Which nail condition is characterized by a rough appearance due to brittleness?

The condition characterized by a rough appearance due to brittleness is onychorrhexis. This condition manifests as longitudinal ridges and splits in the nails, which lead to a brittle texture. The structural integrity of the nail is compromised, resulting in a rough and uneven surface.

Onychorrhexis can be caused by various factors including excessive exposure to moisture, harsh chemicals, or underlying health issues. It is important for manicurists to recognize this condition as it may require specific care and treatment, focusing on hydration and strengthening therapies to improve the health and appearance of the nails.

Nail psoriasis, plicatured nail, and pincer nail have distinct features that do not specifically align with brittleness or roughness. Nail psoriasis typically presents with pitting and discoloration, while plicatured nails involve an unusual folding of the nail plate. Pincer nails are recognized by their inward curve toward the center, which contributes to their unique shape but not necessarily a rough texture. Understanding these nuances helps in providing appropriate care and advice to clients regarding nail health.
