Traction alopecia is a protracted form of hair loss resulting from persistent tension on the hair follicle . We report a case of a 9-year-old African American girl who presented with extensive scalp ulceration and alopecia 11 days after placement of a synthetic hair braid. Over a period of months, with consistent wound care and low-tension hairstyling, most of the hair regrew. We propose that the ulceration and hair loss in this case represents an acute variant of traction alopecia due to pressure-induced ischemia and necrosis.
牵引性脱发是一种因毛囊持续受张力而导致的慢性脱发形式。我们报告一例9岁非裔美国女孩的病例,该女孩在编织合成发辫11天后出现广泛的头皮溃疡和脱发。经过数月的持续伤口护理和低张力发型处理,大部分头发重新生长。我们认为,该病例中的溃疡和脱发代表了由压力诱导的缺血和坏死导致的牵引性脱发的一种急性变体。
