The Science Behind Purple Shampoos: How Matrix’s Formula Works to Counteract Brassiness

Purple shampoos have become increasingly popular in the hair care industry, especially among individuals with blonde or silver hair. These shampoos are formulated to counteract brassiness, which is a common problem faced by those with lighter hair colors. One such popular purple shampoo is the Matrix Total Results So Silver Purple Shampoo, known for its effective brassiness-fighting abilities. In this article, we will delve into the science behind purple shampoos and explore how Matrix’s formula works to combat unwanted warm tones and maintain vibrant, cool hues.

1. How do purple shampoos work?
Purple shampoos work on the principle of color theory. According to this theory, colors that are opposite each other on the color wheel cancel each other out when combined. Since purple is opposite to yellow on the color wheel, using a purple shampoo helps neutralize any yellow or brassy tones in the hair.

2. What causes brassiness in blonde or silver hair?
Brassiness occurs when the cool tones in blonde or silver hair start to fade, revealing warmer undertones. It can be caused by various factors, including exposure to sunlight, chemicals in hair products, and even minerals present in tap water.

3. How does Matrix’s purple shampoo counteract brassiness?
Matrix’s Total Results So Silver Purple Shampoo is specifically formulated with violet pigments. These pigments help neutralize the unwanted warm tones, enhancing the cool shades in the hair. The shampoo works by depositing a small amount of violet pigment on the hair cuticle, toning down any yellow or orange hues.

4. Does Matrix’s purple shampoo work on all hair colors?
Matrix’s purple shampoo works best on blonde or silver hair, as these hair colors tend to be more prone to brassiness. However, it can also be used on other hair colors that are experiencing unwanted warmth, such as brunettes with highlights or ombre styles.

5. Should purple shampoo be used every day?
Purple shampoo should not be used every day unless specified by the product instructions. Overuse can lead to an excessive violet tone in the hair, giving it a purple tinge. It is recommended to use it once or twice a week, depending on how frequently brassiness occurs.

6. How long should purple shampoo be left on the hair?
The duration to leave purple shampoo on the hair may vary depending on the brand and the desired results. Generally, it is advised to leave it on for 3-5 minutes before rinsing. However, some purple shampoos can be left on for up to 10 minutes for a more intense toning effect. It is essential to follow the instructions mentioned on the product packaging.

7. Can purple shampoo replace regular shampoo?
Purple shampoo is not meant to replace regular shampoo. Its primary purpose is to combat brassy tones and maintain the desired cool shade. It is recommended to use a regular shampoo to cleanse the hair and scalp before applying purple shampoo for optimal results.

8. Is it necessary to follow up with a conditioner after using purple shampoo?
Yes, it is crucial to follow up with a conditioner after using purple shampoo. Purple shampoos can sometimes leave the hair feeling dry, as they tend to have a higher cleansing power. Using a conditioner helps restore moisture and keeps the hair hydrated and manageable.

9. Can purple shampoo be used on color-treated hair?
Yes, purple shampoo can also be used on color-treated hair. In fact, it is often recommended for individuals with blonde dyed hair to help maintain the cool tones and prevent color from fading into brassiness.

10. Will purple shampoo lighten darker hair?
Purple shampoo does not lighten darker hair. Its main purpose is toning, which means it helps counteract brassiness but does not lift the existing hair color. It is not suitable for those seeking a lightening effect on their dark hair.

11. How often should purple shampoo be used?
The frequency of using purple shampoo varies based on individual needs. It is generally recommended to use it once or twice a week to maintain the desired cool tones. However, some may need to use it more frequently, while others may find it effective to use it less often.

12. What other hair care products can be used in combination with purple shampoo?
To enhance the toning effects of purple shampoo, using a purple conditioner or mask can be beneficial. These products help prolong the cool hues and provide added moisture to the hair. Additionally, using hair serums or oils specifically formulated for color-treated hair can provide further protection and shine.

13. Are there any precautions or side effects associated with using purple shampoo?
While purple shampoos are generally safe to use, overuse or leaving the product on for an extended period can lead to a purple cast or stain on the hair. It is crucial to follow the instructions provided on the product packaging and avoid leaving the shampoo on for too long to prevent any unwanted pigmentation.

14. Can purple shampoo be used on natural gray hair?
Yes, purple shampoo can be used on natural gray hair to prevent yellowing and maintain a cool, silvery shade. Since gray hair can also be prone to becoming brassy or dull over time, using purple shampoo helps bring back vibrancy and contrast.

15. How long does it take to see results with purple shampoo?
Results can vary depending on the individual’s hair type and the severity of brassiness. Some people may notice a significant difference after just one use, while others may require a few washes to see the desired results. Consistent use over time usually provides more noticeable and long-lasting effects.

16. Can purple shampoo be used on dry or damaged hair?
Yes, purple shampoo can be used on dry or damaged hair, but it may further contribute to dryness. It is advisable to use a moisturizing conditioner or a deep conditioning treatment afterward to restore hydration and minimize any potential damage.

17. Can purple shampoo be used on hair extensions or wigs?
Purple shampoo can be used on human hair extensions or wigs, provided that they have not been color-treated. However, caution should be exercised when using purple shampoo on synthetic extensions or wigs, as they might react differently to the violet pigments.

18. Can purple shampoo be used on naturally red hair?
Purple shampoo is not typically recommended for naturally red hair, as it has a higher chance of neutralizing or dulling the vibrant red tones. If attempting to counteract brassiness in red hair, it is safer to choose a color-specific toning product formulated for red shades.

19. Can purple shampoo be used on men’s hair?
Yes, purple shampoo can be used on men’s hair to counteract brassiness, especially if they have blonde or silver hair. The same principles apply to all hair genders when it comes to toning and neutralizing unwanted warm tones.

20. Can purple shampoo be used on children’s hair?
Purple shampoo is generally safe for use on children’s hair, but it is advised to consult a pediatrician or hairstylist before introducing any new hair care product. Children’s hair tends to be more delicate, and it is essential to ensure the formula is gentle and suitable for their specific needs.

In conclusion, purple shampoos have revolutionized the way we tackle brassiness in lighter hair colors. Matrix’s Total Results So Silver Purple Shampoo, with its violet pigments, provides an effective solution to maintaining vibrant, cool shades by neutralizing unwanted warm tones.
