Nail conditions refer to various issues that can affect the appearance and health of nails. Common problems include fungal infections, which can cause discoloration and thickening, and ingrown nails, where the nail grows into the surrounding skin, leading to pain and swelling. Other conditions may involve changes in nail texture or shape, such as brittle nails or nail pitting. These conditions can result from factors like poor hygiene, underlying health issues, or environmental influences. Treatment options vary depending on the specific condition and may include topical medications, lifestyle changes, or professional care from a dermatologist. Regular nail care can help prevent many issues.
