IN THIS POST:

Confession: The first couple of years I grew out my hair gray, I was convinced my experience transcended purple shampoo. Actually, it was more like I was running an offense for the “just use regular shampoo” team. I was fine rotating through my roster of favorite clean beauty shampoos. They were cleaning my hair per usual and everything was fine. Until it wasn’t.

RELATED: Gray hair, do care—why to ditch the dye.

About three years into my growth, my hair started taking on a brassy tinge. I couldn’t tell if my whites were actually white or if they were browns that hadn’t turned white yet. It was all getting a bit muddy and I found myself craving something to add brightness, definition, brilliance and clarity to my grays.

And then it dawned on me. I probably need a purple shampoo! Here’s why.



Why does gray or silver hair get yellow or brassy?

Jenn Jones, master colorist and owner of Creature Studio in Atlanta, explains, “Light colored hair like shades of blonde and gray are more susceptible to becoming discolored due to a number of factors like heat styling, medications, product buildup, sun, salt, chlorine and environmental pollutants.”

And she’s right. In fact, UV and heat are the biggest discoloring factors. Research has demonstrated UV turns proteins in hair yellow. Melanin in hair normally prevents hair from yellowing, but gray and silver hair have little to no melanin content to prevent this.

Help reduce brassiness with a clean UV + heat protectant

Using a heat + UV protectant, along with a great purple shampoo, can be incredibly effective at bringing out those white, bright silver and grays—it basically helps stop the yellowing/brassiness before it starts.

I’ve tried a number of ethical beauty heat protectants (read about my full experience, and get full reviews of all the ones I’ve tried here), and hands down, the best one is EVOLVh’s Superfinish Polishing Balm. 

The Polishing Balm stands out to me because it’s water-based and really light and it doesn’t change the texture of my hair. It’s like adding nothing but it’s like adding everything. Check it out: the Polishing Balm defrizzes, adds moisture, softness, shine, strength, prevents breakage, splitting AND provides UV and heat protection. I know. I KNOW!

I add a dollop of this to my hair before every blow dry and it leaves my hair super shiny and soft. #obsessed

Other preventative steps to stop yellowing or brassy hair

We can’t control the melanin in our hair, but we can control any external factors that cause yellowing or brassiness—like the products we choose to use.

Product buildup is a big factor when it comes to yellowing. To avoid it, choose EDTA-free shampoos, which can specifically cause yellowing.

Another preventative measure is to look for shampoos that are rich with plant antioxidants, which help reduce yellowing caused by UV. Antioxidants that are most effective for stopping hair yellowing (UV, heat, iron in water) are the ones that quench the hydroxyl radicals that are causing the yellowing. These are plant sugars like mannitol, quercetin and purple pigments in grapes and cranberry, to name a few.

And since I mentioned it, reducing your exposure to UV rays is key to preventing yellowing of strands. Molecular Biologist and Cosmetic Chemist Kate Noonan explains that hair is made up of 95% keratin protein. When hair is exposed to UV, it breaks down that keratin—specifically the part that gives hair its strength and shine. UV also fades hair color and can create hair-yellowing. Using a hair sunscreen can help with this—and these are my top picks (you know I got you, girl). 

Reducing your use of heat tools like flat irons, curling irons and blow dryers can also significantly reduce yellowing of your hair. Too much heat on gray hair can turn it brassy (or yellowish). That leaves you with a few options:

  1. Stop using heat tools, and when you do, make sure it’s continually in motion (aka, don’t hold your blow dryer stagnantly on one section of your hair).
  2. Choose heat tools that dry or style your hair in half the time, like the Dyson Supersonic Hair Dryer. It also has controlled heat settings that help reduce damage. Not sure if it’s for you? Check out my GRWM video here to see how FAST it dries hair.
  3. Skip heat all together and opt for a heatless styling tool! We’ve been testing a BUNCH of heatless curling options, so stay tuned for our review of the first, dropping later this week!

Why use purple shampoo?

Okay, now on to the purple shampoo! Purple shampoo is actually another preventative measure, but it merits a bit of an explanation, so we are dedicating this entire post to taking a deeper look.

Purple shampoos are called “purple shampoos” because they are actually…PURPLE. Jenn adds, “It’s basic color theory. Purple and yellow are complementary colors. That means when put together, they neutralize each other. These shampoos are going to get rid of unwanted yellow or ‘brassy’ tones in light shades of hair so the hair is left brighter.”

This is DIFFERENT than the chelating or clarifying shampoo, or apple cider vinegar rinses you might have heard of. A chelating or clarifying shampoo can be used to remove any product or mineral buildup that may be contributing to brassiness. ACV is typically used after you shampoo, condition or color because it seals the cuticle down and adds some shine.

What are the active ingredients in purple shampoo?

So the bottom line is that you need something purple in the purple shampoo to get the job done. I’ve seen brands use a myriad of ingredients to attempt this, from botanicals like purple potato, to mineral-derived pigments like ultramarines and iron oxides, to plant extracts like bilberry extract and beet extract, to synthetic dyes (like Basic dyes and Acid Violets). And in a nutshell, I’ve found that the purple shampoos that use vegetable and botanical extracts are a lot less effective compared to purple shampoos that use synthetic dyes.

So then the obvious next question is, what’s the deal with synthetic dyes and do we need to be concerned with using them? Let’s break them down by category to dive in deeper.

Basic Dyes

Basic Dyes (which is actually the proper name for these dyes even though it sounds like a descriptor—”Basic dyes” can encompass everything from Basic Brown 16 to Basic Blue 99 and Basic Red 76, the two we’re specifically talking about here) fall under the category of “coal tar” dyes, which means they are exempt from FDA approval. Coal tar dyes are synthetic dyes and contain petrochemical derivatives. 

From what we can see, each of the Basics comes with its own set of things to consider, some of which we highlight in our look at Overtone

For example, we checked in with clean cosmetic chemist, Ayurvedic practitioner and founder of KKT Consultants, Krupa Koestline, who explains, “Basic Blue 99 [what we see in some purple shampoos] has been determined okay to use by the Cosmetic Ingredient Review Expert Panel (CIR) and the EU Safety panel, but have noted that the structure and composition can vary quite a bit and so that can be an issue if not properly tested.” 

She continues, “Basic Red 76 [also what we see in some purple shampoos] is an ‘azo-dye’. Basic Red 76’s safety in use is inconclusive per [the] EU. The Scientific Committee on Consumer Safety (SCCS) in an Opinion, SCCS/1385/10, has classified Basic Red 76, when used as a non-oxidative hair dye up to 2%, as not posing a risk for consumers. However, Australia doesn’t allow the dye and differs in opinion. The concern is the presence of o-ANISIDINE, which is a carcinogen.” The muddy waters around this specific issue are also illustrated in this challenge paper

Like with anything, it’s about the quality of the ingredients, the percentage of the ingredient and how much you trust the company making the product. Which leads us back to marketing lingo, greenwashing and transparency

Takeaway: Do I want to drink this? No. Am I okay with using a tiny percentage in my purple shampoo? Yes, I am.

Acid Violets

Violet 2 (also known as Ex D&C Violet 2) and Acid Violet 43 used to be derived from coal tar, but are currently made during petroleum jelly refining. They routinely bear a “caution” statement regarding potential skin irritation and instructions for determining whether the product causes skin irritation in any given individual, so I wanted to do a little digging to see why.

Krupa explains, “Acid Violets are safe to use and don’t have any safety issues associated with them, in hair shampoo/conditioner application. They are both not recommended to be used on mucous membranes, but otherwise no other concerns.”

In some additional research and with help from Kate, we were able to add a little more color

  • Both Violet 2 and Acid Violet 43 are not mutagenic in any of the tests like the Ames test or the micronucleus assay. 
  • Violet 2 in a 1% concentration shows no system toxicity and no significant local skin reactions. 
  • Acid Violet 43 was determined to be safe for use in hair dye formulations, when impurities are limited. The Scientific Committee on Consumer Safety is of the opinion that the use of Acid Violet 43 as a non-oxidative hair dye with a maximum on head concentration of 0.5% active dye does not pose a risk to the health of the consumer.
  • The CIR (the US Cosmetic Ingredient Review panel) found that no dermatitis was seen when many human volunteers at different Derm centers had 1% Acid Violet 43 in petrolatum applied to their skin over a 6-month period.

To put all this in context, Kate explains, “Often, just a 0.3% concentration of Acid Violet is needed to treat hair brassiness.”

Takeaway: With all that in mind, the concentration of dyes like Acid Violet 43 and Violet No. 2 that we find in the purple shampoos I’m trying and recommending are considered safe, both by the FDA and by my trusted cosmetic chemist sources.

Plant-derived “botanical” dyes in purple shampoo

The FDA classifies color additives obtained primarily from mineral, plant or animal sources as “not subject to batch certification requirements.” This means that the FDA doesn’t need to review each batch of these colorants, and that cosmetics companies can include them without having them reviewed by the FDA’s certification. But, says the FDA, they “still are considered artificial colors, and when used in cosmetics or other FDA-regulated products, they must comply with the identity, specifications, uses, restrictions, and labeling requirements stated in the regulations.”

Takeaway: Again…this comes down to the transparency of the brand and how much you trust their practices. A trustworthy brand will do its research and comply with regulations, as well as provide clarity on the ingredients in its products.

Should I use blue shampoo for my gray hair?

NO. Purple shampoo is not to be confused with blue shampoo, which is used for darker hair to cancel out orange tones. Jenn warns, “Never put blue, even pale blue, on blonde hair when trying to cancel out yellow tones. Blue + yellow = GREEN.”


How to find an all-natural purple shampoo that’s right for you

A collection of purple shampoos lined up on a bathroom sink.
Some of the purple shampoos tested for this post.

MOST of the purple shampoos on the market are formulated with other health-compromising ingredients like surfactants, parabens, fragrance and more, like DMDM Hydantoin. DMDM Hydantoin is a formaldehyde-containing ingredient and it’s sometimes listed (sometimes not if it’s hidden in a surfactant).

BUT! I was able to hunt down a few cleaner options that are formulated without all the junk. Purple shampoo is currently an incredibly niche piece of the clean beauty market (though it’s rapidly expanding, as evidenced from the new formulas I’ve recently tried), and each brand I’ve found formulates a bit differently.

Finding a “right fit” purple shampoo is really about taking into consideration your own type of hair and balancing that with how aggressive of a treatment you want. What it really comes down to in the end, as always, is making an educated decision about what you personally want.

How do I use all-natural purple shampoo?

If you’ve tried using purple shampoo to brighten your gray (or blonde) hair, but it doesn’t work—you *might* be doing it wrong. The trick? You have to leave it in and let it actually tone your hair!

Of course potency and efficacy can vary from brand to brand depending on percentages and ingredients, but if the question is “Does purple shampoo work?” the answer is YES, AND (!!) if it’s not working for you, you most likely are not giving the pigment enough time to transfer. 

The best way to use clean beauty purple shampoos is:

  • Apply on wet hair in the shower.
  • Wash hair as normal, but don’t rinse.
  • Let the shampoo sit on your hair for a few minutes (sometimes directions even say this explicitly) before rinsing. You can even take a clip into the shower and clip up your hair as you take this time to do all the other things like wash your face or shave. This gives the color a chance to work so you are not applying it and rinsing it off straight away.
  • Once you’ve let it sit, rinse out and conditioner like normal.

Here’s a quick video of me trying out my favorite brand or purple shampoo…

You will also have to play with frequency, depending on how often you wash your hair and the needs of your own gray hair. For the person who washes daily, you may only need to use a purple shampoo a couple times a week to get those grays non-brassy and bright. Or for the person who only washes their hair once a week, you may be able to use a purple shampoo every time you wash.

It also depends on the shade of your hair. Jenn explains, “Anyone can use a purple shampoo; you just won’t get benefits from the color unless your hair is a level 8 [a medium blonde on the hair tone scale] and above. The pigment is just not strong enough to do anything to darker tones.”

The goal here is to determine your own personal equation of frequency, taking into consideration shampoo formula, hair type, hair shade, hair texture and personal washing frequency.

What if my hair turns purple?

If your hair happens to turn purple, Jenn suggests that “a clarifying shampoo will typically work well to pull out unwanted tones. You can apply the shampoo and let it sit for a while to help pull out the color. Typically, if your hair is over-processed or porous, the color can build up, usually on the ends, and be harder to get out.”

I have been interest in Dr Craft for a while and really like the idea of them using blackcurrants to obtain the purple colour . Let’s hope they will be able to ship internationally soon . Thanks again for a great review !

    Thank you for this very informative list. It’s so time consuming to search for truly natural hair products, especially purple shampoo.

Since going gray, I’ve FINALLY gotten to the stage where I only shampoo about 1-2 times per week. I started using a store brand purple shampoo about 2 months ago but think I’ll switch to something you recommend.

    What type conditioner do you recommend?

    I have been using BoldUniq shampoo and mask for several months now. I did not get the conditioner but wish I had. It’s doing the job of toning down the remaining blond. However it seems too purple. I’ve been experimenting with timing and how often to use it. I wash my hair twice a week. Rarely use conditioner because it makes the hair too limp. This product appears to be a much better one than the old Clairol Shimmer lights.
