How Hot Your Heat Tools Should Be Based on Your Hair Type

While there are plenty of hot tools that offer a range of heat settings that you can control based on your individual hair type (and we highly recommend you use them when you can), there are also emerging technologies on the market that do the hard part for you. Take the T3 Lucea ID Straightening and Styling Iron ($250), for example. Its smart-touch design lets you enter in your texture, length, and color treatment in the settings in order to calculate your perfect heat setting (of nine total) to minimize damage. Brilliant.
