"Hi. I'm Amelia. I'm going to show you how to dye your hair on top and black underneath. I don't recommend doing this unless you are fairly light to begin with because if you're doing this at home you're not going to get light enough on top. If you're my color. If you're fairly light then what you would do is go to the store and buy a highlight or a high-lift blonde color in the box. And then you would also buy a black or dark brown in the box. You could use a semi-permanent down here and get the same effect but up here you would have to use a permanent color, and I recommend something with an ash base and something that's extremely light, high-lift. It would say high-lift on the box. You're going to want to figure out where you want you're black to begin. Most of the time it should begin below the occipital. On this mannequins head it's a little bit higher. You want to separate that hair. Another technique is you could take this part of your comb and draw a zigzag and that will sort of blend the blonde and the black together a little bit more. Or because if you don't and you're hair's thin then what you might get is when you comb the hair down you'll see a line of black underneath the blonde. So make sure if you're not going to do the zigzag that that blonde is thick enough so you don't see that line and you just sort of see the black peeking out underneath. So you section that off, all the way around. Apply the blonde up here. And I would apply that first. Then you're going to want to take something like a piece of foil. Put that there and then apply your black under here. You do that all the way around and the foil's going to keep them separated. You let that process fully to manufacturer’s instructions. Shampoo it out. When you shampoo it, shampoo it with cold water so that one doesn't bleed into the other. And that's how you get blonde with black underneath."
