research Raman spectroscopy and electronic microscopy structural studies of Caucasian and Afro human hair
Hair treatments cause significant structural changes, especially with excessive heat, regardless of ethnicity.
research Conformational differences in protein disulfide linkages between normal hair and hair from subjects with trichothiodystrophy: A quantitative analysis by Raman microspectroscopy
TTD hair is brittle due to fewer sulfur amino acids and unstable disulfide bonds.
research Enhanced Differentiation Potential of Pigmented Human Epidermal Equivalents
PmtHEE is a better model for studying pigmented skin because it includes melanocytes and shows improved cell differentiation.
research Micro-segmental analysis of the entry pathway and distribution of zolpidem in hair from different scalp regions after a single dose
