Therapeutic efficacy of TriCell CD34⁺ cell-containing, platelet-rich plasma in alopecia patients

Platelet-rich plasma (PRP) containing various growth factors and stem cells can play a role in tissue regeneration. Recently, treatments such as CD34 + cell-containing PRP has been used in various fields, including that of hair loss. The aim of this study was to evaluate the efficacy of CD34 + cell-containing PRP injections for the treatment of alopecia. We extracted PRP from the blood of 10 patients using the TriCell Platelet Concentrate System (REV-MED Technologies Corp.). TriCell CD34 + cell-containing PRP preparations were injected onto the scalps of 5 patients with androgenetic alopecia including 2 female patients with pattern hair loss and 3 patients with alopecia areata. There were no special side effects, and overall, hair thickness and density were improved. Three months of TriCell CD34 + cell-containing PRP therapy (at 4-week intervals) resulted in improved hair thickness and density in alopecia patients.
