Yes, purple shampoo can subtly fade certain dyed colors and dull vibrant tones, but its main job is to neutralize unwanted yellow/orange brassiness, not strip color; it won't remove deep fashion colors but can make warm reds appear duller or cooler and potentially leave a muddy tint if used excessively on already cool tones. It's designed to tone and maintain color, especially blonde, not drastically fade it, but overuse can mute vibrancy and create a grayish or dull effect by depositing too much pigment.
Hairstylist here, purple shampoo WILL NOT stain your hair any tint shade or vibe of purple but it also wont remove color it can TONE out brassy oranges and yellows and that's about all it does.
Wait 24--48 hours if you experienced scalp irritation, chemical burns, or excessive dryness during bleaching. If no irritation occurred, many stylists recommend using purple shampoo as early as the first wash (48--72 hours is common advice) to begin toning unwanted brassiness.
Your hairdresser likely advised against purple shampoo to prevent dryness, dulling, uneven color (ashy/muddy), or over-toning (purple/blue tint), as it's a temporary fix not for everyday cleaning, and can interfere with future coloring by creating buildup, especially if your hair is very porous or already a bright, cool blonde. They might prefer professional toners, moisturizing treatments, or detox shampoos for better, healthier results.
Purple shampoo can be drying, especially for grey hair , which tends to be more porous. Using it too often can lead to dullness or purple cast on grey hair and increased dryness or brittleness, especially if your hair is already fragile. So just use the Olaplex once a week.

What are the worst shampoos for hair loss?
Purple and blue shampoos help neutralize brassy tones in your hair, helping to lighten dyed hair and create a more desired shade.
Purple shampoo is an essential tool for anyone with dyed blonde hair looking to keep their locks vibrant and fresh. It contains a violet pigment that works as a toner to counteract brassy tones and yellowing, which can occur over time.
Avoid Heat Styling
Heat styling with a curling iron, flat iron, or crimper can cause color to fade severely on color treated hair. You should always use a heat protectant before using hot tools on color treated hair. Heat dehydrates hair and causes damage to the strands, meaning pigment escapes from the hair strands.
A bleach bath typically lifts hair 1 to 3 levels, offering a gentler lift than traditional bleaching by diluting bleach with shampoo and applying it to wet hair, making it great for removing toner, correcting color, or subtle lightening, though results vary based on your starting hair color, porosity, and developer strength.
The hardest hair colors to remove are typically black and vivid reds, due to their dense pigment load and strong staining power, often requiring multiple bleaching sessions; while vivid blues and purples are also very difficult, especially cool-toned ones, because their small dye molecules deeply bond to porous hair, making them stubborn to lift.
While your stylist provides that crucial initial toning, you can typically begin incorporating Redken purple shampoo approximately one to two weeks after your professional salon service, or as soon as you first begin to notice any subtle hint of brassiness returning.
Sulphate-rich shampoos are ideal for stripping hair since they help to release the colour - especially with dark or vibrant colours. These include clarifying or deep cleansing shampoo or anti-dandruff shampoo.
The "Big 3" hair loss treatments, popular in forums, are Minoxidil, Finasteride, and Ketoconazole shampoo, often combined to tackle hereditary hair loss (androgenetic alopecia) by boosting growth, blocking hormones, and reducing inflammation. Minoxidil (Rogaine) widens blood vessels, Finasteride (Propecia) blocks DHT, and Ketoconazole fights scalp fungus and inflammation, with microneedling sometimes considered a fourth addition.
Signs and symptoms of hair loss may include:
Hair loss can signal deficiencies in nutrients like iron, Vitamin D, Zinc, Biotin (B7), B12, and even Vitamin C, as these support follicle health, oxygen supply, and keratin production, but it's crucial to see a doctor for blood tests to confirm which nutrient you're lacking, as excess vitamins (like A or Selenium) can also cause hair loss, notes Harvard Health and The Hairy Pill.
The main downside of purple shampoo is that overuse can lead to hair becoming dull, dry, brassy, or even tinted purple/ashy because it deposits pigment and can strip moisture, so it should be used as a treatment (once or twice a week) rather than a daily shampoo, with plenty of conditioning afterward to counteract dryness. It's a toner, not a cleanser, and excessive use can build up, making hair darker or harder for stylists to work with.
The way it works is all down to the science of the colour wheel. As purple is opposite to yellow, this counteracts the brassiness and neutralises it to maintain your colour's radiance for longer. It helps to prevent that dreaded colour fade, whilst emphasising the shine and vibrance of surrounding darker hairs.
You'll be pleased to know that your hair isn't going to be purple forever, purple shampoo will slowly wash away from your hair, when this happens we always advise our clients to just wash their hair a few times with regular shampoo until some of the pigment starts to come out.

Luckily, there are several ways to remove red hair dye such as washing more frequently, using a DIY vitamin C hair mask, or doing a bleach bath. The approach you choose should depend on whether you're dealing with semi-permanent or permanent color, as permanent formulas typically require more intensive removal methods.
This might be the case for some people, but there's also the risk of more porous, damaged sections of the hair (the ends) absorbing more pigment than the newer hair towards the root. So, to avoid a patchy purple effect, use the Blonde Assure Color Toning Purple Shampoo as advised: on wet hair.
