How can a level 5 get red brown hair?

A level 5 hair color is typically a medium brown, so achieving a red-brown hue involves adding red tones to the base color. This can be done by using a warm red-brown hair dye or a color depositing conditioner that contains red pigments. It's important to choose shades that complement the existing level 5 color for a natural look. Additionally, a professional stylist can help create the desired red-brown effect through techniques like balayage or highlights.
