Chọn tông màu lạnh hoặc màu tro. Chuẩn bị sẵn dầu gội khử màu (toning shampoo) để đề phòng tóc chuyển sang màu đồng thau.

Demi-permanent dye contains small amounts of peroxide, so it can lighten your hair to a certain degree. It's a good choice if you want to go a tiny bit lighter. Permanent dye is much stronger and can lighten your hair up to four levels; unfortunately, it is also more damaging. Semi-permanent dye will not lift color. It will only deposit more color. Light colors will not show on dark hair, period. Brighter colors, such as blue or purple, will show up, but they will be very dark. They may show up as highlights in the sun; they may not show up at all under other lights. Look for "punk" hair dyes, such as: Directions, Manic Panic, and Special Effects. There are dyes made specially for brunettes, such as Splat hair dye. These products are still fairly new and come in limited color options, such as purple, red, and blue.. When out shopping, look for labels that say something to the extent of: For Dark Hair. You can also try a color-depositing dye, such as Splat or Manic Panic. These dyes are concentrated, and may show up better on dark hair compared to other types of hair dye. Dark hair tends to go brassy when lightened. If you use a warm-toned hair dye, this will make your hair appear even warmer. In some cases, it can even make your hair look orange. Using a cool or ash-toned hair color will help balance out the red tones and give you a more accurate hair color. You don't have to do this, but it would be a very good idea to do so. Like previously mentioned, dark hair tends to go brassy or orange when lightened. Washing your hair with purple or blue-tinted toning shampoo will help neutralize the brassy, orange tones.
