July 2019 in “Experimental Dermatology” This study reported that polyamine levels, especially N-acetyl polyamines, were higher in the vertex region of the scalp than in the occipital region in patients with male and female pattern hair loss.
26 citations
,
May 2019 in “PLOS ONE” This study observed that hair follicles in hair loss patients had increased levels of Propionibacterium acnes, potentially linked to elevated immune response gene expression in miniaturized hair follicles.
2 citations
,
October 2015 in “Indian journal of science and technology” This study found that SM-215 applied to mice increased hair follicle activity and capillary presence, promoting hair growth compared to non-treatment.
January 2014 in “Medical Innovation of China” This study investigated androgen receptor expression in the scalp tissue of androgenic alopecia patients, focusing on hair follicles and sebaceous glands, using immunohistochemistry.
2 citations
,
June 2011 in “Expert Review of Dermatology” This review discusses the characteristics and management options for female pattern hair loss, highlighting the unclear role of androgens and the psychosocial impact, and reports no new clinical results.
30 citations
,
May 2010 in “British Journal of Dermatology” This study found that intermediate hair follicles are morphologically distinct from terminal follicles and offer a novel model for developing new alopecia therapies despite being technically more challenging to study.
January 2008 in “Journal of Clinical Dermatology” This study found that integrin alpha-6 and p63 may play a role in hair loss, with variable expression patterns in different types of alopecia observed in scalp biopsy samples.
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.
4 citations
,
April 2001 in “Experimental Dermatology” This study used a novel HPLC-radiomatic flow scintillation system to measure 5α-reductase activity in dermal papillae from miniaturized hair follicles of the human occipital scalp, revealing significant variability in enzyme activity across samples.
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.
This article reviews various discoveries about hair follicle cycles, androgenic alopecia, and the role of dihydrotestosterone, emphasizing the effectiveness of hair transplantation and reports no new findings.
