Toenail fungus typically causes yellow, thickened, and brittle nails, while nail psoriasis often shows red, pitted, or ridged nails. Early identification ensures proper treatment and prevents worsening.
Distinguishing toenail fungus vs nail psoriasis can be tricky because both conditions affect nail appearance. While fungal infections are caused by pathogens, nail psoriasis is an autoimmune condition. Correct diagnosis is crucial for effective treatment.
