research Some Histological and Biochemical Evaluation on Commercial Hair Dyes
Commercial hair dyes can harm the skin and liver.
research Effect of Protein Hair Straightener on Hair Shaft by Scanning Electron Microscopy
Protein hair straighteners damage the hair more than hair dyes.

research Repigmentation of Hair After Latanoprost Therapy
Latanoprost therapy potentially caused a woman's white hair to darken again.
research Hair Building Fibers Through the Dermoscope
Trichoscopy can help tell the difference between artificial hair fibers and other scalp artifacts.
research Metabolite Screening of Aromatic Amine Hair Dyes Using In Vitro Hepatic Models
The study investigated the potential oxidative metabolism of nine aromatic amine compounds used in hair dyes using human liver microsomes and hepatocytes. Toluene-2,5-diamine (TDA), p-aminophenol, m-aminophenol, p-methylaminophenol, N,N'-bis(2-hydroxyethyl)-p-phenylenediamine, and 1-hydroxyethyl-4,5-diaminopyrazole showed no oxidative metabolism. While oxidized metabolites of 4-amino-2-hydroxytoluene (AHT), 2-methyl-5-hydroxyethylaminophenol (MHEAP), and phenyl methyl pyrazolone (PMP) were detected, they did not exhibit NADPH-dependent covalent binding, indicating they were not reactive. Further studies in human hepatocytes showed conjugation but no oxidative metabolites for AHT, MHEAP, PMP, and TDA. The findings suggested that the tested hair dye ingredients did not undergo hepatic metabolism to form potentially reactive oxidized metabolites.
research Aging of the Hair Follicle Pigmentation System
Hair grays due to oxidative stress and fewer functioning melanocytes.
