Synthetic bristles are man-made fibers used in various brushes, including those for painting, makeup, and cleaning. Unlike natural bristles, which come from animal hair, synthetic bristles are typically made from materials like nylon or polyester. These fibers can be engineered to mimic the softness and flexibility of natural bristles while offering durability and resistance to wear. One of the main advantages of synthetic bristles is their ability to hold shape and maintain performance over time. They are often easier to clean and can be more hygienic, making them a popular choice for cosmetic brushes and art supplies. Additionally, synthetic bristles are often more affordable than their natural counterparts.
