A: There is no specific color that makes the hair look “longer”. And while the color won’t make a dramatic difference in the length your hair appears to be, certain hair coloring techniques are more likely to enhance the
appearance of length than others.
For instance, heavily highlighted and lowlighted hair that uses distinctive color variations tend to break up the focus of the eye when it is being viewed. The eye jumps from streak
of color to streak of color, and this generates a horizontal focus.
However, coloring the hair in a single, flattering color generates a uniform palette off which the light can be reflected. Doing so allows the length of the hair to create the focus
which will be vertical and will draw attention to the length of the hair rather than the variations in color.
This is especially true when dealing with “at home” color kits. The highlighting and lowlighting methods of the at-home kits create streaks of color that are a lot LESS subtle than
their professional counterparts.
