March 2005 in “International Journal of Cosmetic Science” This study found that menopause alters hair lipids and reduces hair quality, with hormone replacement therapy mitigating some changes.
29 citations
,
April 2003 in “Experimental dermatology” In this study, in vitro growth of human hair follicles did not alter hair keratin expression patterns, maintaining follicle integrity and proper keratinization similar to in vivo conditions.
425 citations
,
August 2002 in “BioEssays” This review discusses the structure and assembly of the cornified cell envelope in stratified squamous epithelial cells and various disorders leading to barrier defects, but reports no new findings.
45 citations
,
February 2002 in “International Journal of Cosmetic Science” This study found that a ceramide derived from sphinganine can bind to African–American hair, reducing breakage when applied in a shampoo after relaxing treatments.
11 citations
,
February 2002 in “International Journal of Cosmetic Science” This review describes recent findings in hair biology, highlighting the diverse molecular signals that regulate hair growth and pigmentation, but presents no new experimental results.
13 citations
,
January 2001 in “Skin pharmacology and physiology” This article discusses a new device for visualizing and quantifying skin distribution of a radioactively labelled compound, but reports no new clinical results.
30 citations

September 2000 in “Journal of Dermatological Science” This study reports that the fatty acid composition in cell membranes of stratified squamous epithelium varies with keratinization patterns, showing a partial essential fatty acid-deficient state in cultured keratinocytes.
28 citations
,
July 2000 in “PubMed” This study found no structural differences between in vitro and in vivo grown hair, with keratinization and organization of keratin being comparable in both settings.
133 citations
,
July 1994 in “Journal of Dermatological Science” In this study, the researchers developed an in vitro model that maintains human hair follicles to grow at in vivo rates and observed that factors like EGF and IGF-I influence hair follicle growth and catagen entry.
