How to harden and strengthen nails

A beautiful manicure can do a lot for your loved ones, even becoming the final touch of any guest look or outfit. In fact, this season the most striking and colorful nail designs have become a full trend, although there is always room for the most classic proposals in shades such as nude, red or black. However, the excessive use of gel polishes, semi-permanent manicures and all the products used to fix the polish can end up damaging the nails and weakening them.

That is why, many times, it is advisable to let the nail breathe and protect it with some strengthening treatment. Even factors such as a poor diet or a lack of calcium and iron can cause them to split more easily. To avoid this, right here we leave you a selection with different moisturizing, repairing and strengthening products with which to care for them and improve their appearance, even without nail polish.

Why do nails break?

Nails are made up of several layers of keratin, a protein that we can also find in our hair and that provides strength and density the greater the amount present. The first layers of the nails are sensitive to various factors and can be affected or cracked by a multitude of them. Some of the factors that weaken the nails are:

  • Eating a poor diet: if you do not consume a balanced and varied diet, rich in protein, vegetables and fiber, it will directly affect the health of your nails and soft nails.
  • Lack of iron or calcium: a lack of these minerals can result in low levels of red blood cells, and this will make your nails softer and more brittle.
  • Deficiency of vitamins A, B12, C, D or folic acid: the lack or shortage of any of these vitamins is closely linked to the quality of the nail and its weakening.
  • Use of poor quality nail polishes: it is important to keep in mind that you have to use quality products if you do not want your nails to weaken excessively.
  • Abuse of permanent enamels: we all know how comfortable and beautiful this type of enamel is, but it is advisable to let the nail rest from time to time so that it can “breathe”.
  • Lack of hydration: low hydration in our body will also affect the quality and strength of our nails.
  • Biting your nails: It’s pretty obvious, but just in case you didn’t know, biting your nails makes them split and crack easily.
  • Genetics: there can always be a genetic component by which you have a predisposition to have weak nails.
  • Very low temperatures: excessive cold will also affect the nail quite a bit, making it drier and more brittle.
