Brush Hair Material The Featherstroke brush range includes brushes comprising natural hair, high quality synthetic fibers and a combination of both. Natural Hair Natural hair is very soft and creates a natural look. This type of brush allows makeup to stay in place for longer periods and the application is concise and smooth. Synthetic Fibres Synthetic fibers are less soft and flexible. Whilst these brushes lack the refined touch of natural hair they are more durable and easy to maintain and have the advantage of being less expensive. Combination Combination brushes are a mixture of natural hair and synthetic fibres. This creates a brush softer and more pliable than a purely synthetic brush and has the advantages of natural hair. Each Featherstroke brush has brush hair material individually selected to suit its purpose and application and provides optimal usability and value for money.
