In this study, PRP injections increased hair count and reduced hair loss in patients with androgenic alopecia not responding to minoxidil and finasteride, with high patient satisfaction reported.

This pilot study suggests injecting platelet-derived growth factors into the scalp may offer some clinical benefits for androgenetic alopecia, though further randomized trials are needed for confirmation.

This study found that adding platelet-rich plasma to microneedling improved outcomes for atrophic acne scars more than microneedling alone, according to both quantitative and qualitative assessments.

This study reports that plasma rich in growth factors appeared to improve hair follicle regeneration and patient satisfaction in individuals with androgenetic alopecia, though further trials are needed.

In this study using a mouse model, the researchers found that platelet-rich plasma significantly increased the number of newly formed hair follicles and decreased the time for hair formation compared to no treatment.

This study found that micro-needling with cosmeceuticals or platelet-rich plasma significantly improved wrinkles, skin laxity, scar softening, and hair growth over 12 months, with minimal side effects, and that the best results occur with pigment and platelet massaging between 5 to 30 minutes post-treatment.

In this study, patients with mild to moderate androgenetic alopecia who received platelet-rich plasma injections with microneedling showed improvements in hair growth and thickness, as well as high satisfaction, over a three-month period compared to conventional therapy non-responders.

This study found that older men with vertex balding had lower levels of IGFBP-3 and higher levels of IGF-1 in their plasma.

This study found that allogeneic platelet gel significantly improved healing in non-healing chronic lower leg ulcers compared to hydrogel treatment.

This study concluded that platelet-rich plasma injections significantly improved hair density, thickness, and scalp inflammation in both male and female pattern hair loss, with better outcomes in lower-grade cases.

In this study, iL-PRF injections produced significantly better clinical scores for androgenetic alopecia patients compared to controls, especially in those with more severe baseline conditions.

This review discusses platelet-rich plasma and microneedling for alopecia areata, reporting promising small-scale findings but no new results, and suggests further trials to determine efficacy and specific disease subtype suitability.

In this study, researchers aimed to investigate the effects of injecting intralesional platelet-rich plasma and vitamin D in patients with vitiligo, focusing on their potential to induce skin pigmentation. Results are not reported in the abstract.

This retrospective study found that treatment with autologous plasma rich in growth factors increased hair density and improved hair follicle health in patients with androgenetic alopecia, with no reported adverse effects.

This study found that the rs2228570 polymorphism of the VDR gene was associated with an increased risk of melanoma, while the rs731236 polymorphism was linked to a protective effect against the disease in Colombian patients.

This study found that platelet-rich plasma can transiently inhibit bacterial growth in vitro against multidrug-resistant strains from diabetic foot infections, although its efficacy diminished over time and did not affect biofilm formation.

This study found that older men with vertex balding have lower circulating levels of the protein IGFBP-3 and higher levels of IGF-1.

This case series observed that the combination of platelet-rich plasma and fat grafting improved hair quality and density in patients with non-scarring alopecia, with effects visible by 12 weeks and sustained up to one year.

This study suggests the mechanical effect of injecting a solution is more important than the solution's nature in treating atrophic acne scars, with UBM sonography proposed for objective assessment.

This randomized prospective study found that microneedling combined with autologous platelet-rich plasma resulted in significant hair regrowth and reduction in SALT score after 12 weeks in patients with chronic and stable alopecia areata, suggesting it as a safe and efficient treatment option.

This study found that prophylactic administration of autologous platelet-rich plasma during cesarean wound closure significantly improved wound quality and reduced the incidence of surgical site infections.

The study introduced an advanced skin model, ImmuSkin-MT, which effectively distinguished between different strengths of skin sensitizers by mimicking the interaction of immune cells in skin tissue.

In this study, PRP treatment improved hair loss in 40 female patients with female pattern alopecia, with most progressing to better grades of hair coverage after 6 months, while only minor pain was occasionally reported as an adverse effect.

This study found that direct interactions between human dermal papilla cells and melanocytes under low oxygen conditions improved cell functions and could be important for hair regeneration efforts.

This study found that fetal canine hair follicle-derived stem cells exhibited pluripotency markers, suggesting potential for therapeutic applications in hair and skin repair.

In this observational study, the combination of PRP and 5% minoxidil was more effective than minoxidil alone in promoting hair growth in men with androgenetic alopecia.

This study found that platelet-rich plasma injections significantly improved hair density, thickness, and patient satisfaction in women with female pattern hair loss compared to a placebo.

This review discusses the use of platelet-rich plasma as a treatment for androgenetic alopecia and highlights the need for standardized protocols, reporting no new clinical results.

This study found that combining herbal extracts with PRP increased human dermal papilla cell proliferation via ERK and Akt protein regulation, suggesting its potential for developing hair growth therapies.

In this study, the authors reported that among patients with androgenetic alopecia, treatment with minoxidil 5% lotion combined with PRP and microneedling resulted in better hair growth and higher satisfaction compared to other treatment groups.
