Why do we dye grey hair with purple shampoo?Strange Color Wheel

If you’re a certain age — 30 or 40, or, if you’re particularly ahead of the game, in your mid-to-late 20s — you’ve probably noticed some sly white hair coming out of your part, Either frost builds up above your ears, or builds up in streaks at your temples. If you’ve gone a step further than that, say, with a full-on silver fox blast, you’ve probably tried a shampoo or two designed for gray hair. That means you’ve probably noticed something unusual: the products are as purple as pansies, plums, and like forgotten CSA eggplants rotting in your crisper.

Recently, I found myself wondering why. So, I decided to do a little digging, which only added to the grey hair problem. If you are wondering about these things too, please join me.

So, what’s up with all the purple shampoos?

Gray (and bleached blonde, for that matter) hair can sometimes take on a rusty hue—or, in the parlance of the hair world, it can “turn brassy.” (Like, your hair turns the color of brass. Duh.) Why does this happen? The biggest reason is the sun, whose UV rays tend to strip bluer tones in gray hair and lighten orange ones. Other factors include heat setting tools, drugs, salt, chlorine, and airborne contaminants, but whatever the cause, the purple solution is based on the color wheel. What is the opposite shade of brassy yellow? Violet blue. So the idea is that if you pour something of this color on your hair, you’ll offset any ginger.

What ingredient makes them purple?

Hair care brand Nexxus offers the euphemism for “crushed violet pigment.” Other sites just call it “purple paint”. Custom hair care brand Formula goes a little deeper into purple shampoo using Ext Violet #2, which the Environmental Working Group (EWG) describes as a “synthetic colorant.” In other words, without a degree in chemistry, you’ll probably never know exactly what the ingredient is – but it’s known to exist in purple shampoos made by Tresemme, L’Oréal, Bumble and Bumble, and many others in water.

Does this purple-brass eradication theory make sense, and does the shampoo really work?

They seem to help, at least according to the shampoo reviews. “Totally get rid of brass in one use,” says one reviewer. Another touted “amazing results”. But at least some websites warn that overuse of purple shampoo can lead to dryness and buildup (even a little purple streaks, eek), and not all brands are equally effective. It’s also important to remember that purple shampoo doesn’t work miracles, so keep your expectations in check. In other words, do your homework before buying.

I thought making my hair grey would make life better Easier. Do I have to care about brass now?

well you don’t Have to care about anything. However, if your grays are starting to turn yellow and it bothers you for some reason, know that something purple is an option.

But don’t people sometimes dye their hair a “warm caramel color” or something? How is the brass color different?

Yes, yes, thanks – the brass concept is kind of funny, isn’t it? super subjective? Like, if your gray hair is more golden than strictly gray or silver, and you’re happy with it, why should it be a problem? For example, there are some so-called “warm-toned” dye jobs, and there are grey hairs that are considered brassy, ​​and we’re honestly struggling to tell them apart and wondering if we’re collectively on fire. (There’s also debate about whether brass is a bad thing.) But, you know, it’s true for everyone.

Is there anything else I need to know, gray hair?

Yes, this one is the most important: gray hair, brassy or otherwise, is sly. Cover it up, or leave it as it is; make it a little yellow or the color of a prison jumpsuit; use a purple, chartreuse, or burgundy shampoo. Whatever you do, know that your aging follicles have put you on the fast track to mature sexiness that only we adults can have. You can go in grey and brass if you like.Actually you want to know other What does “brass” mean? According to Merriam-Webster, it was “outrageous”. Sounds good to us.
