Platelet-Rich Plasma as a Treatment for Androgenetic Alopecia

In this study, subdermal platelet-rich plasma injections significantly increased hair count and shaft caliber in individuals with androgenetic alopecia, with monthly treatments potentially offering greater benefits.

This study found that platelet-rich plasma injections improved hair density and diameter in women with androgenetic alopecia not responding to other treatments over 24 weeks, with no adverse events reported.

This study found that a single injection of platelet-rich stroma significantly increased hair density in men with androgenetic alopecia within 6 to 12 weeks, with no reported side effects.

In this study, 23 patients with androgenetic alopecia were treated with non-activated autologous platelet-rich plasma (A-PRP) administered through interfollicular injections, but the abstract provides no results of the treatment's effectiveness.

This study found that platelet lysate produced higher follicular regeneration in hair restoration surgeries compared to activated PRP and saline, with significant gains in both follicular unit and hair density.

In this study, researchers found that homologous PRP (h-PRP) significantly increased hair density more than both nonactivated (n-PRP) and activated (a-PRP) autologous PRP in patients with androgenetic alopecia, suggesting h-PRP as a potentially more effective treatment option for hair loss.

This article discusses the use of platelet-rich plasma as a supportive treatment for hair loss, emphasizing its potential to enhance hair follicle health and patient satisfaction, but reports no new clinical results.

This review suggests that PRP injections may be effective in promoting hair regrowth, reducing hair loss, and increasing hair thickness in patients with androgenic 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 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.

This study observed that autologous platelet-rich plasma treatment improved hair count and density in areas with androgenetic alopecia compared to placebo, with differing outcomes based on the PRP collection device used.

This study found no significant benefit from PRP injections for treating androgenetic alopecia in men, highlighting the need for larger, well-designed trials to assess its effectiveness and safety.

This study found that a standardized PRP application protocol was effective as a coadjuvant therapy in most patients with androgenetic alopecia who did not respond to minoxidil or finasteride, based on improvements in Ebling's scale.

This study found that PRP injections improved hair density, quality, and thickness in males with androgenic alopecia compared to placebo, with reported high patient satisfaction and no major side effects.

This study found that platelet-rich plasma was more effective for treating alopecia areata than topical 5% minoxidil, leading to earlier hair regrowth and reduction in hair abnormalities.

Platelet-rich plasma treatment significantly increased hair diameter and density, stopped hair fall, and boosted hair growth in men with hair loss, with no reported side effects.

This study found that platelet-rich plasma was not effective in treating androgenetic alopecia in men with grade 4–6 hair loss.

This analysis suggests that platelet-rich plasma therapy may be promising for treating androgenetic alopecia, but further controlled trials with standardized measures are needed to confirm its efficacy.

This study found that intra-operative platelet-rich plasma therapy may enhance hair regrowth, increase graft density, and activate dormant follicles more effectively than normal saline in follicular unit extraction hair transplant patients.

This study found that platelet-rich plasma injections significantly increased hair count and density in patients with male pattern hair loss without major side effects, suggesting it may be a safe and effective treatment option.

This study found that platelet-rich plasma injections led to improvements in hair counts, thickness, and strength in patients with androgenic alopecia, showing promise as an effective treatment with no major adverse effects.

This study reported that AA-PRP injections significantly increased hair count and density in individuals with pattern hair loss compared to baseline, demonstrating their potential for enhancing hair growth.

This review discusses the use of platelet-rich plasma in various dermatological applications and reports no new clinical results; the authors call for more rigorous trials to confirm its effectiveness.

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 study found that PRP injections may improve hair density and reduce hair loss in patients with androgenetic alopecia without significant side effects, but further research is needed to confirm efficacy.

In this study, platelet-rich plasma significantly increased hair regrowth and reduced symptoms of alopecia areata compared to triamcinolone acetonide or placebo, with no observed side effects.

Alopecia Areata is an autoimmune condition causing hair loss with no cure and treatments that often don't work well.

This study found that autologous platelet-rich plasma increased hair growth potential by enhancing dermal papilla cell proliferation and stimulating key signaling pathways in both cell cultures and mice models.

This study identified TGF-β2 as a crucial signal in hair follicle stem cell regeneration, highlighting its role in counteracting BMP signaling to promote tissue regeneration.

This study found that PRP combined with dalteparin and protamine microparticles may enhance hair growth by increasing hair thickness compared to PRP alone.

This study found that the BMP antagonist noggin induces hair growth in postnatal skin by neutralizing BMP4's inhibitory activity, potentially mediated by changes in Shh expression.

This study found that VEGF significantly enhances perifollicular vascularization during the hair growth phase, accelerating hair regrowth and increasing follicle and hair size, while its inhibition retards hair growth.
