Comparing Single-Spin Versus Double-Spin Platelet-Rich Plasma Centrifugation Methods on Thrombocyte Count and Clinical Improvement of Androgenetic Alopecia: A Preliminary, Randomized, Double-Blind Clinical Trial

The study compared single-spin and double-spin platelet-rich plasma (PRP) preparation methods in treating androgenetic alopecia (AGA) in 30 male subjects aged 25 to 59 years. Both methods significantly increased thrombocyte counts by 4 to 5 times from their initial levels, with the single-spin group showing a more significant increase. Both groups also showed significant improvements in hair density, hair rate, and hair count of anagen, telogen, vellus, and terminal hair. The study concluded that both PRP preparation methods have tremendous therapeutic promise for treating AGA, and clinicians may choose either technique.
