How Hot is Too Hot?

Usually when you get a new styling tool for your hair, like a curling iron or hair dryer, you want to crank it up to the highest, hottest setting—because if it’s not set on high, it’s not going to work, right? Wrong! Newer heat tools, like flat irons, offer adjustable settings, making it possible for users to turn up the heat to 450 degrees.

People, that is hot. That kind of heat is only meant for thick, dense, coarse strands. If you have fine hair, that dial should not move past 300 degrees. You risk severely drying and damaging your hair if you apply 400-plus degrees of heat on thinner locks. So please, always spritz a thermal protector onto hair, like Arrojo Thermal Protector ($14), and style safely.
