![]() The tubes were rotated in a centrifugation machine at 1500 revolutions per minute for 6 minutes. ![]() PRP was prepared by collecting 20 cc of fresh blood in sodium citrate containing vaccutainers in minor operation theatre under proper aseptic precaution. To evaluate overall hair growth, hair volume, hair quality and fullness, global pictures were taken in every session from front, vertex, lateral and back view. The hair was firmly tugged away from the scalp, and the extracted hair was counted in every session. A bundle of approximately 50-60 hair was grasped between the thumb, index and middle finger from the base close to the scalp. All patients were advised to avoid washing hair two days prior to the treatment. The aim our pilot study was to evaluate the safety, efficacy and feasibility of PRP for treatment of androgenic alopecia.īefore each session, the hair pull test was performed three times by the same clinician. ![]() It is hypothesised that growth factors released from platelets may act on stem cells in the bulge area of the follicles, stimulating the development of new follicles and promoting neovascularisation. Activation of alpha granules of platelets releases numerous proteins, including platelet-derived growth factor (PDGF), transforming growth factor (TGF), vascular endothelial growth factor (VEGF), insulin-like growth factor (IGF), epidermal growth factor (EGF) and interleukin (IL)-1. PRP has attracted attention in several medical fields because of its ability to promote wound healing. Although the optimal PRP platelet concentration is unclear, the current methods by which PRP is prepared report 300-700% enrichment, with platelet concentrations consequently increasing to more than 1,000,000 platelets/L. Platelet-rich plasma (PRP) is an autologous preparation of platelets in concentrated plasma. Androgenic alopecia or male pattern baldness is a very common type of hair loss observed in both males and females.
