Understanding Adverse Nail Conditions: Contraindications for Treatments

Question
Can you explain what is meant by the term adverse nail condition  

Answer
hi jags
my understanding of an adverse nail condition would be something that would be contra indicated, ie, something that would stop them having any nail treatments.
most contra-indications are things that are either contagious or conditions that would cause pain or injury/harm to the client.
hope this helps!
