Recently I refreshed my ombre' with a blonde-er shade added to the ends. The last time I did anything to it was in July so it was definitely time for a little update! After a while blonde hair starts to loose its white shade and turn orange-y, as seen in the photo below. So unless you are a natural blonde, it is best to refresh the color every 4-6 months. Depending on how healthy your hair is.My ombre' look consists of 4 different shades of color to gives a complete gradiation.
