The hair you have can be straight or curled, crimped or coiled. You may be happy with it just the way it is, or you may be always trying to find new ways to style it. Well, the science of curls is being taken rather seriously at the Purdue University by a bunch of scientific researchers.

They are studying how the interplay of gravity, texture of the hair and the follicle that it grows out of, can all contribute to the actual manner in which the hair grows. They are also looking at symmetrical and asymmetrical follicles to see why the former grows straight hair and the latter curled.

Studying hair with computers in labs may seem like overkill, but each science project has its own importance and use. Currently the researchers are tying to figure out how the curly hair is made more vulnerable to heat during visits to the hair dresser.

Since straight hair conducts heat better it is less prone to burning than those curls. Now the team of researchers at Purdue University is conducting a science project to protect those curls by finding the optimum heat for styling them without causing them permanent damage. That’s knowledge that the curls on my hair could do with too.
