What is the main contraindication for receiving a gel manicure?

Allergies to UV light serve as a primary contraindication for receiving a gel manicure. Gel manicures typically involve the application of gel polish that is cured under a UV lamp for a specific amount of time. For individuals with allergies to UV light, exposure can lead to adverse skin reactions, making it unsafe for them to undergo this type of treatment.

Considering the other options, while factors like pregnancy, recent nail surgery, and weak nails can pose concerns during nail treatments, they do not specifically prevent someone from having a gel manicure as strictly as an allergy to UV light. In the case of pregnancy, although caution is advised, many nail technicians are trained to provide services safely. Recent nail surgery could require special care or different treatment instead of a gel manicure, but it does not outright contraindicate gel application. Weak nails might necessitate a gentler approach or the use of strengthening products, but again, they do not completely prohibit a gel manicure. The unique nature of UV light allergies makes them a clear and definitive reason to avoid gel services altogether.
