Split ends occur when the protective outer layer of the hair, called the cuticle, becomes damaged and the inner layers of the hair are exposed. This can cause the hair to become dry, brittle, and prone to breakage. Trimming split ends can help to improve the overall health and appearance of the hair.
There are a few different ways to trim split ends. One method is to use a pair of sharp scissors to carefully cut off the damaged ends of the hair. Another method is to use a split-end trimmer, which is a specialized tool that can quickly and easily remove split ends. Whichever method you choose, it is important to be careful not to cut too much hair, as this can damage the hair and make it more prone to breakage.
