For the most vibrant result apply to pre-lightened hair. Pre-lighten to the desired level of lift with a bleaching powder + activator (hydrogen peroxide) mixture. It is important to note that the degree of lift achieved with pre-lightening will directly affect the vibrancy and intensity of the final result. For most vibrant results apply to hair lifted to a 7-10 (natural blonde - platinum blonde).
Underlying exposed contributing pigment must be taken into consideration for target color result: if the hair is orange or a dark yellow this will contribute to the final color.
After pre-lightening, shampoo with mild shampoo. Dry the hair. Apply the chosen Silk Elements Color FX Semi-Permanent Color shade directly on dry hair, distribute it evenly and process for 20 to 40 minutes depending on the level of color intensity desired. Strand test every 5-10 minutes. Heat is not necessary for processing if the hair has been pre-lightened. After processing, thoroughly rinse with water and apply a post color conditioner or post color mask to close the cuticle and lock the color deep inside the hair.
