Which cosmetic service would be contraindicated for someone with skin allergies?

Facial treatments would be contraindicated for someone with skin allergies because these services often involve the use of various products and ingredients that may trigger allergic reactions. Individuals with skin allergies may have heightened sensitivity, and applying products to the face can exacerbate their condition, potentially leading to irritation, rashes, or other adverse reactions.

In contrast, hair cutting, manicures, and pedicures generally do not involve the same level of direct exposure to potential allergens found in skincare products. While it's still important to consider individual sensitivities during these services, particularly regarding nail products or lotions, they typically expose less surface area of the skin than facial treatments. This makes facial services especially risky for those with known skin allergies due to the concentrated use of active ingredients and topical applications on the face.
