This study investigated the effects of different relaxer treatments on African-American hair, finding lab-made relaxer solutions caused less damage to hair topography than commercial systems.

This source highlights the utility of cationic polymers in haircare products for protecting against hair damage from chemical treatments and grooming, and describes how microfluorometry can measure polymer deposition and penetration on hair fibers.

This study found that UV stabilizers must diffuse uniformly and in high uptake levels throughout hair fibers during humidification cycles to effectively prevent photo-oxidative degradation.

This study describes a microfluorometric method to quantify lipid removal and reattachment on human hair during light exposure and chemical treatments, altering hair surface properties from hydrophobic to hydrophilic.

This study found that photochemical and cosmetic chemical oxidation of hair causes surface damage by delipidation and acid formation, which can be characterized and quantified using microfluorometry and X-ray photoelectron spectroscopy.
