7 Best Nail Hardener Without Formaldehyde (June 2022) Reviews

How do you strengthen nails that crack and peel? The best nail hardener should not contain formaldehyde. Instead, it would be best to choose a natural or non-toxic nail strengthening agent.

Formaldehyde is a stench. Formaldehyde is all around us in building materials such as particleboard. It is a preservative and fungicide that can be used to embalm. It can cause respiratory problems and even leukemia, so it is important to limit your exposure. (1)

It is not permitted in top-quality nail polish brands. The majority of nail polish brands are at least three-free and avoid formaldehyde (dibutyl phthalate) or toluene.

As you read the reviews of nail hardeners below, you will see that these products do more than the minimum to protect your health. These are our top picks.

We love this brand of nail products because it is 7-free. They don’t use formaldehyde or formaldehyde-resin, toluene, camphor, DBP, DHP, xylene, TPHP, formaldehyde resin, or toluene. They are also certified vegan and cruelty-free, and they are manufactured in the USA.

Maybe you are already familiar with the “mommy and me” nail polishes that they make for children and parents. In addition, you might be a fan of their wide selection of chip-resistant colors that they continually add to.

Their nail strengthener is great for strengthening weak nails. It will take approximately a month for splitting or peeling nails to heal. It smells amazing!

This is how it works: Apply one coat to the nails, and wait for a week before removing it. Then, they recommend using a non-acetone removal product. Next, apply a single coat of nail strengthener after cleaning them. Then, remove it a week later.

Here’s the fun part. Put one coat during the third and fourth week and take it off on the third day. Then, put on another coat, wait three days, and repeat the process.

You can use the nail strengthener to cover colored enamel after four weeks.

Check out the positive reviews if you are skeptical. It was described as “it doesn’t chip one bit yet” and “it feels silky smooth on my nails.” In addition, it is said to improve the appearance of brittle nails significantly.
