A shadow root is a coloring technique where the roots are kept or colored slightly darker than the rest of the hair and blended softly into the lighter lengths. Here's what sets it apart, who it suits, what to ask your colorist for and how to keep it looking fresh.

Shadow root at a glance

  • Type: Technique
  • Tone: A shade close to your natural root color
  • Lightening needed: No. It's done with a deposit-only color at the root.
  • Maintenance: Low

What to ask your colorist

  • Say how far down the darker root should extend.
  • Ask for a shade close to your natural color.
  • Ask for a soft blend with no line.
  • Bring photos taken in daylight, and say what you don't want as well as what you do.

How to maintain it

Use color-safe shampoo. The root color is demi-permanent and fades gradually.

Shades and variations

  • Root smudge: a small blur right at the root, about half an inch, to soften foil lines.
  • Shadow root: a deeper root, one to two inches, for a lived-in look.
  • Root melt: the longest blend, where the root color melts into the mid-lengths.
  • Root tap: the lightest version, just touching the root.
