Make the consultation part of the appointment, with time for the product’s testing instructions.
Start with the actual product
A shade name tells only part of the story. Our editorial starting point is simple: establish the exact product being used and make space to discuss previous experiences before the appointment. Bringing the packaging or a clear photograph can make that conversation more concrete.
What the guidance says
The FDA advises following package directions and warnings, performing a patch test each time hair is dyed, wearing gloves, and keeping within the stated application time. Its consumer guidance includes salons in the patch-test advice. Read the linked source alongside the instructions for the specific product; this note is not a substitute for either.
Keep a useful service record
A practical record can include the product name, the consultation date, the instructions discussed, and questions that remain unresolved. Avoid reducing a consultation to a signature on a form. The purpose is to leave both the client and the stylist with a clear understanding of the plan.
Know the boundary
A previous reaction is a reason to seek advice from a qualified healthcare professional before another exposure. A salon consultation cannot diagnose an allergy. This short guide concerns preparation and communication; it does not offer a testing protocol or certify a product as safe.
