J-Tip extensions are similar to I-Tips but are applied using a slightly different technique involving a heated adhesive. The J-Tip is a pre-tipped extension shaped like the letter “J” and is applied by melting the adhesive tip onto the natural hair using a fusion connector. This method creates a durable and seamless bond that blends well with the natural hair. J-Tips are suitable for those looking for a more permanent extension solution that can last several months with proper care.
