You’ve finally achieved your dream of platinum blonde locks, but there’s one pesky problem: brassy roots. You’ve diligently used purple shampoo, but those warm tones just won’t budge. Why does purple shampoo not work on your roots? It’s a question many blonde beauties grapple with, and the answer isn‘t always straightforward.
Understanding the Science Behind Purple Shampoo
Before we delve into the reasons why purple shampoo might not be working for your roots, let’s understand the science behind it. Purple shampoo, also known as “color-depositing shampoo,” contains violet pigments that counteract the yellow and brassy tones that can develop in blonde hair.
Think of it like a color wheel – opposite colors neutralize each other. Yellow and violet are opposite on the color wheel, and purple shampoo uses this principle to tone down brassiness.
Why Your Roots Might Be Resistant to Purple Shampoo
Now, let’s address the elephant in the room: why your roots might be stubbornly clinging to those brassy hues. Here are some common culprits:
1. Your Roots Are Naturally Warm
Some individuals have naturally warm undertones in their hair. This means their hair pigment contains more yellow and red pigments, making it more susceptible to brassiness. Even if your ends are a cool blonde, your roots may inherently have a warmer base, making it harder to neutralize the brassiness with purple shampoo alone.
2. Your Hair Has Been Exposed to Harsh Treatments
If you’ve recently bleached your hair, used a permanent hair dye, or even subjected your hair to excessive heat styling, it can lead to damage and porosity. This damage can make your hair more porous, allowing pigment to penetrate and deposit more easily. However, it can also make it harder for the purple pigments to adhere to your roots, especially if the damage is concentrated at the roots.
3. You’re Not Using Purple Shampoo Correctly
Believe it or not, the way you use purple shampoo can significantly impact its effectiveness. Here are some common mistakes:
- Using it too often: While purple shampoo is effective, using it too frequently can actually make your hair look dull and ashy. Aim to use it 1-2 times a week, depending on your hair’s brassiness levels.
- Leaving it on for too long: Leaving purple shampoo on for an extended period can lead to an uneven color distribution, making your hair look purple rather than toned. Follow the instructions on the bottle and don’t leave it on for more than 5 minutes.
- Using it on dry hair: Purple shampoo is most effective when applied to damp hair. Applying it to dry hair can result in uneven distribution and potentially lead to dryness.
4. Your Purple Shampoo Is Not Strong Enough
The strength of purple shampoo varies depending on the brand and formula. If your purple shampoo is not strong enough to counteract the brassiness in your roots, it may not be effective. Consider trying a different brand or a purple shampoo with a higher concentration of violet pigments.
What To Do When Purple Shampoo Doesn’t Work on Your Roots
So, what can you do if purple shampoo isn‘t cutting it for your roots? Don’t despair! There are other solutions to achieve your desired cool blonde:
1. Consult a Hair Colorist
If you’re struggling with persistent brassiness, a professional hair colorist can be your savior. They can assess your hair’s condition, color history, and desired shade and recommend the best course of action. This may include:
- Toning: A hair colorist can use a toner to neutralize the brassiness in your roots, leaving you with a more consistent blonde shade.
- Glazing: A glaze is a semi-permanent color treatment that can add shine and subtly tone down brassiness.
- Color Correction: In more severe cases, a color correction treatment may be necessary to completely remove unwanted brassy tones and achieve your desired shade.
2. Try a Purple Toner
Purple toners are more concentrated than purple shampoos and can be used to target specific areas of brassiness. They typically come in a gel or cream formula and are applied to damp hair for a set amount of time before rinsing.
3. Use a Color-Depositing Conditioner
Color-depositing conditioners work similarly to purple shampoo but are less harsh and can be used more frequently. They deposit subtle amounts of color over time, helping to gradually neutralize brassiness.
4. Embrace the Brass
Sometimes, the best solution is to embrace the brass! If you’re finding it difficult to completely eliminate brassiness, consider styling your hair in a way that plays up the warm tones. For example, you can try a beachy wave or a messy bun to create a more effortless, natural look.
Beyond Purple Shampoo: Maintaining Your Blonde
Once you’ve achieved your desired shade of blonde, it’s important to maintain it. Here are some tips:
- Use a color-safe shampoo and conditioner: These products are designed to prevent fading and brassiness, keeping your blonde looking fresh and vibrant.
- Avoid heat styling: Excessive heat styling can damage your hair and lead to brassiness. Try to air dry your hair as often as possible.
- Protect your hair from the sun: UV rays can cause your blonde hair to fade and become brassy. Wear a hat or use a hair product with UV protection when spending time outdoors.
- Get regular trims: Trimming your hair regularly will help to remove split ends and prevent further damage, which can contribute to brassiness.
The Final Word: A Balanced Approach
While purple shampoo is a valuable tool for combating brassiness, it’s important to remember that it’s not a one-size-fits-all solution. The key to achieving and maintaining a beautiful, cool blonde is a balanced approach that addresses the specific needs of your hair. Whether you choose to embrace the brass, seek professional help, or try out different products, remember that there’s no single “right” answer. Experiment, find what works best for you, and embrace the journey to your dream blonde!
