1. Nail Tek Citra 3 Nail Strengthener – Best Long-Term Solution

New Formula

Nail Tek Citra 3 Nail Strengthener ReviewWhen you have brittle nails, you want an all-in-one solution that’s going to strengthen your nail but also add shine and work with your nail polish. Nail Tek Citra 3 offers the perfect kit to heal your nails and strengthen them with naturally-occuring aldahyde compounds. This is a high-quality solution that works extremely well, even if you have difficult nails that take months to grow.

When I can get the results?

After one week, you’ll see a difference in your nails’ length as well as their texture. You’ll notice how easy it is to apply your favorite polish and avoid breaking your nails on anything you touch. As a formaldehyde-free solution, you also don’t have to worry about the fumes or what the chemicals will do to your nails.

Natural components

With a natural solution, your nails will heal faster and retain their strength and shine for many weeks to come. You can apply Nail Tek Citra 3 to your nails once per week to keep up their strength.

  • High-quality, natural solution
  • Works with your nail polish
  • Provides shine and strength
  • Tad expensive for the amount provided


While we love Nail Tek’s solution, it’s a little bit costly compared to competitors. The included nail file is a great gift, but it doesn’t make the price right. We think that this is a professional nail strengthener that will work on anyone’s nails, however. If you have extremely weak, brittle nails, this could be just the right solution to toughen up your nails and start growing them longer.

Buyer’s Guide to Nail Strengtheners Without Formaldehyde

With a unique strengthening formula that doesn’t use formaldehyde, there are only a few products left that will get the job done right without being too smelly or not providing the right texture. We go over some of the things that you should look for when you’re shopping for a nail strengthener solution.


Best Nail Strengthener Without Formaldehyde - Reviews and Buyer's GuideThis is by far the most important aspect of shopping for different nail strengtheners. The formula should be designed to treat your nail conditions, but you also want to be on the lookout for any type of chemicals that could be included in the ingredients.

Some ingredients to look for include Vitamin E, aloe vera, coconut oil, jojoba oil, and proteins. You should steer clear of any formulas that contain formaldehyde.

Cream vs Base Coats

You’ll see that there is a slight difference in thinking behind strengthening your nails according to those who like nail polish and to those who also want to improve cuticle strength. There are two types of nail strengtheners to look for, including hardeners and hydrators. The hydrators are typically creams that provide a lot of moisturizer to the top layer of your skin and nail. While these don’t provide instant shine, they help to improve the health of your nail over time.


Best Nail Strengthener Without Formaldehyde - Reviews and Buyer's GuideYou shouldn’t have to spend any more than $10 on a good nail strengthener. However, you’ll see some high-priced ones out there. The best deals will be online where you can find and compare a ton of different nail hardener and optimizer products. You can also look at salons to see what kinds of nail strengtheners they use and pick one for your nail condition.


You should always pick a product that has clear packaging and instructions. You want something that’s going to have the right consistency and results for your nail condition as well.

If you have dry or breaking cuticles, then you definitely should go with a hydrator. Otherwise, you may look at hardeners to get the best options for your brittle nails.

How to Pick the Best Nail Strengthener for Your Nails

There are some tips to keep in mind when you are looking at your nails and trying to determine what issues you want to solve first. It’s best when a nail strengthener can heal, hydrate, and harden all at once.

  • What’s causing your weak, brittle nails? You should determine if it’s a medical condition which may not improve with the use of creams and hardeners.
  • Strong nail hardeners shouldn’t be used more than twice per week. However, creams can be used daily.
  • If you feel a burning sensation when you apply it for the first time, then you should wash it off immediately.
  • You should use a moisturizing cream along with a hardener to improve the skin around the nails as well.
  • Some hardeners can have bad long-term effects on your nails. This is especially true when the formula contains any type of chemicals, such as formaldehyde.
  • Hand lotions and cuticle oils can help return the natural luster of your skin around the nail as well.


While nail strengtheners have been around forever, there are a number of different products that may seem like they have the best features and results. You should only pick a product that has been reviewed and tested, so you know what you’re getting. Of the ones on this list, we still really like the Hard As Hoofs product because of its price and high rating. However, if you want a true hardener, then we would go with Prolane’s solution.

Your nails need to be taken care of daily, so even though you may be a hardener, you probably still want some kind of cream to moisturize your cuticles and make sure that they stay safe from breakage.
