Brittle fingernails can have various causes, ranging in severity from 'minor' to 'life-threatening'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose brittle fingernails, we could:
|Vitamin B3 (Niacin) Need||92%||Confirm|
|Vitamin A Need||15%||Unlikely|
|Zinc Need||1%||Ruled out|
|Nephrotic Syndrome||0%||Ruled out|
|Iron Need||0%||Ruled out|
|Anorexia/Starvation Tendency||0%||Ruled out|
|Biotin Need||0%||Ruled out|

Nails can become brittle due to disease or dehydration. Nail dehydration can be caused either by external factors such as chemicals, or by the body being dehydrated and trying to conserve water.
Thyroid diseases may produce brittle nails or splitting of the nail bed from the nail plate.
A deficiency of essential nutrients and minerals such as iron, zinc, vitamins and calcium can cause the nails to become weak.
Over time, the protein loss occurring in nephrotic syndrome will result in a generally malnourished state, causing hair and nails become brittle.
