Weak nails: know the main causes of the problem
Complaints about weak fingernails are very common, which easily break, peel and / or curl on clothing. There is a lot of misinformation on the subject: many people believe that this symptom is exclusively caused by dietary deficiencies or restrictive diets. In today's article, we will learn more about this problem, especially in women, but also in men.
This condition is known as brittle nail syndrome and is in fact a diagnosis of exclusion. As various dermatological diseases can affect the nails and make them fragile (for example, psoriasis, lichen planus and ringworm, people who nail or manipulate excessively, among other less common conditions), diagnosis of the syndrome of brittle nails is only possible when there is nail fragility in the absence of dermatological nail disease.
When examining the nails, the dermatologist is able to verify if the nail changes that usually accompany this problem are present. In general, there is distal defoliation of the nails in two or more layers or ridges perpendicular to the root of the nail. The correct diagnosis must therefore be made through dermatological examination, history and exclusion of other causes.
The causes of fragile nails are varied, but the vast majority of patients develop the condition due to habits and hobbies involving trauma of the nail. To understand better it is worth knowing that our nails are formed by a protein called keratin. Their consistency is the result of chemical reactions that naturally occur in the structure of this protein. It works as a glue, which joins these keratin fibers, leaving the nail with the consistency that we know.
The constant trauma of the nails can lead to a deficiency of this glue, especially when there are habits such as handling of chemicals, constant exposure to the water, vibrations transmitted by musical instruments, as is the case of violinists, keyboardists, typists, etc.
In the vast majority of cases, with few exceptions, such as surgeries of the digestive tract and severe nutritional deficiencies, changes in diet do not harm the nails. The confusion occurs because the main treatment of brittle nails is made with nutritional supplementation of biotin (vitamin B7), which can lead to an improvement of these frames. However, this has no value if it is not associated with nail cutting, moisturizing, and changing the habits that trigger the process.
