QR 678 and QR678 Neo vs PRP—A Randomized, Comparative, Prospective Study

In this study, QR 678 and QR 678 Neo formulations containing growth factors and peptides were found to be safe in vitro and promoted hair growth in vivo in an animal model, suggesting their potential as treatments for alopecia, including secondary alopecia post-chemotherapy.

This review outlines recent research on platelet-rich plasma, alone or combined with other therapies, for managing hair loss disorders, and discusses future prospects without reporting new clinical findings.

In this study, researchers administered eight sessions of intradermal injections containing growth factors into the scalp of 1000 patients, reporting a significant reduction in hair fall in 83% of participants and increased total hair count and shaft diameter, with promising tolerance and safety.

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 assesses the use of platelet-rich plasma in dermatology and concludes that while there may be modest benefits for certain conditions, more evidence is needed before it can be widely recommended.

This review evaluates the therapeutic potential of platelet-rich plasma for treating non-cicatricial alopecias and suggests it may be effective, though further research is needed to confirm its efficacy.

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.

In this retrospective study, PRP injections for alopecia were found to improve hair volume and quality, with high patient satisfaction, particularly in those with less than 2 years of hair loss.

This review discusses recent advancements in hair rejuvenation strategies and assesses the potential of herbal drugs as safer alternatives, but reports no new clinical results.

This abstract describes the components found in the alpha and dense granules of platelets, but it provides no new research findings.

In this study, genetic variation in the CYP19A1 gene, particularly the common rs4646 C allele, was associated with an increased risk of female pattern hair loss, especially in women under 40.

This review discusses the advantages and limitations of various hair loss evaluation methods but reports no new results; it emphasizes the importance of cautious interpretation for these diagnostic tools.

This review discusses the various treatment options for male and female pattern hair loss and provides no new clinical results; the authors outline the most effective strategies based on existing evidence.

In this study, platelet plasma growth factors from patients' autologous plasma improved follicular unit yield in baldness surgery by 15.1% compared to control areas.

This review discusses the genetic factors contributing to androgenetic alopecia and highlights the potential for developing more effective therapies based on recent discoveries, but reports no new clinical results.

Hair loss in women is common, starts in late 20s, and affects 30% of women over 50.

This case report describes a young woman with hypopituitarism who experienced hair loss typical of female androgenetic alopecia without detectable androgens, suggesting this hair loss pattern may not always be androgen dependent.

In male pattern hair loss, this study found that finasteride 1 mg daily significantly slowed hair loss and increased hair growth over two years compared to placebo.

This study found that epidermal and fibroblast growth factors increased proliferation of human hair bulb papilla cells and root sheath fibroblasts in vitro, while hydrocortisone decreased it and minoxidil had no effect.

Minoxidil promotes hair growth in male pattern baldness.
