LAnza Color Preserving Mask, suitable for color-treated hair. Preserves and prolongs the vitality of hair color while preventing fading. Application method: Before the mask, it is necessary to wash your hair thoroughly. When the hair is clean, the product can penetrate to the last layer of the hair. It is preferable to wash with lukewarm-hot water, as this opens the pores of the hair. Squeeze the hair to remove excess water. Take an amount of about two walnuts and apply to damp hair, preferably from the middle of the hair to the ends, massaging gently so that the product is well absorbed. Leave the mask on for as long as possible to work its way through the entire length of your hair. An ideal time is 5 minutes. Rinse thoroughly. It is recommended to rinse with lukewarm to cold water, so that the hair cuticles close and all the nutrients are locked in. There are also creams that you can leave in your hair without rinsing (leave on).
