What should a technician do if they encounter an allergic reaction during hair removal?

When a technician encounters an allergic reaction during hair removal, the appropriate response is to discontinue the treatment and apply a cold compress. This is the correct approach because it prioritizes the client's well-being and helps alleviate discomfort caused by the reaction. The cold compress can soothe the affected area, reduce inflammation, and provide immediate relief, which is critical in managing an allergic response.

Continuing the treatment in an attempt to minimize discomfort is not advisable, as it could exacerbate the reaction and lead to further complications. Using a stronger product might worsen the situation by increasing irritant exposure. Additionally, consulting a physician while continuing treatment does not allow adequate time for the allergic reaction to settle and could potentially lead to greater discomfort or harm for the client. Discontinuing treatment is the safest and most responsible action to take in such situations.
