A common characteristic of synthetic hair is that it is?

Synthetic hair is typically made from various types of man-made fibers, which can be produced at a lower cost compared to natural human hair. This manufacturing process allows for synthetic hair to be sold at a more affordable price, making it an attractive option for those looking for budget-friendly hair extensions or wigs.

While options about being easy to style, color-resistant, or having a soft and sleek texture may apply to certain types of synthetic hair, the primary characteristic that sets synthetic hair apart in the context of affordability is its lower price point. Human hair is generally more expensive due to its natural properties and demand, while synthetic options can provide a variety of looks without the higher cost associated with human hair products.
