A new study published in Dermatologic Surgery in April suggests platelet-rich plasma (PRP) has a positive effect on androgenetic alopecia (AGA).
The study, titled ‘Randomized Placebo-Controlled, Double-Blind, Half-Head Study to Assess the Efficacy of Platelet-Rich Plasma on the Treatment of Androgenetic Alopecia,’ involved a randomised, placebo-controlled, double-blinded study in 25 patients with AGA.
PRP was injected in one half of the head and the other half of the head was injected with placebo, with each patient receiving a total of three treatments of PRP at one month apart.
The results displayed improvement six months after the first treatment with PRP when compared to the placebo. Dr Rubina Alves, from the department of dermatology at the Universitat Internacional de Catalunya in Barcelona, Spain, and her colleagues concluded their study by reporting, “PRP was identified as having a beneficial effect in alopecia and has been postulated as new therapy for androgenic alopecia.”
Although the authors said the therapy produced promising results, they recommended further research. “This clinical research provides support that the application of [platelet-rich plasma] may have a therapeutic effect on [androgenetic alopecia] and can be used as a safe complementary treatment option. However, more controlled and well-designed clinical trials should be conducted to confirm the clinical improvement of [androgenetic alopecia] with administration of [platelet-rich plasma],” they said.
