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:

|Anorexia/Starvation Tendency||3%||Ruled out|
|Poor Digestion||0%||Ruled out|
|Vitamin B6 Need||0%||Ruled out|
|Vitamin A Need||0%||Ruled out|
