Summary:
This study attempted to stimulate hair growth in males using a treatment called platelet-rich plasma (PRP) to help with hair regrowth. Inconstancies in the application of this treatment lead them to test two ways of applying the PRP: one using a special device called a dermapen (GrowPro's system) and the other by injecting it manually (traditional method). They found that both methods improved hair count and thickness, but the dermapen method was found to be superior at delivering the application. The dermapen performed significantly better in terms of anagen, telogen, and average hair length parameters.
