Five Sulfate-Free Purple Shampoos that Keep Your Blonde Bright

As beautiful as they are, light hair colors, can quickly lose their luster. Blonde colored and highlighted hair may turn yellow/brassy surprisingly quickly after having it dyed. Gray hair loses its brightness and shine as you age and becomes prone to picking up unattractive yellow tones. Platinum blonde hair looks gorgeous, but it requires a lot of care to keep it bright.

Light-colored hair is likely to suffer discoloration when exposed to the sun, hard water, and other environmental pollution. Frequent dyeing also results in porous hair that is prone to discoloration.

Fortunately, there are highly efficient and affordable products developed to control discoloration and to remove unwanted brassy and yellow tones from blonde and gray hair.

Products that keep the color fresh and beautiful

The simplest way to prevent discoloration and neutralize undesirable yellow and brassy tones in blonde hair is to use a purple shampoo. Purple shampoos contain violet pigments that counteract brassiness in natural or enhanced blonde, white, and gray hair.

Unfortunately, many purple shampoos can dry out your hair, especially when used on a regular basis. Considering that your bleached hair is already dry and porous—not a great combination.

To avoid dryness, you can alternate a violet shampoo with your regular shampoo, but this won’t make much difference if your regular shampoo contains harsh sulfate cleansers. Using sulfate-free purple shampoos is a better way to prevent your hair from drying out. These shampoos are gentle to your hair and some can be used regularly.

Below is a list of sulfate-free purple shampoos that use natural ingredients to combat brassy and yellow tones and to keep your hair hydrated, soft, and manageable.

Suggested Use

Wash the hair with your regular shampoo to remove any build-up and make depositing purple pigments easier. Wear gloves (included in the packaging) and apply the product to wet hair. On first use leave it on for up to 3 minutes.

The results will vary depending on how long you leave it to sit in your hair. 1-5 minutes will be enough to remove brassy/yellow tones. To achieve silver or ash-grey tones, let the product sit for 10 to 20 minutes. If left for too long, it may turn your hair purple or grayish. Use a clarifying shampoo to wash out purple tinge from the hair.

Use this shampoo several times a week, along with your regular shampoo and conditioner. The frequency of use depends on the level of discoloration and results you’re looking for.

Make sure to follow with a good moisturizing conditioner to reduce the drying effect.

2. PRAVANA THE PERFECT BLONDE Purple Toning Sulfate-Free Shampoo

This deep, dark purple shampoo uses an exclusive dual ultra-violet dye system & optical brighteners to neutralize brassiness and to brighten blonde, silver, or highlighted hair. It also contains hydrolyzed keratin and wheat and silk amino acids to boost hair strength, shine, and elasticity. The formula is free of sulfates, parabens, phthalates, salt, and gluten. It is also cruelty-free and 100% vegan.

This violet shampoo doesn’t lather as much as ordinary shampoos do and, consequently, it doesn’t spread well thorough your hair. You would need to add more product to completely saturate your strands, especially if your hair is oily. Mixing this purple toning shampoo with your regular shampoo helps to create more foamy lather and makes the shampoo mixture more spreadable.

In addition to enhancing blonde and gray hair, it helps red hair to stay vibrant and adds shine to darker shades.

The formula includes UV protectors to prevent your color from fading and to extend the time between salon visits. Keratin amino acids help reduce breakage and make your hair feel healthier.

To prevent dryness and tangling, use a good moisturizing conditioner.

L’Oreal Paris Ever Pure Blonde sulfate-free shampoo promises visible results in just one use. It is designed to stop the yellowing and enhance the brightness and shine of light-colored hair.

Unlike sulfate-based purple shampoos, which can leave your hair dry and prone to tangling, this brass-fighting shampoo hydrates over-processed hair, leaving it soft, tangle-free, and easy to manage.

If you want to stick to your regular shampoo, while enjoying the benefits of purple toning pigments, you can control the appearance of brassiness by adding few drops of Mixed Feelings Leave-In Blonde Drops to your regular shampoo or conditioner.
