Abstract
BACKGROUND
Stromal vascular fraction (SVF) cells derived from adipose tissue and platelet-rich plasma (PRP) are among novel treatments for androgenetic alopecia (AGA). We aimed to investigate the effect of adding SVF to PRP and compare it to administering PRP injection alone.
METHODS
Eighteen patients were randomly divided into two groups of nine. The PRP group was treated with PRP at all three visits at 1-month intervals, while the SVF-PRP group received an SVF injection on the first visit and a PRP injection on the second and third visits. Each group was evaluated at baseline and 20 weeks after the therapy's initiation.
RESULTS
Changes in mean hair diameter and hair count compared to baseline were significant in both groups. The PRP group experienced a greater increase in mean hair count than the SVF-PRP group, and the SVF-PRP group had a marginally greater increase in hair diameter than the PRP group. These differences were not statistically significant compared to each other. The patient and physician assessment scores exceeded the mean (on a scale from 0: poor to 3: excellent) in both groups.
CONCLUSION
Adding one SVF injection to two PRP treatment sessions versus three PRP injections alone had no significant difference in evaluated variables. If additional research demonstrates the same results, we suggest that multiple SVF injection sessions may be required to produce a statistically significant difference compared to PRP injection alone. Moreover, considering lower cost and greater accessibility of PRP, it can be used before SVF in the treatment of AGA.
