Alopecia areata (AA). Hair growth response to different concentrations of intralesional triamcinolone acetonide (TA). A 3- × 3-cm patch of AA was divided into quadrants with tattoo marks for reference. Each quadrant was randomly assigned 2.5, 5, or 10 mg/mL TA or normal saline (NS) control. Each quadrant received the same TA concentration for 6 intralesional injections at 6-week intervals. The patches were photographed pretreatment (A) and at 42 weeks, after 6 treatment sessions (B). Hair growth responses in terms of density (P < .025) and caliber (P < .04) were observed in scalp skin receiving 2.5, 5, or 10 mg/mL TA, relative to NS control. Among the triamcinolone-injected quadrants there was no significant difference in the 5- and 10-mg/mL concentrations compared with the 2.5-mg/mL concentration.

Hair density (HD) response to different concentrations of intralesional triamcinolone acetonide (TA) for alopecia areata (AA). For each patient (N = 4), 2.5, 5, or 10 mg/mL TA in normal saline (NS) or NS placebo was injected into randomly assigned quadrants of AA patches on visit 1 and subsequent visits 2 to 6. HD was normalized by same-subject measurements from non-AA-affected scalp areas at visit 1. Change in HD was assessed at subsequent visits 2 through 7, and the changes in mean HD for each concentration are shown. Significant increase in HD (P < .025) over time was observed with 2.5, 5, or 10 mg/mL TA, but not with NS. However, there was no significant difference in the 5- and 10-mg/mL treated quadrants compared with the 2.5-mg/mL treated quadrant.
