Hair samples from all over the world were collected, examined, and then compared for the curl degree among different hair origins and ethnic groups.Īs time progressed, multiple studies have been published and the focus has been to figure out the structural reasons for curly hairs. They developed a method to measure the curve diameter of the curl. The author published his findings in Human Biology and International Journal of Dermatology in 2007. In 2003, French scientists, led by Geneviève Loussouarn, first described a classification technique for human hair.

Later in the 2000s, a series of papers were published in prominent dermatological and cosmetic science journals describing the latest efforts to explore the reasons for curliness. The paper discussed the biological aspects of the hair follicles and the chemical processing inside hair follicles that lead to different curl patterns. To the best of their effort, the first research report was published in 2003 titled “Hair shape of curly hair” in the Journal of the American Academy of Dermatology.
No attempt had been made to thoroughly examine the curl pattern and broaden the scope of the study. Later, research papers isolated the distinctions among ethnic hair fibers, mainly highlighting the hair diameter, mechanical strength, breakage, and amino acid analysis to determine the chemical nature of Caucasian and Afro hair. In the early days, fundamental physical and chemical analysis was the only tool to examine a hair fiber, and the focus had only been on European Caucasian hair. Historical background of curly hair types Let’s look at some historical views and science behind curly hair and answer the questions as to why some of us have curly hair and why curly hair looks and behaves differently. Over the previous two decades, hair scientists have studied why curly hair behaves differently from other types of hair and what causes it to do so. The curly nature of human hair has been a topic of great interest to hair experts and customers in recent years.
In recent years, hairs have been classified/divided into curl categories or degrees of curliness based on the extent of curliness. They vary in terms of their curl pattern and curl type, particularly when it comes to appearance. The physical characteristics of human hair vary considerably among different racial groups.Ĭaucasian, European, Afro, African-American, Latin, and Asian hair are the most commonly known groups of hair types characterized based on their different hair features.Ĭurly hair types differ depending on hair diameter, curliness, mechanical strength, color, and even hair density. There are many curl types, and each has a unique behavior structurally. The Science Behind Curly Hair Types and How it Behaves Structurally Especially for those who have dense strands or straw-strung coils, understanding your hair is essential to a successful regimen. If you’re following the standard hair types 1 through 4 with subcategories of A to C, you can discover your curly hair type and see which products will work best.
