TLDR Normal scalp and hair characteristics in Black Africans include white dots and a honeycomb pattern.
A study of 307 individuals in Lagos, Nigeria, examined the trichoscopic features of disease-free scalp and hair in Black Africans, finding that 31.3% had normal hair. The study included a nearly equal male-to-female ratio and participants primarily aged 35-39 years and under 25 years. Common features observed were white dots (99%), regularly distributed white dots (96.9%), and a preserved honeycomb pattern (95.8%), with peripilar casts in 14.6% of participants. These results establish a baseline for normal scalp and hair characteristics in Black Africans, useful for comparison in diseased states.
