Damaged hair scatters light,
leaving it dull

เมื่อผมต้องสัมผัสกับอุณหภูมิที่สุดขั้ว เส้นผมจะเกิดรูพรุนขึ้น เมื่อแสงกระทบกับรูพรุนดังกล่าว ก็จะมีการกระจายออกไปในทุกทิศทาง ซึ่งจะทำให้ประกายสะท้อนของผมลดลง ความเปล่งปลั่งเงางามของผมก็จะลดลง

A comparison of damaged hair's ability to reflect light with that of healthy hair

Hair that’s less damaged is better
at reflecting light, making it shine

The Dyson Supersonic™ hair dryer uses intelligent heat control to maintain Dyson’s optimum temperature, helping to prevent extreme heat damage. Less damaged hair reflects light in a single direction, making the hair appear shiny.
