Choose a shade close to your natural hair colour: up to 2 shades lighter or darker than your current hair colour.
Since it is difficult to make an already dyed hair lighter, if this is the case with you, choose a darker shade.
If you are a darker or olive skin tone, try the warm brown shades of Kolora. The colder shades are more suited to a cold or pink skin tone.

To ensure proper use, read the instructions leaflet for mixture preparation and application which is enclosed in the hair dye packaging.

Follow these 5 steps for convenient and easy coloration:

• 1. Always perform a skin allergy alert test 48 hours before each use of the product!
• 2. Start the application immediately after the mixture (dye + developer) has been prepared. Do not use any metal tools or containers! 
• 3. Massage the entire length of the hair to ensure better penetration of the dye inside the hair, especially at root level.
• 4. Wait for as long as it is indicated for the hair color to take effect.
• 5. Rinse thoroughly and apply the nourishing care conditioner after coloring. Do not use shampoo to wash the hair dye!
