The Braun Satin Hair 7 ST780 hair straightener enables long-lasting styling results and healthy-looking, shiny hair. With its SensoCare technology, it detects the moisture content of each strand of hair and automatically adjusts the temperature from root to tip - for ultimate heat protection. The NanoGlide ceramic plates of the Satin Hair 7 ST780 glide three times more gently over the hair than conventional plates, and the movability of the plates provides even pressure distribution to avoid hair damage.
