Brittle or fragile nails: what your body is trying to tell you

Why nails are the first thing to cause concern

Nails grow slowly and reflect what happens to the body over time. When they become brittle, it’s usually due to a lack of some essential components in the body. It’s like a house with weak foundations: everything else eventually changes. 

Constant tiredness, an unbalanced diet, chronic stress or overly aggressive habits… the causes are usually multiple and develop silently.

Nutrition: a key that is often overlooked

Nails are made primarily of keratin, a protein that requires specific nutrients to stay strong. 

A deficiency in B vitamins, especially those related to hair and nail health, can cause them to become thinner and more brittle. Similarly, a protein deficiency can slow hair growth and weaken its structure.
