Hairstyle trends are forever changing, but there are always people who want to take the plunge and go blonde, bright blonde! If you’ve gone blonde, there’s always that fear of waking up and looking in the mirror, only to find that your color isn’t quite the same as it was when you went to sleep the night before. You can try to forget the problem by avoiding the mirror altogether, but eventually, you’ll see your hair. Something that occurs SO often and is a major problem for all you blondes is finding brassy tones creeping up when you least expect it. Well, I’m about to share with you some brassy hair tips and tricks that will save you tons of money, frustration, and anxiety!

What Causes Brassy Hair?

Being a woman has its ups and downs. Whether it’s getting a painful pimple or a bad hair day, womanhood is tough. But nothing quite compares to the horror of brassy blonde hair. Brassiness is probably a blonde’s worst nightmare. Brassiness can be caused by quite a few things like hair care products, your shower water, and your natural hair color. When this occurs, many people who don’t know what to do run to a hairstylist at their nearest salon and spend a fortune on redying their hair. Haircare ain’t no joke when it comes to lightening your natural hair color.

While this is a good solution to a devastating problem, it can cost a fortune and let’s be honest… who has the time? If I were to run to my stylist every time a bit of brass crept up in my hair, I would most probably be living on the streets, along with so many other blondes! So here’s what everyone is wondering: what exactly can be done that doesn’t entail running to the salon? Isn’t there something that can be done from home that can at least help a little bit? HAVE NO FEAR. Take a look below.

1. Purple Shampoo For Brassy Hair

If you’re blonde, then I don’t need to explain to you what purple shampoo is and how it works. But I will explain it to everyone else. Since violet and yellow are opposite one another on the color wheel, they cancel each other out. So if you have warm tones in your blonde dyed hair, you’ll need some purple. Go out and get yourself a bottle of any kind of purple or violet sulfate-free shampoo and I PROMISE you that it will be a great solution to your brassy problem. It’s like a magic shampoo, actually. People say that it takes a few times until you can see a difference, but I was actually able to see a difference after only using it once. It works like a charm. If you aren’t a blonde, purple shampoo works by neutralizing your brassy tones. The purple pigment is distributed throughout your hair to cancel out the red tones and yellow tones and make your blue undertones higher. It brightens the blonde by restoring your hair to its former, cool blonde. You can bid your warm tones farewell. 

There are plenty of different kinds of purple shampoos on the market, so don’t be overwhelmed. You basically just need to read up on all the products and buy whichever purple shampoo sounds fitting for your specific hair type. You should aim for one that works as a toner. Toning shampoos are very popular. Toning is necessary to neutralize brassiness. The shampoo should also be able to raise your hair cuticles to give your hair more volume. Although all of the shampoos are more or less the same deal, they are each formulated for specific types of hair. For example – some are better for ombre hair, some are better for highlights, balayage, or completely dyed hair. You can even use a purple conditioner. Make sure to get one that’s specifically color safe!

2. At-Home Brass Banisher

Maintaining blonde hues needn’t be too hard.

Purple Shampoo is a product that people have mixed opinions about. Some people will say how great it is, and other people will say it literally did nothing. It’s a great DIY method than running to your salon. I personally found this product to work for me at times and at other times I didn’t see much of a difference, but I guess it really depends on what kind of hair you have and how you use the product. How you apply it makes a difference. Before you put the purple shampoo in your hair, you should rinse it with warm water. The warm water will cause your hair shaft to expand which will allow for more purple pigment to penetrate. After you apply the shampoo, you should let it sit for one to five minutes before rinsing it out. You should then rinse your hair with cold water, which will close the hair shaft. This will seal in the color and leave it protected.

Purple shampoo seems to be very popular. A lot of big-name salons promote it. It’s said to be safe to use in between colorings and is ammonia-free. There are also purple hair masks and other hair products for a deeper treatment. It seems that a lot of people decide to try this product because they don’t have the time or money to get to the salon and get their hair toned. So why not try it yourself if you can? That’s how I see it. If it works, great! If not, then you didn’t really lose anything besides a few bucks.

3. Shower Filters For Brassy Hair

Great hair starts in the shower.

This is something that I just recently heard about. People are familiar with water filters for the sink, but not many people have heard about shower filters! If you’re someone with color-sensitive hair then this is definitely a product to invest in. The product isn’t that well known, so not that many companies have come out with it. There are a few different companies out there that seem to sell a solid shower filter. Shower filters work by removing chemicals from your shower water. Unfiltered water has a lot of mineral deposits. Therefore it can cause unwanted warm tones, like orange tones if you naturally have brunette hair or red hair. It can’t only damage your hair color but it can also cause skin dryness, irritation, and even life-threatening diseases.

The shower filter neutralizes the chemicals. Chemicals like chlorine and iron are found in shower water and are probably not the nicest stuff to absorb. They can also make color fade, look dull, and effect the saturation. Chlorine is an enemy to hair, especially color-treated hair. It strips hair of its natural oils, leaving it frizzy, dry. It can also make your scalp scaly and irritated. Iron, specifically, can add to those pesky, reddish, brassy tones. Washing your hair in filtered water will make your highlights and color last significantly longer than if you weren’t.

4. Clear Oils For Brassy Hair

As you can see the products you put in your hair will actually affect its hue. If purple shampoo can prevent your hair from going brassy, then you should avoid anything else that might make you go from blonde to orange. This applies to all products you use before, during, and even after your shower. If the product is purple or clear, your hair is in the clear as well.

Most people use some kind of oil on their hair before blow-drying. If this is something that you do, check to see if your oil of choice is colored. Happens to be, that a lot of popular oils that are on the market are brown in color, which can ultimately affect the color of your hair. That’s not bad if your hair is naturally dark, but if you’re trying to prevent brassy hair, you may want to start using a clear oil. The color in the oil can slowly alter the tone of your blonde. Moroccan oil is a yellowish-orange and will therefore over time turn your colored-hair, yep you guessed it, a yellowish-orange. If you like to use oil, you can try coconut oil or pure argan oil. Both are clear and won’t discolor your blonde locks. You should also avoid direct sunlight in the beginning since the UV rays bring out the warmer tones in your hair.

5. Bleaching Brassy Hair Breakdown

If your natural hair is rich in red pigment you will have to bleach it in order to maintain the blonde shade you’ve put so much effort into getting. The underlying pigment in dark brown hair or black hair is what causes brassiness in the first place. A colorist has to lift your natural color and then proceed to use hair dye to get it to the desired color. A lot of women with dark hair are wondering how to get blonde hair without bleaching, but unfortunately, it’s not possible. If the color isn’t lifted enough, your hair will end up with brassy tones. In order for the new blonde hair to last and not instantly go brassy, you’ll need to strip as much of its natural pigment as possible.

Call it bleach or call it a lightener – it pretty much does the same thing! Cheer up, because there are ways to minimize the risks of damaging your hair. You should stick with professional products. There’s a reason people pay a fortune to go to a salon with professionals, it’s because their products work. You don’t need to be the guinea pig and try new ideas or products that not many other people have used. Use products that are trusted with positive reviews. You should also never let products stay on your hair longer than required. Each product, like hair masks, comes with instructions. Read them and follow them! Once you get your perfect shade, only bleach the roots. If you bleach anything else it will mess everything up, and the shade you used to love will never be the same.
