Effect of daily gelatin ingestion on human scalp hair


Effect of daily gelatin ingestion on human scalp hair



Nutrition Reports International 13(6): 579-592



ISSN/ISBN: 0029-6635

The effect of daily gelatine ingestion on human scalp hair was studied in a normal adult population. The most dramatic effect of supplementing the normal diet with 14 g of gelatine daily was an increase in hair diameter averaging 9.3% in the 1st study and 11.3% in the 2nd study. Approximately 70% of the subjects in both studies showed increases in hair diameter ranging from 5-45%. This increase constitutes an improvement in the mechanical properties of the hair. The increase in hair diameter was generally inversely proportional to the initial, pre-dosing value. Within 6 mo. after cessation of gelatine dosing, hair diameter reverted back to its original level. The increase was therefore directly attributable to gelatine ingestion. Yield point and yield extension increased with increases in hair diameter. Yield stress values indicated that strength changes in the hair fibers were due mainly to increases in diameter and not to changes in hair structure.
