So what are lowlights? Just as highlights lighten hair with strands of lighter color, lowlights add dimension with strands of darker color. With lowlights and highlights, your hair color may look more natural. My stylist paints in color that's a shade or 2 darker than my natural hair color, which is dirty blonde. She then follows that by painting my next strands lighter. When she's done, my hair is full of beautiful, naturally looking colors.
Lowlights work well on all hair colors. Your stylist may choose to paint in a red, auburn or brown color, perhaps even black. For the most natural color, she or he will likely stick to a shade that's no more than 2-3 shades darker than your natural color.
