Hair Biology and Care Product Ingredients from Marine Organisms

The document from December 20, 2011, explores the potential of marine organisms as a source of ingredients for hair care products aimed at treating alopecia and promoting hair health. It outlines the biology of hair, the hair growth cycle, and the influence of genes and hormones on these processes, noting an increase in hair loss due to lifestyle and environmental changes. The paper discusses various types of alopecia and their causes, including genetic, immunological, hormonal, and stress-related factors. It highlights a shift towards natural ingredients in hair care, with marine algae and fish extracts being identified as rich in minerals, vitamins, amino acids, proteins, and essential fatty acids beneficial for hair growth and health. Species like Palmaria palmata, Ecklonia cava, and Undaria pinnatifida, as well as cartilaginous fish extracts, have shown promise in promoting hair growth. However, the document concludes that while marine-derived ingredients are promising due to their nutrient content and low production costs, more human clinical trials are needed to confirm their effectiveness.
