Root Shadow vs. Root Smudge

Root shadow and root smudge terminology can vary by salon. This future guide will compare the visible root depth, transition width, opacity, grow-out, and tonal upkeep rather than treating either name as a fixed formula.

Root shadow and root smudge can describe overlapping salon services, and usage is not universal. This URL is reserved for a future comparison; for now, describe the root depth, transition width, opacity, and grow-out you want, then ask the colorist how their chosen product and technique will create that result.
