Infrared spectra of anagen (A), catagen (C), and telogen (T) hairs obtained on the inferior bulb region (IB), central bulb region (CB), and shaft (S) (1480-950 cm- • region). In the catagen hair, the _epithelial column (EC) is also reported. In the ordinate, absolute absorbance values are reported.
