Absolutely. Since peach is an orange-based color, it can get brassy. Add a color-depositing shampoo and conditioner to your routine, but only use purple shampoo and conditioner if your color looks brassy. If you just want a color refresh, add some peach hair dye to your conditioner or use a product like Manic Panic as a leave-in conditioner. If none of this advice works, ask your colorist.
