Copper color vegetable dye - Parvati from La Saponaria is a new formula, better color rendering, shorter processing time. It's the color for you if you want beautiful natural highlights, hair that glows with health. It is recommended to prepare your hair: Wash your hair thoroughly with LaSaponaria natural pre-dyed shampoo. Do not use shampoos that contain silicones or other "filming" ingredients in order not to reduce the effect of the tint. Prepare the dye: Put on gloves and in a bowl mix the dyeing powder with hot water (about 70 degrees). Add water until you get a smooth and homogeneous paste, it must not be too liquid or too thick for a perfect application. The amount of powder to use is determined by the length of your hair and must be needed to cover the entire area to be treated. Apply the dye: Apply the paste thus obtained, without letting it cool, on damp hair that has just been washed, separating the hair into strands and starting from the root towards the lengths. Gather your hair and cover it with a film and a towel to keep the heat, leave everything on for 30 minutes to 2 hours. The longer it is left on, the better the color will adhere and will tend to be darker and more covering. Rinse and shine: After the application period, wash your hair with warm water without using shampoo or conditioners. You can optionally do a final rinse with cold water and a hydrosol to better fix the color and close the hair scales. Do not use other products on the hair for at least 24 hours. Store in a cool, dry place.
