Purple Shampoo on Brown Hair: Can You Use It & What Happens?

Thinking about using purple shampoo on your brown hair? You’re not alone! Many brunettes are curious about how this toning product, typically associated with blonde hair, can impact their darker locks. The short answer is yes, you can use purple shampoo on brown hair, but the results and the way you use it will be different than if you had blonde hair. This comprehensive guide will delve into the science behind purple shampoo, how it interacts with brown hair, the potential benefits and drawbacks, and how to use it effectively. We’ll also address common concerns and provide expert tips to ensure you achieve the desired results without any unwanted surprises.

Understanding Purple Shampoo and Color Theory

Purple shampoo is formulated with violet pigments that counteract brassy, yellow, or orange tones in hair. This is based on the principles of color theory, where purple and yellow are opposite each other on the color wheel. When purple pigment is deposited onto yellow tones, it neutralizes them, resulting in a cooler, more balanced color. It’s primarily designed to brighten and maintain blonde, platinum, or gray hair, preventing it from becoming dull or brassy.

However, brown hair can also develop unwanted warm tones. Sun exposure, hard water, and certain hair products can contribute to brassiness in brown hair, making it appear reddish or orange. The key question is whether purple shampoo can effectively neutralize these tones in darker hair without causing undesirable effects.

The Science Behind the Shampoo

Purple shampoo works by depositing a small amount of purple pigment onto the hair shaft. The pigment adheres to the hair cuticle, neutralizing the underlying warm tones. The effectiveness of the shampoo depends on several factors, including the concentration of purple pigment, the porosity of the hair, and the length of time the shampoo is left on the hair. For blonde hair, the effect is usually a brightening and toning one. But what happens on brown hair?

Can Purple Shampoo Actually Help Brown Hair?

The answer is a qualified yes. Purple shampoo can help neutralize brassy tones in brown hair, but the results are typically more subtle than on blonde hair. Because brown hair has a darker base, the purple pigment is less likely to dramatically alter the overall color. Instead, it works to subtly cool down the warm tones, resulting in a richer, more balanced brown.

The effectiveness depends heavily on the shade of brown hair. Lighter shades of brown, such as light brunette or dark blonde, will see a more noticeable difference compared to darker shades. Very dark brown or black hair may not show any visible change after using purple shampoo.

Potential Benefits of Using Purple Shampoo on Brown Hair:

Neutralizing Brassiness: Reduces unwanted red or orange tones.
Adding Depth and Richness: Can enhance the cool tones in brown hair, making it appear more vibrant.
Extending the Life of Brown Hair Color: Helps maintain the desired tone between salon visits.

Potential Drawbacks:

Minimal Impact on Darker Shades: May not produce noticeable results on very dark brown or black hair.
Risk of Over-Toning: Leaving the shampoo on for too long can result in a purple or ashy tint, especially on lighter brown hair.
Dryness: Some purple shampoos can be drying, particularly if they contain sulfates.

How to Use Purple Shampoo on Brown Hair: A Step-by-Step Guide

To maximize the benefits of purple shampoo and minimize the risks, follow these steps:

Choose the Right Shampoo: Look for a purple shampoo specifically formulated for brown hair. These shampoos typically have a lower concentration of purple pigment compared to those designed for blonde hair. Brands like Joico, Redken, and Matrix offer purple shampoos that are suitable for brunettes.
Wet Your Hair: Thoroughly wet your hair with lukewarm water.
Apply the Shampoo: Apply a generous amount of purple shampoo to your hair, focusing on the areas where you notice the most brassiness.
Massage Gently: Gently massage the shampoo into your hair and scalp, ensuring even distribution.
Wait a Few Minutes: This is the most crucial step. For brown hair, start with a shorter processing time, such as 2-3 minutes. You can gradually increase the time in subsequent washes if needed. Leaving it on for too long can lead to purple or ashy tones.
Rinse Thoroughly: Rinse your hair thoroughly with cool water until all the shampoo is removed.
Condition Your Hair: Purple shampoo can be drying, so it’s essential to follow up with a moisturizing conditioner. Leave the conditioner on for a few minutes before rinsing.
Repeat as Needed: Use purple shampoo once or twice a week, depending on the level of brassiness and your hair’s response to the product.

Expert Tips for Using Purple Shampoo on Brown Hair

To get the best results and avoid common pitfalls, consider these expert tips:

Do a Strand Test: Before applying purple shampoo to your entire head, test it on a small, inconspicuous section of your hair to see how it reacts.
Dilute the Shampoo: If you’re concerned about over-toning, dilute the purple shampoo with your regular shampoo. This will reduce the concentration of purple pigment and minimize the risk of unwanted tones.
Use a Deep Conditioner: Incorporate a deep conditioning treatment into your hair care routine to combat any dryness caused by the purple shampoo.
Adjust the Processing Time: Pay close attention to how your hair responds to the purple shampoo and adjust the processing time accordingly. If you notice purple or ashy tones, reduce the time in future washes.
Consider a Purple Mask: If you prefer a more intensive treatment, consider using a purple hair mask instead of a shampoo. Masks typically have a higher concentration of pigment and can provide more noticeable results.
Consult a Professional: If you’re unsure about using purple shampoo on your brown hair, consult with a professional hairstylist. They can assess your hair color and texture and recommend the best products and techniques for achieving your desired results.

Product Spotlight: Olaplex No. 4P Blonde Enhancer Toning Shampoo

While marketed as a blonde enhancer, Olaplex No. 4P is a popular choice for brunettes looking to combat brassiness. It stands out due to its incorporation of Olaplex’s signature bond-building technology, which helps to repair and strengthen damaged hair while also toning unwanted warmth.

Olaplex No. 4P works by depositing purple pigment to neutralize yellow and orange tones. However, it also contains ingredients that help to rebuild broken disulfide bonds in the hair, which are responsible for hair strength and elasticity. This makes it a gentler and more nourishing option compared to some other purple shampoos on the market.

Users consistently report that their hair feels stronger and healthier after using Olaplex No. 4P.
