If a client is unsure about their allergy to chemicals used in lash extensions, what is the best course of action?

Conducting a patch test is the best course of action when a client is unsure about their allergy to the chemicals used in lash extensions. A patch test allows the technician to apply a small amount of the product in a controlled manner, usually on a discreet area of the skin, to check for any adverse reactions before proceeding with the full application of lash extensions. This is crucial because it helps identify potential allergies or sensitivities that the client may have to the products, ensuring their safety and comfort.

Choosing to apply the extensions without testing could lead to allergic reactions that can cause discomfort, irritation, or more severe health issues for the client. Consulting with another technician may not provide conclusive information about the client’s potential allergies, as each technician may have different perspectives or product knowledge. Skipping chemical products entirely would limit the options for lash extensions and may not always be necessary if a patch test indicates that the client can safely use the products. Therefore, performing a patch test is the most effective way to ensure the client's safety and satisfaction with the treatment.
