What is a stock hair system?

A stock system is pre-made in standard sizes, base types, colors, and densities, ready to ship quickly. It costs less than custom and is a practical way to start or to keep a backup unit. The trade-off is fit: you choose from set options rather than specifying every detail, so the match to your exact hairline, color, and density is close rather than precise. Many men begin with a stock system, then move to custom once they know their preferences. Compare both in Stock vs custom hair systems.
