A blow dryer is an electromechanical device that blows ambient or hot air over damp hair to speed up the evaporation of water and dry the strands, allowing for styling. It works by accelerating and controlling the formation of temporary hydrogen bonds within each strand, thereby providing strength for shaping and style. Blow dryers also help to close the hair cuticles, which reduces the likelihood of getting split ends.
Blow dryers come with a variety of attachments that can help to achieve various looks, such as volumizing fine hair, straightening curly hair, or creating voluminous beachy waves. They can even help to tame frizz and flyaways, and the heat from blow dryers can be used to get rid of tangles.
However, prolonged use of blow dryers can cause damage to your strands, which can lead to breakage, and in some cases, even hair loss. Additionally, prolonged exposure to high levels of heat from blow dryers can dry out the scalp, resulting in itchy and flaky conditions like dandruff.
Fortunately, there are ways to limit the damage caused by using blow dryers, such as avoiding overusing them or using them on the highest settings, and always applying a protective heat protectant before drying your locks. Investing in a high-quality hair dryer with ceramic or tourmaline technology is also helpful, as these materials distribute heat evenly. You can also try a heat-protection serum, such as the Bumble and bumble Invisible Oil Heat & UV Protective Primer, which not only provides heat protection but moisturizes your strands, detangles, and cuts down frizz. blow dryers
