Extensions blend with the lower part of your hair. Roots are often darker, while ends can be lighter or warmer, so the ends matter most.
If you are between shades, highlighted, balayage, or dimensional colors usually blend more softly than a flat solid color.
Black hair can be soft black or dark brown. Brunettes can be warm or cool. Grey, blonde, and balayage shades should be chosen by the overall look, not one bright strand.
Shade, install method, and care routine all help you choose the length, weight, and color more confidently.
