1. Nailtiques Nail Protein Formula 2 Plus

Nailtiques has different formulas available for different nail types. The Formula Two Plus was designed to treat soft, peeling, bitten, weak, or thin nails. For people with nails that are too soft and flexible, the Formula 2 Plus can be a good option to harden your nails.

The Formula 2 Plus nail protein provides a smooth, firm nail surface after treatment. Included in the package are two 0.5 oz bottles that will last months with regular use.

Some of the key ingredients in the nail protein include hydrolyzed keratin, and protein with gelatin and calcium to aide in hardening your nails. The other ingredients in the formula allow the solution to be applied smoothly like a nail polish.

Together these ingredients help to build a strong nail foundation by binding the various nail layers. Over time, the nails become resistant to peeling, chipping, and splitting.

Nailtiques recommends using the Formula 2 Plus for six weeks. For best results, you should apply the nail protein daily to allow coats to build up for roughly a week. Using a non-acetone remover, they instruct you to remove the layers at the end of the week to prevent excessive buildup. This process should be repeated each week for the six week duration.

This does require some dedication to apply the nail protein daily; for those with less time available, or those who need more immediate results, other products in this list may suit you better.

Results will vary from each user. Many people with damaged nails from using acrylic nails in the past have had their weakened nails restored after continued use. While many will see results within the first week, others may not see signs for up to six weeks.

Some users have reported discoloration of nails with a yellow/brown color from excessive buildup, but this can be alleviated with using a non acetone remover.

Here are some tips that can assist you with having the best results when using the Formula 2 Plus nail protein. Prior to applying a coat of formula, the nail surface should be completely dry. Excess residue can be removed from your skin with soap and water, while nail protein should also be cleaned from the cuticles to prevent hardening.

For those that want to add a bit of color back to their nails, the nail protein can be used as a base coat, followed by the color of your choice. The next day you can follow up with another layer of the nail protein like normal.

  • Good for people with soft and weak nails
  • Provides a smooth, firm nail surface
  • Can be used as a basecoat to allow color to be added with a polish
  • Includes two 0.5 oz. bottles to allow months of use

2. Quimica Alemana Nail Hardener 0.47oz

The nail hardener from Quimica Alemana comes with two 0.47 oz bottles. Manufactured in Columbia, the formula is designed to help with the correction/prevention of nails that chip, peel, and split. As a nail hardener, it’s designed to strengthen your thinning nails and over time, prevent excessive nail peeling if you’re experiencing those symptoms.

The Quimica Alemana nail hardener can be a good option for people who experience weak nails that are prone to breaking, without needing to reapply the solution as frequently as some of the other nail strengtheners.

Users are instructed to use the product weekly, after each week, you should remove the layer with a non acetone remover and apply a new coat of nail hardener.

The formula is designed to be long lasting, users report the coats lasting for at least a week or longer between applications. Being a concentrated formula, you shouldn’t use the product more than once per week as this can cause a burning feeling/sensation, while others report soreness in their nails.

If at any time you do experience these symptoms, you should discontinue use and use a non acetone remover to remove the product from your nails.

One of the main ingredients in the nail hardener is formaldehyde resin which helps to harden your nails. For the first three weeks, you’re instructed to brush on a thin coat from the middle of your nail to the tip.

This will allow your nails to absorb the product over time in smaller amounts and should help with the possible side effects of the product. After three weeks, you can apply thin coats of the product to the whole nail, taking caution to avoid applying the product directly to the cuticles.

The nail hardener can be used as a base coat for those that would like to use nail polish with the nail hardener. Most users report seeing signs of benefits within one to three weeks of use; several users state that their nails grow longer, stronger, and shinier in a short amount of time.

For users that need a product that’s long lasting, the nail hardener from Quimica Alemana may be the product for you. Unlike other products that may need daily application, you can go more than a week between applications without diminished effect.

The concentrated formula allows you to see results faster for when you need results quickly.

Nail Envy has six different formulas available for various nail types and needs. All six of them can be used as a base coat or as a stand alone treatment with different results depending on the formula used.

The original formula is designed for overall strengthening of weak nails using hydrolyzed wheat protein and calcium to create harder, longer, natural nails. The matte formula works similar to the original formula, but without the additional shiny finish that you will get from the original formula.

Dry and Brittle works to moisturize your nails to increase their flexibility so that your nails don’t break as easily. Harder nails are less flexible and can lead to breakage from common accidents, but with Dry and Brittle, it adds moisture back to your nails.

Sensitive and Peeling was designed with vitamin E and kukui nut oil to help moisturize the nails. The Kukui Nut oil naturally contains vitamins A, E, and F that are commonly used in skin treatment. In addition, the formula also contains aloe vera to help sooth sensitive nails.

As for effectiveness, many users with peeling nails have found better success with the original formula so you may need to try different formulas to find the one that work work best for you.

For those with soft, overly flexible nails, OPI’s formula for their Soft and Thin nail strengthener adds extra calcium and a layer of protection. While some strengtheners can discolor or yellow nails, all of the OPI nail strengtheners leave the nails natural looking. With Soft and Thin, soft nails become harder and healthier over time.

Last on the list of the Nail Envy nail strengtheners is the Healthy Maintenance formula. OPI recommends using this formula once users have gotten the desired result with one of the other formulas and contains a balance of strengthening and protecting ingredients to maintain your nails.

Do note that OPI doesn’t recommend the Healthy Maintenance formula for those using the Sensitive and Peeling formula.

Applying OPI’s Nail Envy formula is fairly simplified and in the middle in terms of time commitment. Initially you need to apply two base coats to your nails, avoiding the cuticles and skin as with other nail strengthening products.

After this initial coat, you apply a single coat every other day, with all of the layers being removed with a non acetone remover weekly. You then repeat the process starting with two coats.

For those with less time, the initial two coasts will last about 7 days without signs of chipping, so there is some flexibility with the formulas. Nail Envy can also be used as a top coat over nail lacquer as well.

  • Six different formulas for various nail conditions/treatment
  • Natural looking nails result from use
  • Long lasting, 2 coats will last for approximately 7 days
  • Available in different colors

As with nail polish, the nail hardener should be used in a well ventilated area; the fast drying formula will allow you to apply a coating of nail polish in a short period of time.

While the nail hardener can strengthen your nails, the titanium dioxide in the nail hardener helps the solution to be spread across your nails easier rather than harden your nails.

On their website they state that you can expect to grow healthy looking nails in 5-7 days but this can vary from person to person as some users have reported seeing results after 7-10 days.

The formula can be easy to use and apply to your nails. Apply a base coat of the hardener and once dried, apply a coat of polish if you’d like to add color to your nails and follow up with a top coat of the formula.

Reapply a top coat as needed, typically once a day and after seven days, use a non acetone nail polish remover and restart the process. The product has some longevity between coatings that help to protect the nails from chipping, splitting, and peeling.

  • Healthy looking nails within first two weeks of use
  • Makes nails more resistant to chipping
  • Repairs damage from using acrylic and gel nails

5. Gena Healthy Hoof Cream

This nail strengthening cream from Gena Laboratories has been claimed to find its origins with horse trainers using the formula on horse hooves as the name implies. The use of nail polish and nail remover over time can take its toll on your nails.

For those with weakened, dry, or cracked nails, Healthy Hoof is supposed to moisturize your nails and cuticles while strengthening them over time with proteins and comes in a four ounce container.

Nail polishes and other acetone based products can dry out your nail cuticles, making them brittle and cracked. Gena Healthy Hoof Cream uses a lot of the same ingredients that you would find in a skin moisturizing cream.

As moisture is added back to your nails, they will become more flexible and will help you avoid breaks in your nails. In addition, the formula contains hydrolyzed wheat proteins that get absorbed into your nails to allow them to be strengthened overtime.

Together, a balance of strength and flexibility will help you grow longer, healthier nails that are resistant to breaks, cracks, and peeling.

Odor-wise, the Hoof Cream has more of an herbal smell, so it can be a nice change from other nail strengtheners on the market. The lavender and rosemary oil within the cream can be soothing, but can be cleaned off easily with soap and water if needed.

Unlike other nail strengtheners, the cream is supposed to be massaged into your nails and cuticles on a daily basis; generally at night before you head off to bed. Many of the ingredients also work well as a skin moisturizer so you don’t have to worry if the cream gets onto your skin.

Healthy Hoof is intended to be a long term solution; some users see results after six weeks of continued use up to three months and beyond before they have strong nails that are resistant to breaks, chips, and peeling.

This doesn’t mean that you won’t see more immediate results; it can vary from person to person, but some users have seen nail growth and stronger nails after a couple of weeks.

Ingredient-wise, some nail strengtheners contain formaldehyde compounds to aid in strengthening your nails. Reviewing the ingredients list, Healthy Hoof uses ingredients like castor oil that helps to add moisture to your dried out nails, and hydrolyzed protein to strengthen your nails. Other oils found in the cream include lavender and rosemary oil that have been used in past nail treatments.

Nail Strengthener Buyer’s Guide

In this article, we’ve presented you with ten of the best nail strengtheners on the market, but which one is best for you? Your nails require a balance of strength and flexibility to create healthy looking nails.

Each nail strengthener treats different types of symptoms. Weak nails typically need a formula to strengthen your nails to help them become resistant to breaks. Hardness and strength are similar properties, where strength allows nails to be resistant to breaks, hardness allows them to have resistance against being scratched and dented.

Nails that are too hard can be prone to shattering and splitting. Flexibility deals with how well your nails can bend. Harsh cleaners and solvents can rob your nails of flexibility and make them more brittle. Last on the list of nail properties, toughness is a balance of strength and flexibility.

Nails that are too flexible can be weak and prone to breaks, whereas on the other side, nails that are too strong become brittle the longer your nails become.

What does this mean for you and how can you choose the right nail strengthener that will treat your symptoms? Once you’ve identified your nail symptoms, you can choose a strengthener that will treat your symptoms to create healthy nails. Over time you may need to switch to a different strengthener based on your changing symptoms so that you can find the right balance for your nails.

Primarily there are two types of nail strengtheners: hardeners and hydrators. Hydrators, as the name implies, adds moisture back to your nails. Dehydrated nails can cause the splitting, peeling, and cracking of your nails.

Some common causes of dehydrated nails can come from excessive hand washing, wet work, and exposure to moisture/oil sapping chemicals. Using acetone based products can cause your nails to become more dehydrated, which is why many of the nail strengtheners recommend using non acetone based nail removers.

Hydrating nail strengtheners typically come in a cream form and is applied to your nails, skin, and cuticles. Two of the hydrator nail strengtheners on the list is the Healthy Hoof Cream from Gena, and the Nail Strengthener Cream from Barielle.

These nail strengtheners typically have similar ingredients that you will find in heavy duty moisturizers such as mineral oil, beeswax, glycerin and more. Hinalydrator nail strengtheners are a good option for people with nails that may be peeling or brittle.

Compared to the hardening type of nail strengtheners, hydrator users typically start to see results in months rather than weeks. Hydrators need to be used for long term treatment to be effective; moisturized nails have increased flexibility compared to dehydrated nails.

Hardeners on the other hand use nail hardening ingredients like calcium and formaldehyde. These types of nail strengtheners are best for people with weak nails, and those with nails that break easily.

Over time, the hardeners strengthen your nails to make them less prone to splits and breaks. Nail hardeners come in two varieties, cross-linking hardeners and reinforcing hardeners.

Cross-linking hardeners work directly with the protein in your nails and typically include formaldehyde and calcium in their ingredients list. Some of the nail strengtheners in this list that would fall under the cross-linking side would be the Quimica Alemana nail hardener, and Nail Tek’s Nail Strengthener Xtra.

Reinforcing hardeners on the other hand, coat the top of your nails and often have ingredients that include nylon, and sulfhydryl protein. These products typically have you apply the strengthener as a top coat where the nails harden, but typically need to be reapplied frequently to protect your nails.

Opposed to the hydrator nail strengtheners, you will see signs of improvement more immediately. However, the solution needs to be reapplied frequently to be effective and prolonged use can cause your nails to become brittle.

Once you’ve identified the type of damage to your nails, you can choose a nail strengthener that will work hard to repair and strengthen your nails back to a healthy, stronger, more flexible form.

Final Thoughts

Finding the right balance can be hard, but with time and patience you can have the nails you’ve always wanted. The key is understanding that you may need to change the type of nail strengthener that you’re using to maintain the balance between strength and flexibility.
