Best Nail Strengthener [Reviews And Recommendations]

There are several reasons why your nails could get weak, stunted and brittle. One of the most common is the chemicals in nail products. Certain gels, lacquers and polishes could weaken your nails. Some habits such as biting nails could also weaken them and keep them from growing even after you stop the habit.

For some people, their diet is the culprit. If your diet is low in vitamin C, iron, calcium, folic acid and proteins, your nails will not be as strong as they should be. For some women, hormonal imbalances can also cause splitting and cracking.

The following nail straighteners are perfect if your nails keep breaking or splitting. We have picked the best strengtheners that deliver fast and safe results.

3 things to consider when buying a nail strengthener

The above are just a small sampling of the many nail strengthener brands we came across. With so many choices available, picking the right strengthener for your nails can be daunting. Here are the three most important things we considered when picking the best. Keep them in mind when you are shopping for a nail polish or gel to combat your brittle nails.

1. Safety

The first thing we checked for any nail strengthener we considered was the ingredients list. The more natural components a nail strengthener has, the better. Look for ingredients like keratin, wheat protein, and natural oils.

Double check to ensure there is no ingredient which you are allergic to. We have seen a few customers complain of a painful reaction to some nail strengtheners.

2. Effectiveness

Most of the nail strengtheners we encountered were all big promises will few if any results. We were careful to pick only those that we were sure would work. The above nail strengtheners not only work well, they also work fast.

The best way to find out if a nail strengthener is as good as the seller says is to read the customer reviews. If too many people say they are yet to get any results after weeks of using it, try another one.

3. Clear vs. coloured

There are generally two types of nail strengtheners: clear and coloured. The one you choose will depend on your preferences. Clear nail strengtheners are ideal for those who don’t want a nail polish look on their nails. If you want to retain your natural nail style, go for this type.

If you don’t want to apply a clear nail strengthener and then apply a nail polish on top, go for the coloured ones. They are 2-in-1 products, acting both as a nail polish and nail strengthener.
