September 2009 in “Journal of Ginseng Research” This study found that taking Korean red ginseng significantly increased hair density and thickness in patients with androgenic alopecia compared to a placebo over 24 weeks.
34 citations
,
April 2009 in “Skin Pharmacology and Physiology” This study found that Minoxidil had biphasic effects on normal human keratinocytes, stimulating proliferation at micromolar doses, but showing antiproliferative, pro-differentiative, and cytotoxic effects at millimolar concentrations.
22 citations
,
March 2009 in “Journal of Natural Medicines” This study found that Erica multiflora extract promotes hair growth by enhancing dermal papilla cell activity and shifting hair follicles from the telogen to the anagen phase in both in vitro and in vivo models.
19 citations
,
August 2008 in “Journal of The European Academy of Dermatology and Venereology” In this study, researchers observed that in advanced androgenetic alopecia, increased DNA damage in the frontal bald area may lead to cell apoptosis due to impaired repair capacity.
106 citations
,
June 2005 in “Journal of Investigative Dermatology” This study defines classification criteria for hair follicle dystrophy using a mouse model of chemotherapy-induced alopecia, providing tools for standardized hair damage assessment.
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.
59 citations
,
August 2003 in “Phytotherapy Research” This study found that a 70% methanol extract from red ginseng stimulated hair growth in mouse vibrissal follicles, suggesting its bioactive components, particularly certain ginsenosides, may promote hair growth.
174 citations
,
November 2002 in “Expert Reviews in Molecular Medicine” 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.
157 citations
,
July 2001 in “British Journal of Dermatology” In this study, the prevalence of androgenetic alopecia among Korean men and women was found to be lower than in caucasians, with Korean men showing more frontal hairline preservation and a higher incidence of 'female pattern' hair thinning.
231 citations
,
December 1999 in “Journal of Investigative Dermatology” This study found that the volume of a hair follicle's dermal papilla is strongly correlated with its size, primarily due to the number of cells it contains and the volume of extracellular matrix.
