STRONG NAILS

Keratin is the main protein that makes up nails. Naturally produced by the body at the nail matrix, it plays an essential role in nail formation and growth. This fibrous protein gives nails their solid, compact and resilient appearance while maintaining a degree of flexibility. Through the natural keratinization process, cells gradually transform into a protective structure capable of withstanding everyday stress.

Nails are not made up of keratin alone. They also contain water, lipids and various minerals that contribute to their balance and strength. When the keratin structure is of good quality, nails appear smoother, more even and less prone to breakage. Certain nutrients such as biotin, zinc, magnesium and silica are often associated with maintaining normal, strong nails.

When the keratin in your nails is weakened, several signs may appear gradually. Nails often become softer, thinner, and bend easily at the slightest impact. They may also break more quickly or have difficulty growing properly. This fragility sometimes leads to a feeling of nails being sensitive and not very resistant in daily life.

Split or cracked nails are also common signs of a weakened keratin structure. Ridges may appear on the nail surface, while the ends separate into several thin layers. Nails then tend to snag on clothes, break easily, and lose their smooth, uniform appearance.

External aggressions are one of the main causes of nail weakening. Repeated exposure to water, frequent hand washing, or household chores can soften nails and disrupt their natural structure. In the long term, this repeated humidity promotes breaks, cracks, and splitting.

Chemical products such as detergents, solvents, or certain aggressive removers can also alter keratin and dry out the nail plate. Repeated manicures, excessive filing, artificial nails, or aggressive removal of semi-permanent polish also weaken nails. Finally, minor daily traumas such as repeated impacts or nail biting contribute to weakening their natural resistance.

Preserving nail keratin primarily involves simple, regular actions. Hydration plays an essential role in keeping nails flexible and strong. Applying a nourishing cream or oil after washing hands helps limit dryness and protects the nail plate from external aggressions.

It is also advisable to protect hands during household chores to limit prolonged contact with water and chemicals. A gentle manicure also helps preserve the nail structure: it is better to file in one direction, avoid overly aggressive products, and allow breaks between polish or artificial nail applications.

Suitable strengthening treatments can complement this daily routine. Formulas combining hydrolyzed keratin, silica, zinc, or biotin are often used to help strengthen brittle nails and improve their resistance.

Keratin production relies on several essential nutrients. Sulfur-containing amino acids like cystine and methionine directly contribute to the structure of this protein naturally present in nails. They help maintain their daily strength and solidity.

Certain vitamins and minerals also play an important role in maintaining normal nails. Biotin, also known as vitamin B8, is often associated with healthy nails and hair. Zinc, magnesium, and silica are also used in formulas dedicated to brittle nails to support their natural structure.

Dietary supplements containing hydrolyzed keratin, minerals, and vitamins can be integrated into a comprehensive routine dedicated to nail strength. Some formulas specifically combine hydrolyzed keratin, lithothamnium, zinc, and biotin to help reduce brittleness and support nail growth.

Adopting a regular routine helps maintain stronger nails that are less prone to breakage. In the morning, applying an oil or moisturizing treatment helps protect nails from daily aggressions. Wearing gloves during household chores also helps preserve keratin from moisture and cleaning products.

In the evening, it can be helpful to massage nails and cuticles with a nourishing treatment to improve their comfort and flexibility. These simple steps help limit dryness and gradually strengthen the appearance of fragile nails.

Every week, gentle filing helps maintain a regular shape and limit cracks. It is also advisable to space out aggressive manicures and regularly monitor the condition of your nails to quickly spot unusual fragility.

Brittle or splitting nails are common, but some signs warrant special attention. When fragility persists despite appropriate care, it may be helpful to seek professional medical advice to identify any underlying cause.

Significant changes in appearance, such as discoloration, very pronounced ridges, deep cracks, or unusual thickening, should also prompt a consultation. These symptoms can sometimes reveal a nutritional imbalance or a condition requiring specific treatment.

It is also recommended to consult a doctor when nail fragility is accompanied by other symptoms such as significant fatigue, hair loss, or skin problems. Appropriate support can then help to better understand the origin of the problem and implement the most suitable solutions.

Nails often become brittle when their keratin is weakened by repeated aggressions such as water, household products, harsh nail polish removers, or certain manicures. Nutritional deficiencies, fatigue, or mechanical trauma can also contribute to weakening their natural structure.

Yes, keratin plays an essential role in the strength and resistance of nails. This protein constitutes a large part of their structure and helps to give them a stronger, smoother, and less breakable appearance. When keratin is weakened, nails generally become softer and more sensitive.

Detergents, solvents, some acetone-based removers, and harsh household products can weaken nail keratin. Repeated applications of semi-permanent polish, artificial nails, or aggressive manicure removal can also alter the nail surface and promote breakage.
