Yes, Matrix Brass Off Blue Shampoo does expire, much like other personal care products. Generally, the shelf life of this shampoo is about 12 to 18 months from the date of manufacturing. After this period, the product may lose its effectiveness, and the active ingredients can degrade. While using an expired product is not always dangerous, it can result in less than optimal results, such as reduced efficacy in neutralizing brassy tones in blonde or lightened hair.


Matrix Brass Off Blue Shampoo contains a blend of specialized ingredients designed to neutralize brassy tones in blonde and lightened hair. The most active components are typically colorants like Basic Blue 99 and Basic Brown 16, which work to balance out unwanted yellow or orange tones.

These are often supported by common shampoo ingredients such as sodium laureth sulfate and cocamidopropyl betaine, which work to clean the hair and help distribute the colorants evenly.

However, the presence of these active ingredients also contributes to the product’s shelf life. Over time, these colorants can degrade, and the effectiveness of surfactants like sodium laureth sulfate can diminish.

The breakdown of these ingredients is one of the reasons why Matrix Brass Off Blue Shampoo, and shampoos in general, have an expiration date.

Does Matrix Brass Off Blue Shampoo Expire?

Yes, Matrix Brass Off Blue Shampoo has a shelf life, generally ranging between 12 to 18 months from the date of manufacturing. The exact expiration date can usually be found printed on the packaging.

Manufacturers conduct stability tests to determine how long the product retains its quality and effectiveness, which includes assessing the stability of the active ingredients and preservatives.

After the expiry date, there’s no guarantee that the product will perform as intended. The shampoo’s ability to neutralize brassy tones can decrease significantly, and the textures or scents may also change.

While the shampoo may still clean your hair, it won’t deliver the promised brass-neutralizing effects, potentially leaving you with less-than-ideal hair color.

What Happens if You Use Matrix Brass Off Blue Shampoo Expired?

If you end up using Matrix Brass Off Blue Shampoo past its expiration date, the risks are generally low but the performance will likely be compromised. The main concern is reduced efficacy in toning down the brassy colors. The colorants may not be as vibrant, leading to less effective results.

Furthermore, the breakdown of active ingredients could change the pH balance of the product, which can lead to scalp irritation for some individuals. While not dangerous, using an expired product can yield suboptimal results and in rare cases, minor discomfort.

Signs of Expiration

An obvious sign that your Matrix Brass Off Blue Shampoo has expired is a change in its appearance, smell, or consistency. Over time, the shampoo may separate, develop an off odor, or even change color.

  • Separation of components in the bottle
  • Change in color
  • Unusual or off-putting odor
  • Changes in texture or consistency
  • Reduced lathering

How to Prolong the Shelf Life

To maximize the shelf life of your Matrix Brass Off Blue Shampoo, it’s important to store it properly. Like most beauty products, it should be stored in a cool, dry place, away from direct sunlight.

  1. Always seal the bottle tightly after use.
  2. Store in a cool, dark place, such as a bathroom cabinet.
  3. Avoid keeping the shampoo in environments with fluctuating temperatures.
  4. Do not dilute the shampoo with water, as this can introduce bacteria.
  5. Regularly check for signs of expiration and discontinue use if any are detected.
