Heat styling tools are devices used to shape and style hair using heat. Common examples include hair straighteners, curling irons, and blow dryers. These tools work by applying heat to the hair, which alters its structure temporarily, allowing for various styles such as straight, wavy, or curly. While heat styling can create beautiful looks, it can also damage hair if used excessively or without proper protection. To minimize damage, it's advisable to use a heat protectant spray and to choose tools with adjustable temperature settings. Regular conditioning treatments can also help maintain hair health.
