January 1998 in “Journal of Endocrinology” This study found that dermal papilla cells from balding scalp hair follicles have significantly higher levels of androgen receptors than those from non-balding follicles, supporting their in vivo androgen response.
124 citations
,
April 1992 in “Journal of Endocrinology/Journal of endocrinology” This study observed that cells from androgen-sensitive areas like the beard and scrotum showed higher androgen receptor levels compared to those from non-balding scalp areas, supporting the role of dermal papilla in follicle growth responses to androgens.
November 2022 in “Journal of Investigative Dermatology” This study suggests that vellus to terminal hair follicle reconversion can occur in male pattern androgenetic alopecia using an in vivo model with minoxidil and platelet-rich plasma treatment.

March 1996 in “British Journal of Dermatology” This study found that dermal papilla cells from balding follicles exhibit distinct growth characteristics compared to non-balding cells, suggesting their potential as a model for understanding androgenetic alopecia.
October 2023 in “Acta dermato-venereologica” Minoxidil and platelet-rich plasma can help turn thin hair into thicker hair in male pattern baldness.
This study reported that paracrine factors, such as IGF-I and SCF, were reduced in balding hair follicles compared to non-balding ones, while inhibitory factors like TGFß-1 were increased, providing insights into the androgen action in hair follicles.

,
February 2007 in “Seminars in Cell & Developmental Biology” This review explores the hormonal regulation of hair growth and changes with season, age, and sexual development, and calls for improved treatments for hair disorders.
1 citations
,
September 2020 in “Journal of Dermatological Science” In this study, researchers found that the gene LRRC15 was overexpressed in dermal papilla cells from balding areas compared to non-balding areas in patients with androgenetic alopecia.
June 2024 in “Archives of Dermatological Research” In this study, significant upregulation of the genes SFRP2 and PTGDS was found in bald hair follicles of female pattern hair loss patients compared to non-bald follicles, suggesting these genes may be biomarkers and play a role in hair loss for this condition.
171 citations
,
July 2007 in “Journal of Investigative Dermatology” The researchers reported that DHT-inducible DKK-1 may play a significant role in DHT-driven balding by inhibiting hair follicle cell growth and promoting apoptosis in androgenetic alopecia.
28 citations
,
March 1973 in “The Journal of Clinical Endocrinology & Metabolism” This study found that hair follicles from balding men show significant metabolic differences compared to those from non-balding individuals, particularly in their ability to process dehydroepiandrosterone.
3 citations
,
May 2008 in “Hair transplant forum international” This document includes a brief professional profile of Dr. Ralf Paus but presents no research findings or study results.
66 citations
,
June 2010 in “Experimental Dermatology” This paper argues that the cycling hair follicle serves as a valuable model for systems biology research, highlighting its potential for translational medicine.
14 citations
,
April 2007 in “Journal of aging and health” This study observed that balding was associated with lower total body BMD in men and higher hip BMD in women, possibly due to estrogen use in the latter group.
4 citations
,
January 2017 in “Annals of Dermatology” Tianeptine may help prevent hair loss by promoting hair growth and reducing cell death.
This study found that isolated human scalp hair follicles express PGE2 genes and EP2 protein, suggesting PGE2 may play a crucial role in regulating hair growth.
April 2023 in “Journal of Investigative Dermatology” This study explores how chromatin differences between dermal papilla cells and papillary fibroblasts contribute to hair follicle inductivity and investigates the regulatory changes in androgenic alopecia.
This study found that neurotrophins produced by balding dermal papilla cells inhibited both their proliferation and hair follicle growth in vitro, suggesting a potential role in androgenetic alopecia.
34 citations
,
July 1993 in “The journal of investigative dermatology/Journal of investigative dermatology” This study suggests that androgens influence hair follicle behavior via the dermal papilla, using evidence from human and red deer cells with differing androgen responses as models.
