Blonde hair dark under, or the "shadow root," is a hair coloring technique that creates a subtle, natural-looking gradient from dark roots to blonde ends. Unlike traditional highlights, which involve bleaching the entire head of hair, the shadow root technique only targets the roots, leaving the mid-lengths and ends of the hair their natural color or a slightly darker shade.
This technique has gained popularity in recent years due to its low-maintenance nature and ability to enhance the hair's natural dimension and texture. The dark roots create a flattering contrast against the lighter ends, which can help to frame the face and accentuate facial features. Additionally, the shadow root technique is less damaging to the hair than traditional bleaching methods, as it only involves coloring the roots.
