Should you use purple shampoo on dry hair? Many people are saying yes but here’s a little secret – no, you shouldn’t!

Anyone with blonde hair knows how hard it can be to keep your hair a perfect blonde that’s not brassy. You leave the salon with gorgeous cool blonde only to realize it’s looking a bit more yellow and brassy just a few weeks later.

Thankfully there’s products like purple shampoo to keep your hair looking fresh! We’ve all likely used purple shampoo on wet shampoo but what about purple shampoo on dry hair?

Can you use purple shampoo on dry hair?

The short answer is you can, but you shouldn’t! You’re using purple shampoo to fix your color but your hair may actually end up looking worse than before you used it.

If you use purple shampoo on dry hair, it likely won’t be distributed evenly on your hair since your hair has different porosity levels. This basically means that your hair will absorb the purple shampoo differently depending on how porous each strand is.

Oftentimes the ends are more damaged and dry meaning they have high porosity levels and will absorb more of the purple shampoo. This will cause your color to look uneven and blotchy.

How does purple shampoo work?

You’re likely wondering how purple shampoo even works. Valid question! Purple shampoo itself has a purple tint. You’ll see this the minute you squeeze it into your hand.

This purple tint, when applied to your hair, will neutralize any shades of yellow or orange tones that is causing your blonde hair to look brassy. These yellow shades can be cause by a variety of different things – minerals in your water, chlorine, even UV rays from the sun!

You may still be wondering – but why purple? This all goes back to the color wheel you learned about in elementary school! Yellow is opposite of purple, meaning that the purple will counteract and neutralize yellow tones.

What happens when you put purple shampoo on dry hair?

Many people are saying it will quickly remove any of the yellow or gold tones from your hair rather than using it on wet hair. And while this may be true, your end result will likely be a blotchy, uneven mess rather than beautiful blonde hair.

How should you use purple shampoo?

The best way to use purple shampoo is by following the directions on your shampoo’s bottle and that typically says to start with wet hair!

Be sure to fully soak your hair from roots to ends. Some stylists even recommend putting a little conditioner on the ends since those are the most porous and will soak in the purple shampoo the most.

Don’t leave it on your hair too long since that can cause a purple hue to linger on your hair (if that happens, don’t fret – use a clarifying shampoo and it should help it come out quickly).

Rather than putting the purple shampoo in back and forth and sudsing it up like a regular shampoo, many stylists recommend put it in like you would styling product. Raking the purple shampoo will ensure that it gets distributed to all part of your hair.

How often should purple shampoo be used?

This will depend a bit on you and your hair color but start by using it once a week to begin with. If you still have brassy hair, increase it!

How long should you leave purple shampoo in?

This depends on the shampoo that you purchased and also how brassy your hair is! Always check the bottle to see what they recommend. Many recommend starting around 2-3 minutes. The longer you leave it in, the bigger difference it can make.

However, if your purple shampoo is very pigmented, you may only need a few minutes, even if your hair is super brassy! A very potent purple shampoo left in for too long can turn your hair ashy.

What happens if I leave my purple shampoo in too long?

If you leave your purple shampoo in too long and your hair now has a purple hue, simply wash your hair with a good clarifying shampoo! This will help take away the purple.

Now that you know how to properly use purple shampoo, do you know the right way to use dry shampoo? These 6 expert dry shampoo tips will show you exactly how to use dry shampoo and likely a new way or two to use it!

  1. Thank you for all your wonderful tips for styling hair etc. I found your blog when I was looking for the best styling, and rotating hair brush. I need something easier than using a round brush and hair dryer. I am having severe issues with my neck and shoulder which causes me much pain when having to hold my arm up for very long. I love all the tips on how to get volume and lasting curls. I too have straight fine blond hair. I will have to look around your blog at all the other info.
