Red and black split dye divides the hair at the part: one half a saturated red, the other jet black. The black half is easy. The red half is the work, because red needs a lifted base to show and fades faster than any other shade, so the two sides age at different speeds.

The black half is as dark as hair color goes and gives the red something to push against, which makes the red read more saturated than it would on its own. Red is the fastest-fading pigment there is: the molecules are large and wash out from the outside in, so that half loses depth while the black stays exactly where you put it. Expect the red to drift orange at the ends before it goes pale.

Undertonecool, warm. The black is cool and the red carries warmth, so each temperature has a place to land and the pairing holds up against fair and deep skin alike.
Starting pointThe black side goes straight over any starting depth with nothing lifted, while the red side needs pre-lightening to level seven or lighter or it barely registers on dark hair.
UpkeepRefresh the red with a color-depositing mask weekly and a full application every four to five weeks; the black only needs a root touch-up as new growth shows.
