In the scenario where Giovanni notices ingrown eyelashes on a client, which condition does the client have?

The presence of ingrown eyelashes suggests that the client is experiencing trichiasis. This condition specifically involves eyelashes that grow inward towards the eye, which can cause irritation, discomfort, and potentially lead to further complications such as scratching of the cornea.

Trichiasis can occur due to various factors, including improper hair growth direction, previous eyelid trauma, or scarring. It’s essential for professionals to recognize this condition so that they can provide appropriate treatment or recommend corrective measures to prevent further issues related to the eyes.

The other conditions mentioned, such as psoriasis, alopecia, and dermatitis, refer to different issues that do not specifically involve the phenomenon of ingrown eyelashes. Psoriasis is a chronic autoimmune condition characterized by red scaly patches, alopecia primarily relates to hair loss, and dermatitis involves inflammation of the skin, none of which directly correlate with the symptoms described in Giovanni's case.
