February 2018 in “Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy” This study successfully used ATR FT-IR spectroscopy to uniquely identify or differentiate human hairs by detecting specific spectral features associated with individual hair characteristics and cosmetic residues on hair surfaces.
18 citations
,
August 2014 in “Lipids” This study found that unsaturated fatty acids are more abundant in the cortex of human hair than on its surface, and steryl glycoside-like lipids may help bind the cuticle to the cortex.
36 citations
,
August 2011 in “Journal of dermatological science” This article examines the role and composition of integral hair lipids in forming a protective barrier similar to the skin's epidermal lipid layer and reports no new findings about their effects.
4 citations
,
July 2010 in “International Journal of Cosmetic Science” This study observed that hair fibers in older women become more curved with age, decreasing hair luster due to their disordered alignment and structural differences between the convex and concave sides.
21 citations
,
July 2010 in “International Journal of Cosmetic Science” This study found that hair luster decreases with age in Japanese females, primarily due to an irregular increase in fiber curvature which affects hair alignment.
January 2009 in “Nihon Keshouhin Gijutsushakaishi/Journal of S C C./Nihon Keshouhin Gijutsushakai kaishi” This study found that the structural and chemical composition of human curly hair may resemble that of sheep wool, implying a shared characteristic among mammals with wavy hair.
254 citations
,
January 2007 in “Chemical Society Reviews” This review discusses the hierarchical structure and chemical properties of hair fibers and offers insights for chemists and biochemists, but reports no new experimental findings.
41 citations
,
May 2005 in “International Journal of Cosmetic Science” This study observed that in Japanese females, hair lipid composition showed significant correlations, suggesting CH and CERs may act as a barrier against sebum-derived lipids.
234 citations
,
February 2001 in “British Journal of Dermatology” FPHL affects hair density and diameter, causing visible hair loss in older women.
27 citations
,
January 1995 This study found that higher melanin concentration in black hair offers photoprotection against sunlight-induced protein damage in the cortex, whereas the cuticle experiences similar photodamage regardless of hair pigmentation.
