Before providing eyelash extension services, what must eyelash technicians test for?

Eyelash technicians must test for allergies before providing eyelash extension services because this is crucial for the safety and well-being of the client. Many eyelash extension products, particularly adhesives, can contain allergens or irritants that may cause adverse reactions. Testing for allergies helps ensure that the client does not have a history of sensitivity to certain ingredients, which could lead to discomfort, irritation, or even more severe allergic reactions.

Being proactive about allergy testing demonstrates a commitment to the client's health. It allows the technician to customize the service according to the client's needs and can prevent potential complications that might arise during or after the procedure. Identifying and addressing allergies before starting the service minimizes risk and enhances the overall client experience.

Options like testing skin tone, client preferences, and eye color do not directly relate to the safety aspects of applying eyelash extensions in the same way that allergy testing does. While understanding client preferences and aesthetics is important, it does not carry the same level of significance as ensuring the client's safety through allergy assessments.
