Hair care experts and reviewers discuss heat styling and technology

Hair styling tools such as straighteners and dryers can transform hair texture, but excessive use or high temperatures can weaken the hair shaft. Because hair is nonliving tissue once grown past the scalp, it cannot biologically repair structural damage like split ends. The American Academy of Dermatology recommends using flat irons on dry hair at low or medium heat and limiting frequency of use to prevent dryness, roughness, and fraying.

In the consumer technology space, new AI-powered tools like the Dreame Aero Straight Pro are entering the market as alternatives to established brands. These devices utilize NTC sensors to monitor temperatures hundreds of times per second to mitigate heat damage. Some models also feature app compatibility, allowing an AI assistant to analyze hair type and moisture levels to adjust settings automatically.
