Yes! PRP hair treatment is an effective procedure for hair loss and hair growth. Below we will discuss some of the research articles discussing PRP treatment for hair loss and PRP hair treatment success rate.
In 2019, a team of researchers did a systematic review of the medical literature on PRP as a treatment for hair rejuvenation. Their findings were published in the journal Aesthetic Plastic Surgery. Most of the studies found that injections of PRP reduced hair loss, increased the diameter of individual hairs, and increased the density of hair growth.
Also in 2019, another systematic review published in Dermatologic Surgery, reported that PRP treatments led to hair growth in both male and female patients.
Researchers in dermatology found evidence that PRP for hair loss can lead to hair regrowth. However, due to the limitations of these studies – small sample size, variation in technique and protocol among physicians, and unknown optimal platelet concentration – further research may be necessary to confirm the overall effectiveness of PRP injections.
A systemic review study published in dermatologic therapy in 2020 evaluated the efficacy of PRP in the treatment of female pattern hair loss and androgenetic alopecia. It comprised of 92 patients from 6 randomized controlled clinical trials and showed that PRP had a positive effect on female pattern hair loss with an increase in hair thickness and hair density. [1]
A meta-analysis study published in cosmetic dermatology in 2017 evaluated six studies (four studies were randomized controlled trials, while the other two were retrospective studies). It involved 177 patients and revealed a significant increase in number of hairs per cm2 after PRP injections compared to control and an increase in number of hairs and the percentage of hair thickness. [2]
Two other meta-analysis studies were performed that also had good outcomes for hair growth. They also revealed a significantly increased hair numbers per cm2 after PRP injections in the treatment group versus the control group with MD 38.75, 95% CI 22.22–55.28, P <0.00001 and MD 30.35, 95% CI 1.77–58.93, P <0.00001, respectively.[3][4]
Does PRP Hair restoration help with female pattern hair loss?
Yes! There is a lot of research that shows the effectiveness of this novel therapy in the treatment of hair loss in women. A review study published in dermatological therapy in 2020 evaluated the effectiveness of PRP in the treatment of female pattern hair loss and found very promising results. It comprised of 92 patients from 6 randomized controlled clinical trials and revealed that platelet rich plasma had a significant effect on female pattern hair loss and increased hair thickness and hair density in all participant. [6]
Two recent meta-analysis studies also confirmed the effectiveness of platelet rich plasma for female pattern hair loss. The first study consisted of 776 females with hair loss covering 16 randomized controlled trials and 26 observational trials. It showed that PRP has a good therapeutic effect on female pattern hair loss and improved hair density and hair count compared to the control groups. [7]
The second study from 8 clinical studies and a total of 197 females also showed a significant increase in hair count and hair diameter in 4 studies after PRP treatment. Patients who also underwent PRP hair restoration therapy had a high level of satisfaction and improvement in their quality of life. [8]
