Meaning ❉ Historical Dermatology Disparities illuminates the patterns of unequal dermatological attention and scientific understanding that have, over time, affected individuals with Black and mixed-race textured hair. This reality stems from systemic biases and historical oversights within medical education and research. For textured hair understanding, this meant a slower growth of precise knowledge concerning its unique characteristics and needs, creating gaps in how hair growth cycles and scalp wellness were perceived for diverse hair types. Regarding hair care systematization, it indicates the absence of standardized, effective care principles and routines truly suited for these distinct hair types, often leading individuals to thoughtfully develop their own structured ‘automation-like’ routines without adequate expert guidance. Practical application of knowledge was frequently hampered, as individuals encountered misdiagnosis, less effective treatments, or a lack of culturally attuned care from practitioners. This historical backdrop shapes our present approach to hair health, emphasizing the importance of informed, equitable practices for all hair types.
