Name a common type of skin disorder associated with shaving.

Razor burn and ingrown hairs are commonly associated with shaving, making this the most accurate choice for a skin disorder linked to this practice. Razor burn occurs when the skin becomes irritated after shaving, often resulting in redness, discomfort, and sometimes small bumps. It is typically caused by improper shaving techniques, such as using a dull blade, shaving too closely, or shaving against the direction of hair growth.

Ingrown hairs happen when hair grows back into the skin rather than outward. This can lead to inflammation, redness, and in some cases, infection. It is especially prevalent in individuals with curly or coarse hair. Both of these conditions can be directly influenced by shaving habits and techniques, making them key concerns for barbers and their clients.

Other options listed, such as psoriasis and eczema, while they are skin disorders, are not directly caused by shaving practices. Similarly, athlete's foot is a fungal infection that occurs on the feet and is unrelated to shaving. Thus, the connection of razor burn and ingrown hairs to shaving clearly outlines why this choice is the correct one.
