Which method would be inappropriate for clients with sensitive skin?

Strip waxing is often deemed inappropriate for clients with sensitive skin due to the nature of the method itself. This technique involves the application of a wax that is then removed quickly by pulling off the strip, which can cause irritation, redness, or even swelling. Sensitive skin tends to react negatively to such abrasive treatments, as it may not tolerate the trauma from the quick removal of hair, leading to discomfort or adverse reactions.

On the other hand, the other methods listed—electrical epilation, shaving, and laser treatment—may be more suitable for sensitive skin under the right conditions. For instance, electrical epilation targets individual hairs and can be performed gently, while shaving is often less invasive. Laser treatment, when performed by a professionally trained technician, can be tailored to suit various skin types, including sensitive skin, by using specific settings and techniques to minimize irritation.
