On the basis of clinical cases, the following interactions are described: worsening of psoriasis, the fact that psoriatic patients wearing artificial nails are more exposed to infections, and allergic risks. The clinical similarities that may exist between nail psoriasis and nail alterations caused by allergic reactions to artificial nails are also emphasized.
