Cosmetology Practice Test – Pass the Massachusetts State Board Exam (2026 Guide)

The common symptoms of a fungal nail infection primarily include discoloration, thickening, and brittleness of the nails. This occurs when the fungus invades the nail bed, disrupting normal nail growth and health. As the infection progresses, the nails may change color, often taking on a yellow or brown hue, and become noticeably thicker. The brittleness is a result of the nail structure being compromised, making it more prone to damage and breakage.

Understanding these symptoms is essential for cosmetologists, as they may encounter clients with fungal infections and need to recognize the signs to advise proper care or referral to a healthcare professional. The other options may describe symptoms related to different types of skin conditions or infections but do not specifically align with the distinctive features of a fungal nail infection.
