Thin fingernails deliver a lot of inconvenience. The causes of this phenomenon can lie both deep inside the body and in external factors. Before you deal with the problem, you need to understand what exactly was the reason for its occurrence.
Internal causes of brittle nails
In 90% of cases, the causes of thin nails on the arms and legs are hidden inside the body. Here are the main ones:
- Genetic predisposition. If the parents or close relatives have thin nails, most likely the child will have the same problem.
- Lack of vitamins and minerals. As a rule, this is due to an unbalanced or malnutrition, as well as taking certain medications.
- Metabolic disorders. This leads to interruptions in the transport of nutrients inside the body.
- Diseases of the internal organs. As a rule, the state of the nail plate is most affected by the endocrine system, gastrointestinal tract, liver, and circulatory system.
- Hormonal disorders. As a rule, nails become thin due to an imbalance of hormones - the genital or thyroid gland.
- Severe stress. Nervous tension leads to the loss of calcium by the body - the main building material for nails.
The internal causes of thin nails on the hands of men and women are the same. This is one of the signals about problems within the body.
Health Details
The condition of the skin, hair and nails is a reflection of the processes occurring in the body. If suddenly the nails on the hands became thin, although this was not previously observed, it was time to take care of your health. Here is what a thin nail plate may indicate:
- Anemia. Due to iron deficiency, tissues, including the nail plate, lack oxygen. This is precisely the common cause of thinning. If, in addition to nail problems, you feel weak or drowsy, go see a doctor.
- Diabetes. When the body does not absorb glucose well (the main source of energy), a deterioration in the functional state of tissues (including nails) is noted. Also, problems with the absorption of glucose can occur due to violations in the pancreas.
- Fungal diseases. This is one of the common causes of destructive changes in nails. The sooner you start treatment, the more likely you are to cope with the problem and restore the nails to a healthy appearance.
- Diseases of the heart and blood vessels. They are usually accompanied by circulatory disorders. As a result, the transport of nutrients is disrupted, nails grow thin and weak.
- Psoriasis. This is an inflammatory disease that affects not only the skin, but also the nail plate.
- Hypo- or hyperthyroidism. This is an insufficient (excessive) production of hormones by the thyroid gland. The result is a slowdown in metabolism and, as a consequence, a deterioration in the functional state of tissues.
Banal overwork is another reason why fingernails become thin. If a person sleeps little, the body's resources are depleted. This leads to disruption of all body systems, which will certainly affect the condition of the skin, hair and nails.
External causes of brittle nails
Not only health can be the cause of thin nails on the hands. Often, relying on good genetics, people begin to neglect the care of the nail plate. Here are some external factors that lead to thinning and brittleness:
- Manicure. Poor tool, inept handling, excessive pressure on the nail plate - all this leads to thinning over time.
- Cosmetics. The application of low-quality varnishes with formaldehyde, as well as the frequent use of nail polish removers with acetone, negatively affects the nails.
- Wrong cream choice. If you use glycerol-based products in a room with dry air (as a rule, this happens in the winter when heaters are working), the substance will draw moisture from the inner layers of the skin and nail. Subsequently, this will lead to thinning.
- Household chores. Gloveless cleaning is one of the most common causes of thinning of the nail. All the fault of alkali and acid contained in household chemicals.
- Climate. Both severe cold and heat are detrimental to the nail plate. Especially if a person neglects to wear gloves and use a nourishing cream.
- Injuries. They can be either random or caused by systematic pressure on the nail plate. An example is playing a musical instrument, the habit of opening something with your nails, and so on.
- Poor environment or hazardous work. Penetration of toxins and heavy metals into the body leads to softening, exfoliation and fragility of nails.
A common cause of thin nails on womenβs hands was the procedure for building and coating with gel varnishes. In addition to the fact that the agents themselves act quite aggressively on the nail plate, mechanical treatment during the procedure also contributes to thinning.
Oil baths
Regardless of the reason why thin fingernails have become your problem, oil baths will help you significantly improve their condition. Pay attention to such formulations:
- third of a glass of warmed olive oil + 2 capsules "Aevit" + 3 drops of iodine;
- third of a glass of warmed olive oil + 5 drops of lemon juice;
- a third of a glass of warmed olive oil + the same amount of apple cider vinegar.
The procedure is as follows:
- Combine all the ingredients in a convenient dish with low sides.
- Wash your hands and hold them under a stream of warm water for two minutes so that the nail plate softens and becomes more susceptible to nutrients.
- Dry your hands and dip the nails in the oil mixture for a quarter of an hour.
