What Does Purple Shampoo Do to Brown Hair?

Purple shampoo has become a popular tool for those wanting to maintain cool tones and eliminate brassiness, but what exactly does it do to brown hair? Although traditionally recommended for blondes, purple shampoo can offer surprising benefits for brunettes too. This article dives deep into how purple shampoo works and how it affects brown hair, both natural and highlighted.


Introduction to Purple Shampoo

Purple shampoo is specifically formulated to help neutralize yellow and brassy tones in hair. Unlike regular shampoo, it contains purple pigments that counteract unwanted warm tones, leaving hair with a cooler, more vibrant appearance. While purple shampoo is often associated with blonde hair, brunettes can benefit too!

Understanding Hair Tones

Every hair color has an underlying tone, often classified as cool or warm. Brown hair can have warmer undertones, such as red or orange, which become more noticeable over time due to factors like sun exposure, styling, and mineral buildup. Purple shampoo offers a solution to help balance these tones and maintain a cooler brown shade.

The Science Behind Purple Shampoo

The concept behind purple shampoo lies in color theory. On the color wheel, purple sits opposite yellow, meaning the two colors neutralize each other. When applied to hair, the purple pigments cancel out yellow or brassy tones, bringing a refreshed look to brunettes with cooler or ashier undertones.

Why Use Purple Shampoo on Brown Hair?

While brown hair doesn’t turn “brassy” like blonde, it can develop unwanted warmth. Purple shampoo can help brown hair maintain a cool tone by muting any yellow or orange hues. This is particularly helpful for brunettes with highlights, balayage, or light brown tones, as these sections are more susceptible to warmth over time.

How Purple Shampoo Affects Brown Hair with Highlights

If you have highlights or balayage in your brown hair, purple shampoo can target those lighter sections, keeping them from turning yellow. On blonde highlights, purple shampoo works to retain a bright, cool color. For caramel or honey-colored highlights, it may soften the warmth slightly, leaving them looking richer.

Using Purple Shampoo on Light Brown vs. Dark Brown Hair

The results of purple shampoo can vary based on how light or dark your brown hair is. On light brown hair, the effects are more noticeable, as lighter hair tends to show warmth more readily. Dark brown hair may not show as dramatic a difference, but it can still benefit from a subtler cooling effect.

Pros and Cons of Purple Shampoo for Brown Hair

Pros:

  • Reduces yellow and brassy tones
  • Brightens and refreshes the overall color
  • Prolongs the life of color-treated hair

Cons:

  • Potential for a purple tint if overused
  • Might not be suitable for very dark brown or black hair
  • Can be drying if used too often

How Often Should You Use Purple Shampoo on Brown Hair?

Using purple shampoo once a week is typically sufficient for brunettes, but this can vary based on individual hair needs. If you’re dealing with excessive warmth, you may increase usage but watch for any signs of overuse, such as an ashy or purple tint.

Choosing the Right Purple Shampoo for Brown Hair

Not all purple shampoos are created equal. For brown hair, look for a product with a balanced amount of purple pigment to avoid an overly cool effect. Check for moisturizing ingredients like argan oil or keratin, as these can help prevent dryness.

Step-by-Step Guide to Using Purple Shampoo on Brown Hair

  1. Preparation: Wet your hair thoroughly and section it for even application.
  2. Application: Apply the shampoo generously, focusing on areas prone to brassiness (like highlighted sections).
  3. Leave-in Time: Let the shampoo sit for 2-5 minutes, depending on your desired level of tone correction.
  4. Rinse Thoroughly: Ensure all shampoo is rinsed out to avoid any purple residue.
  5. Condition and Style: Follow up with a hydrating conditioner to maintain softness and shine.

How to Avoid Purple Tint in Brown Hair

To prevent a purple tint, limit the leave-in time when using purple shampoo and monitor your hair’s tone. If you accidentally leave it on too long, don’t worry! You can often correct a slight tint by washing your hair with a regular clarifying shampoo.

Other Color-Depositing Shampoos for Brown Hair

Aside from purple shampoo, brunettes can consider blue or green shampoos. Blue shampoo is designed to neutralize orange tones, making it ideal for dark brunettes. Green shampoo, on the other hand, works to reduce red tones. Each shampoo has a unique purpose, so choose based on your hair’s specific needs.

Alternative Ways to Combat Brassiness in Brown Hair

If purple shampoo isn’t giving you the results you’re after, try other methods like toning treatments, purple conditioners, or professional toners. Maintaining a cooler brown color can also be achieved through regular deep conditioning and using sulfate-free products that prevent warmth from surfacing.

Conclusion

In summary, purple shampoo can be a valuable addition to a brunette’s haircare routine, especially for those with highlights or balayage. While it doesn’t produce drastic changes on dark brown hair, it can still subtly tone and enhance the overall color. Use it as part of your routine to enjoy a vibrant, cool-toned brown look.
