Kari’s tip: Whether you’re going red at home or at the salon, you should wait to shampoo for at least 24 to 48 hours after the color processing. It will help your hair hold the color longer.
What it is: Highlighted hair with darker roots. It’s one of our favorites because it buys a little time between touch-ups.
Who it’s best for: Anyone with highlights.
How to do it: Do a full head of highlights in a shade close to your natural color, and then come back in with a darker shade to deepen and soften the roots.
Kari’s tip: If you’re trying it at home, there are two ways to get the look. The first is for unbleached strands: Add highlights, but avoid your roots. The second is for already-highlighted hair: Choose a color a hint darker than your highlights and massage it in only at the roots.
