Schwarzkopf Activating Lotion is one of the products of the Igora Vibrance line. The indicator 1.9% is relative to the volume of the lotion, which is number 6. Because this volume is the lowest, the power to lighten hair is low. Therefore, it should be used for colour baths. The presentation of the lotion is 1 liter.
The effectiveness of this product derives from complementing it with the dyes of the same line. It also has a light scent that allows perfuming the hair after its application. When mixing it, it is important to consider that you need 1 part of the dye and 2 parts of the activating lotion. So when the lotion comes in contact with the dye, it thickens it and turns it into a cream.
