August 2012 in “Clinical and Experimental Dermatology” This study concluded that a 3% IGF-1 liposomal gel improved hair thickness and growth in hamsters without inducing significant hepatotoxicity or myelotoxicity, suggesting its potential as a safe hair-loss 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.
72 citations
,
January 2012 in “Annals of Dermatology” In this study, IGF-I was shown to enhance human hair follicle growth, maintain the anagen phase, and increase expression of certain growth factors and anti-apoptotic markers.
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.
314 citations
,
April 2010 in “Developmental Cell” This study found that in mice, inactivating beta-catenin in the dermal papilla reduces hair follicle progenitor proliferation and disrupts the hair cycle.
66 citations
,
February 2007 in “The journal of investigative dermatology/Journal of investigative dermatology” The researchers reported that adenosine increases FGF-7 expression in dermal papilla cells, which may stimulate hair growth via the A2b adenosine receptor and cAMP pathway.
43 citations
,
July 2005 in “Journal of Chromatography B” This study developed a sensitive method to precisely determine hair lipid composition, demonstrating specific lipid changes from the root to the tip in untreated hair fibers from two women.
162 citations
,
August 2004 in “Journal of Investigative Dermatology” This study suggests that stress negatively affects hair growth by inducing inflammation and early hair cycle transitions in mice, which might inform strategies for managing stress-related hair loss in humans.
55 citations
,
September 2003 in “Experimental Dermatology” In this study, researchers found that certain cytokines can significantly down-regulate PDGF expression in dermal papilla cells and follicular keratinocytes, indicating a potential link between PDGF signaling and catagen induction.
77 citations
,
February 2001 in “Journal of Dermatological Science” HGF activator helps convert HGF to its active form, promoting hair growth.
