This hair care product is specifically formulated for blonde, bleached, highlighted, or grey hair. Its primary function is to neutralize unwanted yellow or brassy tones, enhancing the vibrancy and coolness of lighter hair shades. The product typically contains violet pigments, which counteract yellow undertones, resulting in a brighter, more balanced color. For instance, after several washes, blonde hair can develop a yellowish tinge; this product helps to correct that discoloration.
The importance of such a product lies in maintaining the desired hair color between salon visits. It extends the life of color treatments and prevents the progression of brassiness, which can make hair appear dull and aged. Historically, remedies to counteract brassiness involved natural ingredients like blueberries or vinegar rinses. Modern formulations offer a more convenient and effective solution, often incorporating moisturizing and nourishing agents to prevent dryness and damage associated with color-treated hair.
