Damaged hair scatters light, leaving it dull
When hair is exposed to extreme temperatures, pores can begin to form within the strands. When light hits these pores, it scatters in all directions. This can reduce reflected light, decreasing shine.
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.
