BIAB nails, short for Builder In A Bottle, are a type of gel-like nail polish that is applied as an overlay on natural nails or short extensions. This innovative formula is designed to provide extra strength and protection against breakages, allowing customers to grow their nails to new lengths. It is gentler than acrylic, but thicker than regular nail polish and gel polish, creating a smooth, shiny, and manicured finish. BIAB is a soak-off soft gel specifically formulated to be used as an overlay on the natural nail, and it can be used in thin layers as a base coat to provide an added layer of strength to any gel polish manicure. The formula was created to promote natural nail growth and strength, and it is professional-only, so its best to check with your salon whether they provide a BIAB service. BIAB nails can last on your nails for roughly three to four weeks, and they are known to help strengthen natural nails rather than weaken them. While BIAB is not recommended for long extensions, it is suitable for short to mid-length manicures, making it a versatile option for various nail preferences. Overall, BIAB nails are a popular choice for those looking to strengthen their natural nails and achieve a durable, long-lasting manicure.
