Nail extensions are cosmetic enhancements applied to natural nails to create a longer and more aesthetically pleasing appearance. They can be made from various materials, including acrylic, gel, or fiberglass. Nail extensions are typically applied by a trained nail technician and can last several weeks with proper care. The process involves preparing the natural nail, applying the chosen material, and shaping it to the desired length and style. Nail extensions can be customized with different colors, designs, and finishes, making them a popular choice for special occasions or everyday wear. Regular maintenance is required to keep them looking their best.
