While we don’t have a definitive answer just yet, researchers are working to find out how much heat is too much before you lose your permanent curl pattern.
“The U.S. ethnic hair-care community in 2009 alone spent $9.5 billion on hair care and cosmetics, so there is a large market for this,” said Purdue’s Tahira Reid. “Though in wide use by both the general public and professional stylists, the lack of empirical research on very curly hair hinders effective use of heat. We are showing a unique approach for integrating customer needs, design methods and thermal sciences all at once.”
Their hope is that one day you would be able to refer to a diagram that says: “This is my hair-curl pattern. I can use my flat iron at this temperature this number of times per month and not have any damage.”
I’ll be keeping my eyes peeled for the final research paper and will let you know when it comes across my desk!
