Some people who have naturally curly hair (1)   to have it straightened.

Others with straight hair want to have curls.

   ?°It is kind of like the way I see the world, like the (2) through which I see the world and I always was wondering about how we can think about this from a mechanical engineering    (3) ," explains Tahira Reid, assistant professor of Mechanical Engineering at Purdue University.

   Hair irons can take many shapes but are (4) clips or rods with heated    (5) .

   ?°If you go to the mall right now you see an aisle full of straightening irons, and they have terms like ion technology and twirling," notes Amy Marconnet, also an Assistant Professor of Mechanical Engineering at Purdue University.

   The heat    (6)   or breaks a protein called keratin, responsible for the hair??s shape, and temporarily changes it. But nobody knows exactly at what level the heat can actually cause permanent damage.

?°If we understand the onset at which that happens than we might be able to    (7) before or give some suggestions before you get to that point," Reid says.

Inside a Purdue University lab, a    (8)   flat hair iron goes over a hair strand while an infrared microscope measures the changes in the hair??s structure.

Researchers say early results are a bit    (9) . It turns out that everyone??s hair is different and that there's no exact temperature where hair straightening becomes hair damage. For example, people with naturally curly hair can suffer more damage from heat irons than those with straight hair.

Reid says they will continue their research    (10)   finding that heat sweet spot for stylists.
