Confocal microscopy is an excellent method for studying the localizati
on of fluorescent stains. Used in this way, superior 3D images can be
obtained from multiple optical sections with very shallow depth of fie
ld. The main advantage of this technique is that the sample is not dam
aged. We have taken serial confocal sections of hair and via specific
image enhancement routines have obtained high-quality 3D images enabli
ng the visualization of cuticle scale and its pattern of distribution.
This has been done on various types of hair: bleached, permed and in
certain pathological conditions. This first step will allow us to char
acterize the hair surface in terms of its roughness, and the distribut
ion and form of cuticular scale, parameters that have potential in the
assessment of dermocosmetic efficacy.
