Having your colorist (ME) weave in warmer lowlights will fight that washed-out look. When choosing the base color, think buttery or honey tones—not too platinum or beige.
Richer, warmer tones will look fresher. “Cooler, ashy tones can be aging.” Also, if your hair and skin are fairly dark, ease into blondeness with a light-brown base, possibly sprinkled with highlights.That takes the edge off gray and allows you to test going golden. Then, if you like the results, you can go lighter later.
