April 2013 in “British Journal of Dermatology” 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.
88 citations
,
December 2012 in “Journal of The European Academy of Dermatology and Venereology” This study found that interfollicular injection of autologous CD34+ cell-containing PRP preparation improved hair count and thickness in patients with pattern hair loss, with better results than placental extract treatment.
270 citations
,
March 2012 in “Dermatologic Surgery” 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.
27 citations
,
March 2012 in “Dermatologic Surgery” This study found that finasteride treatment reduced caspase-1 expression, suggesting that androgens may influence immune processes in the hair cycle of androgenetic alopecia.
166 citations
,
August 2011 in “Dermatologic Surgery” This study found that PRP combined with dalteparin and protamine microparticles may enhance hair growth by increasing hair thickness compared to PRP alone.
81 citations
,
June 2010 in “Journal of Dermatological Treatment” 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.
51 citations
,
February 2009 in “Journal of dermatological science” In this study, β-catenin overexpression in human hair outer root sheath cells increased the expression of Pitx2, which activated the follicular differentiation pathway, suggesting Pitx2's potential role as a modulator in hair growth control.
41 citations
,
January 2007 in “Journal of Korean Medical Science” This study found that combining minoxidil with all-trans retinoic acid additively promoted hair growth in vitro by activating certain cell survival pathways and reducing apoptosis markers more effectively than minoxidil alone.
251 citations
,
October 2006 in “Plastic and reconstructive surgery/PSEF CD journals” 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.
149 citations
,
March 2004 in “Journal of Dermatological Science” This study found that minoxidil stimulates hair follicle growth by promoting dermal papilla cell survival and activating ERK and Akt pathways, which leads to increased proliferation and reduced cell death.
158 citations
,
May 2003 in “Journal of Investigative Dermatology” This study observed that hair follicle mesenchyme in mice exhibits significant plasticity during the hair cycle, with cell migration and changes in papilla size impacting hair production.
23 citations
,
January 2002 in “Journal of Cutaneous Medicine and Surgery” This study suggests that finasteride may affect hair follicle growth by altering the expression of caspases and XIAP, potentially regulating the anagen phase of hair growth.
105 citations
,
December 1998 in “Archives of Dermatological Research” This study found that dermal papilla cells in human hair follicles exhibit stronger expression of VEGF mRNA and protein compared to other follicular cells, suggesting their key role in angiogenic processes related to hair growth.
