1. Use products that are specifically designed for dyed hair. Only specialized products can protect the vibrancy, shine and durability of the dye, such as  Kerastase Reflection, Redken Color Extend Magnetics, Wella Professionals Brilliance and Schwarzkopf Professional BC Color Freeze.

2. After the dyeing process, leave it blank for 2-3 days until you wash your hair, so that the color is fully integrated into the hair. Alternatively, you can use a dyed hair conditioner instead of shampoo.

3. As dyed hair may be brittle and weakened, you should always use a special, soft lashing rubber band, which provides maximum protection against breakage and wear. Also, you should not comb them when they are completely wet, while it is ideal to use a brush with natural hair, such as Moroccanoil brushes or Macadamia brushes.

4. Never expose your hair to the sun without proper sun protection. UV rays in addition to the damage and dryness they can cause to the hair, can change the color of the dye and reduce the vitality and shine. To ensure a long lasting color in the paint, you can use the products of the Kerastase Soleil series, L'Oreal Professionnel Solar Sublime or Wella SP Sun.
