The presence of yellow dots seems to be a specific feature of alopecia areata and has been reported to be present in 95% of patients, regardless of their disease stages. Following histopathological correlation, these yellow dots represent degenerated follicular keratinocytes and sebum contained within the ostium of hair follicles. Although occasionally seen in advanced male-pattern hair loss, yellow dots are not seen in cases of female-pattern hair loss, scaring alopecia, or telogen effluvium.
