HAIR COPPER AND ZINC CONCENTRATION IN PREMATURE HAIR GREYING
Elham Mohamed Hassanin;
Abstract
Premature canities is a genetically determined phenomenon that is usualy age related and can be accelerated by some exogenous factors.
Previous studies measured Cu and Zn only in serum of patients with premature canities and found significantly lower serum Cu levels in patients compared to controls and no significant difference regarding serum Zn.
The aim of this study was to assess the hair Cu and Zn levels in premature canities.
This study included 40 patients under the age of 25 years with premature canities "diagnosed by having at least 10 gray hair fibers in the scalp" and 40 age and sex matched healthy controls. Patients were further subdivided into 2 groups according to the presence or absence of family history "in first degree relatives" of premature canities.
Non grey clean hair that has not been treated for three months was sampled from the nape of the neck close to the scalp, as strands 3-5 cm long weighing 1-2 gm.
Hair was digested by microwave digestion method and the concentrations of Zn and Cu were measured using atomic absorption spectroscopy.
