March 2017 in “Experimental Dermatology” In this exploratory study, researchers found slightly increased levels of inflammatory markers in scalp skin affected by androgenetic alopecia, suggesting differential gene expression involved in hair cycle and keratin production.
January 2012 in “Chinese Journal of Aesthetic Medicine” This study found that in hair follicles, androgen receptor expression is stronger in the hair loss and transitional areas compared to the occipital region, suggesting a role in male pattern baldness.

January 2010 in “Springer eBooks” January 2007 in “Zhongguo linchuang yixue” In this study, researchers observed that Keratin 15 expression in hair follicles was significantly higher in normal adult men compared to those with androgenetic alopecia.
4 citations

August 2005 in “Archives of Dermatological Research” This study detected higher expression of p63 in occipital scalp areas compared to frontal areas, with minimal changes in beta-catenin expression and a novel finding of CD34 positive cells in hair follicles' outer root sheath.
17 citations
,
December 2004 in “The Journal of Men's Health & Gender” This article discusses the role of androgens in hair follicle changes, explaining how dihydrotestosterone contributes to hair thinning on the scalp, while promoting thicker facial hair in men, and reports no new clinical results.

August 1999 in “Archives of dermatology” Hair follicles grow hair and release it through the skin.

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.
This narrative review discusses the hormonal control of hair growth, particularly focusing on dihydrotestosterone and its role in the pilosebaceous unit and androgen-related hair conditions, and does not report new findings.
January 1996 in “Springer eBooks” This article describes the balding process as a reduction in hair follicle size rather than a decrease in their number, but it reports no new findings.

April 1994 in “Journal of Investigative Dermatology” Androgen receptors found in monkey scalps, similar to humans, affect hair growth.

August 1993 in “Journal of Cutaneous Pathology” In this study, researchers found that as androgenetic alopecia severity increased, the hair follicle matrix and dermal papilla's volume and cell nuclei number decreased, especially in the papilla.
