Cosmetology is the study and application of beauty treatments. It encompasses various services, including hair styling, makeup application, skin care, and nail care. Professionals in this field, known as cosmetologists, are trained to enhance a person's appearance through different techniques and products. They often work in salons, spas, or as freelance artists. In addition to practical skills, cosmetologists learn about health and safety regulations, sanitation practices, and customer service. Many cosmetologists obtain licenses after completing formal education and training programs. This ensures they are knowledgeable about the latest trends and techniques in the beauty industry, providing clients with high-quality services.
