African Hair Morphology: Macrostructure to Ultrastructure

The document "African hair morphology: macrostructure to ultrastructure" by Nonhlanhla P. Khumalo, published in the International Journal of Dermatology, explored the unique structural characteristics of African hair. The study utilized light and scanning electron microscopy to analyze the macrostructure and ultrastructure of African hair, revealing its distinct properties compared to other ethnic groups. The research highlighted that African hair tends to be more fragile, which is not related to the distribution of cystine-rich proteins. This fragility was attributed to the hair's unique shape and internal structure, contributing to its specific physical and chemical properties.
