What is the most effective way to check for nail service allergies?

Performing a patch test prior to application is considered the most effective way to check for nail service allergies because it allows the technician to observe the client's skin reaction to a specific product in a controlled manner. By applying a small amount of the product to an inconspicuous area of the skin, typically on the inside of the wrist or behind the ear, the technician can monitor for any adverse reactions, such as redness, itching, or swelling over a 24 to 48-hour period.

This proactive approach helps identify potential allergies before a full treatment, reducing the risk of a severe allergic reaction during the nail service. While asking clients about their allergies and using a small amount of product on one nail can provide valuable information, these methods do not guarantee that an allergic reaction will be detected in the same reliable manner as a patch test. Waiting for clients to mention reactions is not a preventive measure and could result in someone having an allergic reaction during the service without prior warning.
