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.

The Luseta Purple Shampoo and Conditioner Set is designed specifically for individuals with blonde or gray hair looking to maintain their color while minimizing brassy tones. One of its standout features is the intensity of pigment, which effectively neutralizes unwanted yellow hues. The formula is sulfate-free and paraben-free, making it a gentle option for color-treated hair, which many users will appreciate.

In terms of hair type compatibility, this set claims to work for all hair types, including curly and damaged hair, thanks to the inclusion of Cocos Nucifera oil that helps moisturize and repair split ends. This moisturizing property is crucial for maintaining healthy hair, especially for those who regularly color their locks.

The product can be used frequently, but it’s wise to follow the recommended usage to avoid any potential over-toning. The pH balance of both the shampoo and conditioner ensures that the products are safe for use without stripping hair of its natural oils. On the downside, while the shampoo effectively cleans and brightens, some users may find that it requires multiple applications for optimal results, especially if their hair is heavily brassy. Additionally, although formulated for all hair types, those with very oily hair might find it less ideal, as it may not provide enough cleansing power for their needs.
