WEBVTT NOTE This file was generated by Descript 00:00:01.770 --> 00:00:06.360 We estimate that over a third of people around the world have curly hair and 00:00:06.360 --> 00:00:09.150 this number will reach 40% by 2030. 00:00:11.670 --> 00:00:14.760 Along with that recognition is a growing body of research, looking 00:00:14.760 --> 00:00:18.270 at what makes curly hair unique, all the way down to the individual. 00:00:20.370 --> 00:00:23.370 Our scientific endeavors are part of an effort to redefine what 00:00:23.370 --> 00:00:26.760 historically has been a one size fits all approach to hair health. 00:00:27.510 --> 00:00:29.940 Our research not only broadens our understanding of. 00:00:30.000 --> 00:00:33.270 The different hair types, but reflects our commitment to inclusivity. 00:00:34.050 --> 00:00:37.380 The hair care industry can no longer assume what works for 00:00:37.380 --> 00:00:38.460 someone with straight hair. 00:00:38.670 --> 00:00:41.790 Also works for a person with textured, wavy, or curly hair. 00:00:48.300 --> 00:00:52.140 Our research involves better understanding the diversity within the curly hair 00:00:52.140 --> 00:00:57.330 spectrum, how people live, how people see and want to see their hair and 00:00:57.330 --> 00:00:58.860 their preferred styling routines. 00:01:01.920 --> 00:01:05.970 Researchers originally classified hair into a few broad geographic 00:01:05.970 --> 00:01:09.570 categories, but in an effort to diversify these categories. 00:01:09.630 --> 00:01:15.390 At L'Oreal, we studied the hair types of almost 2,500 people in 22 countries. 00:01:16.320 --> 00:01:20.610 We measured the diameter of curls, the curvature, the number 00:01:20.610 --> 00:01:22.530 of waves, and the tendrils. 00:01:24.539 --> 00:01:27.960 The result of this research was a classification system we call. 00:01:28.304 --> 00:01:29.085 The curl scale, 00:01:32.085 --> 00:01:35.295 we identified eight categories of curls across ethnicities. 00:01:35.685 --> 00:01:39.645 On one end of the scale, the hair has nearly no curvature to it, and on the 00:01:39.645 --> 00:01:41.925 other end, the curls are tightly coiled. 00:01:42.735 --> 00:01:46.545 Along with the incredible diversity of curly hair types, our vastly different 00:01:46.545 --> 00:01:52.155 biological processes, we've learned that sebum, the oil that is naturally produc 00:01:52.155 --> 00:01:56.085 in our scalp is extremely important for hydrating hair with curly texture. 00:01:56.740 --> 00:02:00.580 By looking at the rate at which sebum travels down each of these eight curl 00:02:00.580 --> 00:02:04.690 types, our researchers found that it moves more slowly to the end of a curl 00:02:04.690 --> 00:02:06.910 strand, the more cold the hair is. 00:02:08.259 --> 00:02:11.770 As a result, we have a better understanding of the importance 00:02:11.770 --> 00:02:15.760 of hydration practices like scalp cleansing for people with curly hair. 00:02:19.315 --> 00:02:23.125 Many women on the curlier end of the spectrum may not wash their hair as often 00:02:23.425 --> 00:02:25.135 leading to dandruff and itchy scalp. 00:02:25.585 --> 00:02:29.635 The symptoms are caused by a type of fungi mal easier, and our 00:02:29.635 --> 00:02:32.545 research has shown that weekly hair washing can help reduce it. 00:02:36.270 --> 00:02:39.840 And finally, there's been robust field research on the impact that 00:02:39.870 --> 00:02:44.070 environmental factors like humidity, UV light, and pollution can have on hair. 00:02:45.510 --> 00:02:49.350 A recent study found that hair exposed to extreme climate conditions in 00:02:49.470 --> 00:02:53.220 urban environments underwent the same type of cell damage associated 00:02:53.220 --> 00:02:55.440 with aging, the same process. 00:02:55.490 --> 00:02:57.620 That causes hair to go gray and brittle. 00:02:59.900 --> 00:03:01.910 All of this research is just a start. 00:03:02.960 --> 00:03:06.260 We recently partnered with Verily to launch the largest skin and hair 00:03:06.260 --> 00:03:11.360 health study tracking women aged 18 to 70 across social, economic and 00:03:11.360 --> 00:03:13.400 cultural backgrounds over several years. 00:03:14.420 --> 00:03:17.690 The goal is to learn even more about how environment. 00:03:17.755 --> 00:03:21.595 Lifestyle, hair care routines and age affects hair health. 00:03:22.585 --> 00:03:25.644 Our commitment to understanding and celebrating the diversity 00:03:25.644 --> 00:03:29.245 of hair worldwide isn't just about the science of curls or the 00:03:29.305 --> 00:03:30.894 impact of environmental factors. 00:03:31.435 --> 00:03:35.125 It's also about ensuring that our research reflects communities 00:03:35.125 --> 00:03:38.720 globally, especially those historically overlooked in dermatology. 00:03:40.495 --> 00:03:44.125 A testament to this commitment is a recent study we published earlier this year. 00:03:44.260 --> 00:03:47.320 Supporting dermatological research in Sub-Saharan Africa. 00:03:48.250 --> 00:03:52.060 This study underscores our efforts to advance local skin and hair research 00:03:52.179 --> 00:03:58.720 through the African Hair and Skin research grants program from 2013 to 2022. 00:03:59.200 --> 00:04:03.760 We've supported African researchers in exploring conditions, prevalent in 00:04:03.760 --> 00:04:08.170 skin and hair, in people of African ancestry, promoting better healthcare 00:04:08.260 --> 00:04:11.799 and empowering consumers with knowledge to avoid using inappropriate products. 00:04:14.630 --> 00:04:18.320 These initiatives not only contribute to a growing understanding of the unique 00:04:18.320 --> 00:04:22.940 characteristics of curly coly and textured hair, but also reinforce L'Oreal's 00:04:22.940 --> 00:04:28.340 dedication to inclusivity, ensuring that everyone everywhere has the knowledge 00:04:28.430 --> 00:04:29.960 and products tailored to their needs. 00:04:31.914 --> 00:04:35.750 It is about making a real positive impact in the communities We.
