How long should a typical hair color last?

A typical hair color, particularly permanent hair color, is designed to last between 4 to 6 weeks before noticeable fading or root growth occurs. This duration allows for a balance between vibrant color retention and the natural growth cycle of hair, which usually sees roots growing out as the hair color fades. Additionally, factors such as hair type, the product used, and overall hair health can influence how long the color remains vibrant.

As for temporary or semi-permanent dyes, they may not last as long and are designed for a shorter duration, usually reflecting the options presented. However, permanent hair color is specifically formulated to provide longer-lasting results while reinforcing the integrity of the hair. Hence, 4 to 6 weeks is a realistic expectation for maintaining the appearance of colored hair before touch-ups or reapplication is needed.
