4 to 6 months to grow out fully, so this set works best as an ongoing routine, not a one-off fix.

At removal: The Remover Serum lifts the polish in about five minutes while hydrating, so nails are not left dry or flaky the way they often are after acetone.

Hexanal

Kester Black’s patented hardening agent. A natural, plant-derived ingredient that works by strengthening the nail’s keratin cells, reducing the risk of breakage and splitting. It can help to smooth and hydrate nails, improve strength and flexibility, and promote healthy nail growth.

Our ultimate pairing

For longer, stronger nails.

STEP 1

Growth Nail Polish

The water-based Growth Nail Polish strengthens nails, improves flexibility and reduces brittleness, leaving them hydrated, protected and naturally glowing, in a soft, sheer nude you can wear on its own.

  • Very low smell
  • Includes active ingredients
  • Makes nails look shinier & smoother
  • Promotes healthy nail growth

STEP 2

Remover Serum

Most of the damage in a manicure does not come from the polish, it comes from the acetone used to take it off. Acetone strips colour the way paint stripper strips a wall, and it takes the oils and hydration your nails need with it. Ours does the opposite.

  • Easy, low-mess removal
  • Hydrates and conditions the nail plate
  • Non-stripping, no acetone
  • Promotes healthy nail growth

A completely different approach to nail care.
A two-step system designed to care for your nails, not strip them.

THE DIFFERENCE

Our water-based nail polish is brand new technology, designed to improve the health of nails, not just cover them up.

FAQs

Anyone who wants to grow longer, stronger nails. It is especially good for nails that are naturally soft, bendy or prone to breakage. If you do not have a specific concern like ridges or discolouration, this is our everyday go-to, a healthy polish you can simply wear and enjoy.

Not at all. While it is great for soft, weak nails, it is also just a beautiful everyday polish that happens to strengthen your nails while you wear it. Think of it as the sheer nude you reach for on repeat, working for you the whole time.

No. Many traditional nail hardeners rely on formaldehyde, which can leave nails brittle. Growth Nail Polish uses plant-derived Hexanal instead, so it strengthens while keeping nails flexible.

Around every 5 days. Remove the old coat with the Remover Serum before reapplying. It also suits ongoing use as your everyday polish.

Yes, the Growth Nail Polish is the perfect replacement for regular nail polish, in a formula which is kinder for your nails, is low odour, and can be gently removed with our Remover Serum.

The polish is water-based and made to release with the Remover Serum, so it lifts off with a five-minute wipe and none of the harsh fumes of acetone. They are built to work as a pair. Using another remover means a harsher removal and the stripped, dried-out nails this set is designed to prevent.

It does not wash off. This is not a children's peel-off polish. It wears like a normal polish and lasts around 5 days. When you want it off, you use the Remover Serum.

Yes. Most of the damage from a manicure comes from the acetone used to remove it, and this set takes that step out entirely. The polish is water-based and lifts away with the Remover Serum, which hydrates with sweet almond oil and vitamin E rather than stripping your nails.

No. It is not designed to be worn under traditional polish, because you would then need traditional remover to take it all off, which strips your nails and defeats the point of the set.

Yes. It works on both fingernails and toenails.

We removed the ethyl acetate and butyl acetate that give traditional polish its strong smell, so the polish has very little odour. Low enough to paint your nails in bed. The Remover Serum has a light, fruity scent, nothing like a solvent-based remover.

Yes. Every Kester Black product is vegan and cruelty-free.
