Wondering which nail polish to buy for little ones? So were we! We purchased and tested 6 of the top kids' nail polishes for 2021 to find out. Many nail polishes geared towards kids have fun, quirky colors, and claim to have more health-conscious formulas. For this reason, they may be better for pregnant women or anyone looking to reduce the number of harmful chemicals in the home. After using all the polishes on ourselves and a 10-year-old tester, we evaluated each brand based on metrics such as health, color quality, and ease of application. We selected our favorite brands to recommend to you here.

Best Overall Kids Nail Polish

Formula: Nitrocellulose based | Accessories: None
Vivid color

Vegan and cruelty-free
Chemical base
Strong smell

Karma Kids Box Set is a collection of four hues of organic nail polish from the Karma Organic company. The polish is "7 free" - meaning they are free of 7 toxic chemicals that are historically found in traditional polishes. Karma Organic promotes them as suitable for pregnant women, cancer patients, children, and anyone else who would like to limit the number of harsh chemicals they encounter. When applying, the polish offered good coverage after just one coat. However, to get a completely opaque color, Karma recommends using two. In terms of durability, all the colors in the Karma Kids box set impress us with how long they stay on, outlasting most of the competition. We tested the neon themed set, but Karma Organic has a wide variety of colors to choose from.

Despite being 7-free, the nitrocellulose-based formula gives off a strong odor when the bottle is open, indicating that there may still be some harsh chemicals present. We also found that the liquid is a bit thick straight out of the bottle and does not apply as smoothly as some others. However, if you are looking for a nail polish that may reduce the number of toxins in your home while still offering bright, durable, and highly pigmented shades, then Karma Kids Box set is a great choice.

Formula: Water based | Accessories: None
Minimal ingredients
Water base
Minimal odor
Streaky application
Chips easily
Slow dry time

Piggy Paint is a kid-oriented nail polish made with a water-based formula. Their slogan "As natural as mud" is printed on every bottle. Compared to other kids' nail polishes we looked at, Piggy Paint has one of the shortest lists of ingredients and skips many of the harshest chemicals typically found in nail polish. We appreciate that there is only a mild odor. It is not abrasive and smells somewhat like the non-toxic acrylic paints many parents buy for kids' art projects. Piggy Paint offers a wide variety of color choices for children and adults alike.

Unfortunately, the absence of the binding chemicals typically used in nail polishes causes a lack of durability and color opacity in this brand. During testing, this polish was usually the first to wear off. We used the color "Mint to Be" and found that at least 2-3 coats are necessary to achieve an even finish. An extra-long dry time for each layer exacerbates an already time-consuming process. If the wait time is unbearable, Piggy Paint recommends blow-drying nails for 1-2 minutes on a low/warm setting to speed the process. Using a hairdryer also helps to reduce chipping. If you want to have a fun spa day with your child, but would like to avoid toxic chemicals as much as possible, then Piggy Paint polishes are probably your best option.

Formula: Water based | Accessories: Nail file and decals
Many colors to choose from
Peel off removal
Water base
Inconsistent application
Slow dry time

The SuncoatGirl box set offers a water-based nail polish in 10 fun shades. It comes with a nail file and cute flower decal stickers as extras. The tiny 2-ml bottles are perfectly kid-sized and may prevent you from tossing out old bottles of half-used polish when they get too sticky to use. One advantage of water-based polish is that it is salvageable when it gets gummy; just add a single drop of water until the polish reaches the desired consistency and you're good to go. The formula is nearly odorless, and the ingredient list is short compared to other brands we tested. When kids are ready to switch up their look, there is no need for a chemical nail polish remover; the colors just peel off. We like that SuncoatGirl offers innovative alternatives to the traditionally chemical-laden manicure process.

Unfortunately, the peel-off removal method also means unintentional/early peeling can happen. SuncoatGirl colors have a relatively slow dry time due to the water-based formula, and we found that a minimum of two coats was necessary to get an even appearance. Younger children may become impatient with so much waiting and holding still, so this set may be better for older kids. We also discovered that if we have any oil on the nail when painting, it causes the polish to bead up and apply inconsistently. So be sure to start with clean hands to get the best results. Overall, we think this budget-friendly box set is a great way to get lots of shades without spending a fortune.

Formula: Water based | Accessories: Nail file and carry tin
Vibrant color

Slow dry time
Not durable

The Townley Girl Minnie Mouse kids nail polish set comes with three vibrant colors of nail lacquer, one nail file, and a small tin to keep everything in one place. We tested the Minnie Mouse themed set, but there is a wide variety of Disney characters for kids to choose from. We like that the water-based formula includes fewer toxins than traditional polishes. We also appreciate the peel-off removal method for its simplicity and because it means you can bypass the chemical polish remover. All three of the colors included in our set only need one coat to achieve bright and opaque coverage. This set is easy on the wallet and is one of the most affordable options we tested.

Townley polishes are some of the shortest lasting colors of the group. The peel-off formula is convenient but also leads to chipping and possibly early removal. After applying a single coat to our nails, the color started to come off after just a few hours and was entirely gone the following day. Despite claiming faster dry time, we found that Townley Girl takes longer to dry than most other polishes in our review, so it may not be suitable for antsy toddlers who have a hard time sitting still. However, if you have a child who loves accessories and bright colors, the Townley Girl Minnie Mouse set is sure to be attractive.

Formula: Nitrocellulose based | Accessories: Nail decals
Smooth and even application
Long-lasting
Fast dry time
Strong odor
Chemical base

The ella+mila Mommy and Me Set will fit right in with your mother-daughter spa day. Their high-quality nail lacquer comes in a set of two color options, one in a large bottle for mom, and one tot-sized bottle for your child. With the smoothest and application of all the polishes we tested, ella+mila colors hold their own against traditional nail polishes, boasting a fast dry time and smooth consistency. All of this is achieved while excluding several harsh toxins. The formula allows for clean lines when applying, and the colors can last over a week in our experience. The polish offers a reasonable level of opacity with just a single coat; however, a second coat makes it look that much better. For a little extra pizazz on your fingers, the set comes with cute flower decals.

ella+mila polishes use a chemical-based formula and claim to be 7-free while providing impressive results. However, it inevitably has more toxins than water-based products, and there is a strong chemical odor when the bottle is open. Like many traditional polishes, you must use a chemical remover to take off the lacquer, potentially introducing even more toxins to your skin. However, suppose a smooth application and long-lasting durability are your top priorities. In that case, ella+mila polishes make a substantial effort to be more health-friendly and are on par with traditional leading polish brands in terms of quality. We recommend them to anyone who wants fewer toxins in their life but doesn't want to drastically switch up their routine.

Formula: Unknown | Accessories: Nail file
Virtually mess-free
No dry time
Intricate designs
Time-consuming
No disclosure of ingredients

Comodoit Nail Wraps offer pre-cut designs with a stick-on application. We think this is an excellent alternative for younger children who are less patient because there is no dry time! There is no risk of spilling the bottle or accidental paint transfer from fingernails onto other surfaces. Applying the stickers is a fast and straightforward process that makes very little mess. We are also very impressed by the durability offered by this set. In our experience, the nail stickers can last over a week without peeling. When correctly sized to your nail, they genuinely look like nail polish. The 8-pack of nail stickers offered by Comodoit wraps is also one of the most affordable options we found.

Because they are precut sizes, the nail wraps may not match all nail sizes exactly. To cut them down to size can be a time-consuming task. We are also a bit concerned that we are unable to find any information on these stickers' ingredients. There is no disclosure on how the manufacturing process, nor what is in the adhesive. If this worries you, then Comodiot Nail Wraps may not be the best option. However, we think this is a great way to get intricate manicure designs in a mess-free package with no dry time.

Formula: Soy-based | Accessories: None
Works on traditional and non-traditional polishes
Low odor
Vegan and cruelty-free
Do not use with soy allergies
May damage household surfaces

ella+mila Soy Nail Polish Remover is an acetone free way to take lacquer off your nails. ella+mila notes that the soy-based formula is designed for use with "natural" nail polishes, but we tried it out on traditional options and found it works equally as well on both formulas. We like that it contains fewer of the very harsh chemicals found in many polish removers and much appreciate that there is only a mild odor when using the product. Thanks to the addition of vitamins A, C, and E, our nails and cuticles were left feeling hydrated and supple after use, as opposed to the dryness you usually experience with acetone-based removers.

Acetone based removers typically start working as soon as the cotton ball touches the paint, but ella+mila's remover needs a minute to work its magic. You must swipe a quick layer over all the nails and let it sit for 20-30 seconds. From there, you can scrub the color with ease. As a soy-based product, this polish remover is not suitable for anyone with allergies to soy. We also caution you not to use this without a paper towel or some other barrier underneath. The formula can damage acrylic or plastic surfaces that it touches(i.e., bathroom or kitchen countertops). However, we found very few downsides to the ella+mila Soy Nail Polish Remover and recommend it as an essential manicure accessory, even if you choose to use traditional polishes.

Analysis and Test Results



The Lesser of Two Evils?
Many polishes geared towards children claim to have fewer toxins. However, there is currently no such thing as "all-natural" nail polish. So while certain brands of kids nail polish may be better than others, there is no guarantee that you can avoid potentially harmful chemicals without giving up colored nails altogether.

For many parents, it is important to know what kinds of chemicals...

Health


All the products we included in our review are "7-free" and this is a manufacturer's standard that strives to be less toxic and thus potentially more suitable for use with children. However, some manufacturers prioritize health more than others. Water-based formulas such as Piggy Paint or SuncoatGirl are our favorites for this metric, as they each have one of the shortest lists of ingredients that cause us concern. Ella+Mila polishes are the most like a traditional lacquer. However, they still claim to be a whopping 17-free.

What is 7-Free?


Many traditional nail polishes have an array of potentially unhealthy ingredients that may have long-term effects. A few polish companies have worked to eliminate the worst of these chemicals from their formulas and claim a "7-free" composition. Others go above and beyond, attempting to eliminate even more chemicals from their formulation. While there is no such thing as "natural" nail polish, we prefer to use colors that are free of at least the seven concerning ingredients listed below.

  • Toluene: a solvent used in paint thinner. It is considered potentially toxic through inhalation and may be harmful to the nervous system.
  • Formaldehyde: most commonly used to preserve and embalm organisms. The vapors from this chemical may be highly irritating, and it is a known carcinogen.
  • Formaldehyde Resin: a derivative of formaldehyde commonly found in coatings and adhesives. While not considered as toxic as formaldehyde in its pure form, it may still be an allergen.
  • Camphor: A chemical that is considered to be poisonous in large doses, causing seizures and disorientation. In nail polish, it acts as a cover for your nails and some feel that deprives them of nutrients, causing dryness and yellow staining.
  • Triphenyl Phosphate (TPHP): a chemical found in many plastics that improve flexibility and acts as a flame retardant. It is a possible endocrine disrupter that may affect your hormones.
  • Xylene: a solvent used to thin paint. It may be irritating to the skin, eyes, and respiratory tract if ingested or inhaled. Too much of it may affect your nervous system, possibly causing headaches, dizziness, drowsiness, tremor, nausea, vomiting, a host of other ailments.

Many of these chemicals give off strong odors and may be potentially toxic to humans via inhalation. Combined, they create that very familiar nail polish scent. So, generally, we take the position that the less you can smell your nail polish, the better. In general, our view is that the fewer concerning chemicals in a nail polish formulation the better, especially when it comes to kids nail polish formulations.

Ease of Application and Removal


Depending on how old your child is, sitting still can be a daunting task. Younger children will greatly appreciate a fast and fuss-free application. Brush sizes are relatively standard across all polishes but dry time and the number of coats needed vary. We found that Ella+Mila has the fastest dry time and the most consistent application on the first try, eliminating the need for two layers. Karma Kids has an average dry time, but only needs one coat. Using SuncoatGirl colors may test a toddler's patience, with sheer coverage and slow dry time.

Stick on nails like the Comdoit Nail Wraps offer a nearly mess-free application, but may take a bit longer to cut the correct size and shape for smaller nails.

Color Quality/Durability


There is a reason manufacturers began to use such strong chemicals: they create a better-looking, longer-lasting polish. We found that the more "natural" a polish claims to be, the more sheer and less consistent the color turns out. This fact is a bummer, but it seems to be a necessary compromise for now. In our review, the two water-based polishes, SuncoatGirl and Piggy Pain, both have very sheer color and somewhat uneven application. Two to three coats are needed to get consistent coverage on the nails. Of the two, SuncoatGirl colors seem to last the longest on our fingernails.

The bright neon colors in the Karma Kids Box Set are a hit with our kid testers. The highly pigmented formula is also one of the longest-lasting lacquers of the group. Comdoit Nail Wraps surprised us with their durability. The pliable plastic material holds tightly to your nail beds until you chose to remove them.

Conclusion


Flashy nails are fun for kids and parents alike, and doing at-home manicures can be a great shared activity. However, it is good to be mindful of what chemicals you and your child encounter from day to day. Some kids' nail polishes are better than others, and we examined each formula's performance and health aspects to help you make an informed decision.
