What is a common sign of an allergic reaction to eyelash extensions?

The presence of itching or redness around the eyes is a well-known indicator of an allergic reaction in the context of eyelash extensions. When a client is sensitive or allergic to the materials used in the adhesive or the extensions themselves, the body's immune response may trigger skin irritation, leading to redness, swelling, or itching in the affected area.

This reaction can occur as a result of the body trying to protect itself from substances it mistakenly identifies as harmful. It’s essential for both the practitioner and client to recognize these symptoms, as they can inform adjustments in technique or materials used.

Other potential signs of irritation or reaction, such as discomfort or rash, could also be factors to consider, but the prominent symptoms listed make itching and redness the most direct indicators of an allergic reaction in this scenario.
