Non-scarring hair loss
Patients seen at Northwestern Memorial Hospital or Northwestern Medical Faculty Foundation physician offices that have undergone evaluation for hair loss and have a diagnosis of androgenetic alopecia, telogen effluvium or alopecia areata.
Age-matched controls who do not have a history of hair loss and have normal scalp skin without evidence of hair loss.
- PAI-1 expression level in scalp skin biopsy samples [ Time Frame: Baseline ]Tissue PAI-1 expression levels will be determined by immunohistochemistry, a three-layer biotin-strepavidin system. Positive PAI-1 expression per total tissue area will be quantified using the color-picker function in imaging software.The PAI-1 expression found in normal scalps will be compared to those found in scalps with hair loss.
