Focus on soft nails: what causes them and what can you do to strengthen them?

5 min to read

Our nails are alive and, like us, they can feel tired and lacklustre. This can result in brittle nails that bend or split easily. It can also reduce the staying power of your nail polish. Now that we've cleared this up, it's time to act - and fast! The Manucurist team is by your side to help you to understand the issue and take the necessary steps to rediscover strong, healthy nails.

Why do I have soft nails?

Let's be clear: soft nails are unhealthy nails. The layers of keratin that form the nail have deteriorated, weakening it and causing it to break or split easily.


How does this happen? Some of the most common reasons are:


  • overexposure to water and/or chemicals that are harmful to your nails (household products, cleaning agents, solvents, etc.),

  • an unbalanced diet leading to deficiencies in vitamin A, vitamin B8, iron, zinc, magnesium and other nutrients needed to produce keratin,

  • using acetone-based nail polish remover, which dissolves the nail's protective layer of oil,

  • using a drill to remove false nails or gel polish, damaging the keratin in the process,

  • applying gel polish to already weak nails,

  • not taking care of your nails.


Now that we've identified what can cause the problem, we can take action. The solutions for soft nails are at your fingertips. You just need to follow a few simple, natural nail care rules to rediscover strong, healthy nails. Follow the guide and say goodbye to weak nails for good 😉

How to strengthen soft, brittle nails

Solving the problem of soft nails is far from a mission impossible: you just have to give up some bad habits and adopt some simple, effective ones instead. Here are our 3 golden rules for strengthening your nails:

A healthy, balanced diet

Did you know...? Your nails don't lie - they mirror your state of health. A poor diet will lead to deficiencies that will directly impact the health of your nails. The priority is therefore to restore a balanced diet containing all the nutrients your nails need to grow.


In addition to this diet, a course of Nail Boost food supplements containing biotin, brewer's yeast, magnesium and bamboo extracts will promote the growth of stronger, healthier nails.

Nail Boost is a concentrate of all the vitamins and active ingredients needed for strong nail growth.

Well-groomed nails that are constantly cared for

Short and nicely filed, please!

Trying to have long nails when they are soft or brittle will only lead to frustration. It is better to keep them short and gently file them while they regrow. Use an emery board specifically for natural nails and always file in the same direction, without going back and forth, so the layers of keratin aren't affected.

Our Emery Board for Natural Nails is a gentle way to keep your nails short and well shaped.

Well nourished and hydrated

Just like skin and hair, your nails need to be nourished and moisturised all year round with natural products suitable for your nail type. Regularly massage a few drops of Green Oil into your nails and cuticles. This complex of 6 essential oils strengthens and deeply repairs your nails and the surrounding skin.


Your nails are formed in a matrix located under the cuticles, which is why you need to take such good care of them. If you want to know more about the structure and function of your nails, read our special article here.

Well-protected nails

Good daily habits

For the benefit of your nails, you need to protect your hands and defend them against external aggressors. Here are a few easy tips you can put into practice:


  • gloves reign supreme when it comes to household chores or handling chemicals that could harm your nails or dry them out;

  • don't wash your hands too often - only when you need to with warm or cold water;

  • stop biting your nails - some bitter nail polish will help if it's too difficult;

  • nails are not designed for scraping, scrubbing or lifting - there are more appropriate tools for that.

A gentle, protective manicure

A manicure can be a great ally in your quest for strong, healthy nails, as long as you follow a regular nail care routine and use healthy products.


Here are our tips:


  • Au revoir acetone! Remove your regular or gel polish using a gentle, acetone-free remover containing sweet almond oil or castor oil to preserve the nail's natural oil and moisturise the surrounding skin.

In less than a minute, our gentle, acetone-free nail polish remover will leave your nails clean and hydrated.

  • Say yes to regular nail-strengthening treatments like our S.O.S. Mask, enriched with D-Panthenol.

FAQs

What deficiencies are soft nails a sign of?

Our nails are a barometer of our state of health. Their condition is particularly dependent on a well-balanced diet that can ensure the vitamins and mineral salts needed for nail growth. Soft, brittle nails can indicate a deficiency in vitamin B8 (or biotin), B12 or C, as well as a deficiency in iron, zinc or magnesium.

How do you take care of soft nails?

Soft nails are fragile, unhealthy nails that need special care. To regain healthy nails, it is important to have a balanced diet, to care for and moisturise your nails on a daily basis and to protect them from external aggressors (humidity, chemicals, harsh manicures, etc.) using a treatment base coat enriched with AHAs.
