In 2020, T3 debuted its Luceia ID, a straightener with a smart-sensor interface that allows you to punch in information about hair texture, type, length, and degree of colour treatment, ensuring you are given a heat setting calculated for you based on your individual hair type. In 2021, T3 applied that same technology to T3 Curl ID (£289), a 1.25" curling iron with a clamp and ceramic barrel that promises shiny, soft, long-lasting curls without totally ruining your hair. And whilst not part of the splashy new technology, we have to say we also appreciate the addition of a cool-touch tip, which keeps you from burning your fingers off as you style your hair.
