Like with any other hair color, you have to think about your skin to achieve the right tone up top. When going for that auburn-copper color with fair skin, ask for shades that are heavy on the copper and orange sides of the color. Darker skin can handle the more auburn and honey undertones.
Do you want dimension?
If the answer is yes, don't be scared to add some blonde. I know, I know -- I just said you don't go blonde in the fall. But if your whole head is a deep auburn and you want to add a little flair, you can ask for some golden blonde streaks through your tresses, emphasis on the gold.
You can also request color melting, which takes on the effect of balayage without getting the whole process done. Your stylist can add a color a few shades lighter than your base color just to the ends of your hair for some flow.
Think about the future.
That being said, if you're planning on keeping the pumpkin spice look into the winter (or if you're getting a late-in-the-season jump on this trend), ask for darker, brunette highlights or even balayage to stay in season.
Budget. Sorry 'bout it.
The base of this hair color is, in essence, red. As a rule, red dye washes out and fades quicker than any other hair dye. So, if you're adding a pumpkin spice look to your whole head, roots and all, just be prepared to make a few different salon visits before the season is up.
Head to a pumpkin patch, go apple picking or don your favorite flannel blanket scarf and bask in the overwhelming fall-ness of your new look.
