You are helped to understand the causes of this fragility and to adopt the best solutions.
Why do we have soft nails?
Nails are made of 90% of keratin, a fibrous protein that gives them hardness and elasticity. When this keratin becomes fragile, the plate becomes thinner, less resistant, and more easily gives way to everyday aggressions.
Recognize a fragile nail
Fragile nails can be symptomatic of a malfunction of the Ungual matrix. They are often the result of a lower quality keratin, a growth of the dark-skinned nails and/or an alteration of the intercellular cement that binds the layers of keratin. The consequences are easily visible and manifest in different ways:
- Nails that fold and turn easily They lose their rigidity when you press it, especially at the ends.
- Nails that split : the nail plate is separated into thin layers.
- Stries that form on the surface of nails These visible lines show an irregular renewal.
- Scrambled and cracked edges : the edge of the nail gives way to any shock.
- Nail polish quickly splinter : the varnish has difficulty hanging because the surface is too irregular.
To know how to harden your soft or fragile nails, you must first understand the causes.
Possible causes
Several factors can explain this loss of strength:
L-exposure to water - crockery, cleaning, hot baths... water infiltrates into the nail, swells and then drys, causing cracks and breakages.
Manicures too frequent or poorly adapted : aggressive image, removal of semi-permanent varnish or false nails with sander, use of acetone solvent... These manicure practices damage nails and weaken them in the long term.
Mechanical and chemical aggressions : nails used as kitchenware or as DIY or garden tools, nails eaten or exposed to aggressive chemicals. All these situations to avoid as much as possible in order not to weaken your nails permanently.
Essential nutrient deficiency Vitamins (including group B vitamins and vitamin B8 or biotin in particular), minerals (sulphur, zinc, iron, silicon) and essential amino acids are essential for the production of keratin and the process of keratinization. If your diet does not ensure these intakes, your nails will be affected.
