Platelet-rich plasma by single spin process in male pattern androgenetic alopecia: Is it an effective treatment?

Androgenic alopecia (AGA) is a type of progressive hairloss, where there is androgen mediated conversion of susceptible terminal hairs into vellus hairs, in genetically predisposed individuals. To compare efficacy of Topical 5% Minoxidil alone versus Topical 5% Minoxidil with Autologous Platelet Rich Plasma (PRP) therapy in patients with Androgenetic Alopecia.This is aProspective study conducted in Department of Dermatology GMERS Medical College, Gandhinagar, Gujarat. A convenience sample of 62 men in the age group of 20-40 with Grade 2-5 AGA according to Hamilton- Norwood Grading were selected and was divided into 2 groups of 31 each. Presitting digital photographs and dermoscopic photos were taken. Autologous PRP was prepared using 18 ml of patients blood after double spin centrifugation and injected by Nappage technique. Results were assessed at the baseline and at the end of each sitting on the basis of change in hair density, photographic evaluation and patient’s self satisfaction. Highly significant increase in hair density was achieved after 4 months of treatment. At T4 (Fourth Session of treatment) Group B showed higher hair density (42.97± 8.96) as compared to Group A (36.94 ± 11.57) which was statistically significant at P = 0.03Group B showed better improvement as compared to Group A.PRP treatment has a positive therapeutic effect on male Androgenetic alopecia without major side effects.

Abstract Background Female pattern hair loss (FPHL) is the most common hair loss disorder in women. Platelet-rich plasma (PRP) provides an option for patients recalcitrant to the currently approved therapies. As there are many methods for the preparation of PRP, the most suitable for AGA therapy is not yet clear. Aims To compare the efficacy between single and double spin PRP injections in treatment of FPHL and to assess the relationship between the concentrations of vascular endothelial growth factor (VEGF) in the PRP preparation and the treatment results obtained. Patients and Methods 15 female patients with FPHL were enrolled. Each patient was subjected to intradermal injection of PRP (prepared by double-spin method) into the right half of the scalp, in addition to intradermal injection of PRP (prepared by singlespin method) into the left half of the scalp in the form of three treatment sessions three weeks apart. Evaluation of treatment response was done through comparing patients' global photographs, assessment of patients' satisfaction and folliscopic assessment before and after treatment. Results Our results showed clinically significant improvement by comparing patients' photographs in most of the treated patients. In addition, folliscopy revealed significant change of the terminal hair density in the right half of the scalp following treatment sessions.VEGF concentration didn't differ significantly between double-spin and single-spin prepared PRP, also it didn't differ significantly upon calcium activation. Conclusions PRP is an effective treatment modality for FPHL. Double-spin prepared PRP could yield better results in the treatment of FPHL than the single-spin method. However, adding Calcium gluconate prior to PRP injection is of no benefit as it didn't significantly increase the release of VEGF. Yet, further studies discussing different PRP preparation protocols and involving a larger number of cases are needed to minimize statistical errors and to detect the most accurate PRP preparation method with the greatest yield of growth factors.
