10 Best Purple Shampoos 2025 in the United States

The Amika Bust Your Brass Cool Blonde Strength Repair Shampoo is designed especially for chemically treated hair, such as bleached or color-treated blondes, aiming to tone down unwanted brassy or yellow hues. It offers a gentle cleansing action while strengthening hair to help prevent breakage, which benefits hair that feels fragile after coloring. The purple pigment helps neutralize brassiness, making it suitable for mild to moderate toning.

This shampoo is formulated to be gentle enough for regular use, but since it’s targeted at treated hair, monitoring usage to avoid drying out strands is advisable. Its amber scent is pleasant and not overpowering.

For those with chemically treated blonde or highlighted hair seeking a shampoo that tones brassiness and helps strengthen hair, this could be a good fit. If a very moisturizing formula or stronger pigment intensity is desired, additional products or conditioners might be needed to complement this shampoo.

Matrix Brass Off Blue Shampoo is designed especially for lightened brunettes and dark blondes who want to reduce brassy, orange tones in their hair. It uses blue-violet pigments that gently tone down unwanted warmth, making it a good choice if you have color-treated or natural hair in these shades. The shampoo cleanses without stripping your color, which helps maintain your hair’s vibrancy. It also offers some moisturizing benefits, so your hair won't feel dry after use.

For best results, the shampoo should be used every other day and left on the hair for a few minutes before rinsing, which helps boost its toning effect. The shampoo is part of a system that includes a conditioner and a neutralization mask, which together provide more intense brass control and moisture. The pigment intensity is moderate, so it may not be enough for very strong brassiness or for those expecting a very dramatic tone change.

This shampoo is effective for subtle toning and daily care of light brunette or dark blonde hair. However, if your hair is very light or heavily brassy, you might need a stronger or more specialized product.

Redken Blondage Color Depositing Purple Shampoo is designed specifically for blonde, bleached, or highlighted hair that tends to develop unwanted brassy or yellow tones. It uses strong purple pigments to neutralize these warm hues, helping maintain a cooler, brighter blonde. The shampoo also contains salicylic acid, which supports strengthening and repairing fragile, chemically treated hair from within.

Thanks to ingredients like wheat protein, amino acids, and glycerin, it provides good moisturizing benefits, leaving hair smoother and shinier without feeling dry or stripped. This makes it a great option if your hair needs both toning and nourishment. While the shampoo effectively keeps color vibrant and reduces brassiness, it is best suited for chemically treated hair rather than natural or untreated hair. It can be used regularly, but because of its pigment intensity, many find using it once or twice a week sufficient to maintain desired results without over-toning. The formula is sulfate-free, which is gentler and less drying for color-treated hair. One thing to keep in mind is that the orange scent may not appeal to everyone.

For those with blonde or highlighted hair seeking a reliable product to combat brassiness while caring for their hair’s condition, this shampoo offers a strong balance of color correction and moisture support.
