Is it safe to use 1 year expired shampoo? Expert advice

Have you ever found a bottle of shampoo hiding in the back of your cabinet and wondered if it’s still safe to use? Maybe it’s been a year or more since you last used it, and you’re not sure if it’s expired.

Is it safe to use 1 year expired shampoo?

The short answer is, it depends. Generally speaking, most shampoos are safe to use up to a year after their expiration date. However, there are a few factors that could impact the safety and effectiveness of the product.

Factors that can affect expired shampoo

First, it’s important to note that the expiration date on a bottle of shampoo is not a hard and fast rule. It’s more of a guideline, and the actual shelf life of the product can vary depending on a few factors:

  • Ingredients: Some ingredients in shampoo, such as natural oils, can go rancid over time, which could make the product less effective or even harmful to use.
  • Packaging: If the shampoo is stored in a clear bottle, it could be more susceptible to light damage, which could degrade the quality of the product over time.
  • Storage conditions: If the shampoo is exposed to extreme temperatures or humidity, it could affect the product’s effectiveness and safety.

Expert advice on using expired shampoo

If you’re still unsure whether it’s safe to use your expired shampoo, it’s always a good idea to consult with an expert. According to Dr. Angela Lamb, a dermatologist at Mount Sinai Hospital in New York City, “If the product looks and smells normal, and hasn’t changed in consistency, it’s probably okay to use.”

However, Dr. Lamb also advises that if you have any concerns about using an expired product, it’s always better to err on the side of caution and dispose of it.


In general, it’s safe to use 1 year expired shampoo as long as it looks, smells, and feels normal. However, factors such as ingredients, packaging, and storage conditions can impact the safety and effectiveness of the product. If you have any concerns, it’s always best to consult with an expert or dispose of the product.

Is it safe to use 2-year-old shampoo? Expert advice

Shampoo is a staple product for maintaining healthy and clean hair. However, it’s common to find a bottle of shampoo that’s been sitting in the shower for a while, and you might wonder: is it safe to use 2-year-old shampoo?

Expert advice:

According to experts, shampoo typically has a shelf life of three years. This means that using a shampoo that’s two years old should still be safe. However, there are some factors to consider before using an old bottle of shampoo.

Consider the ingredients:

The ingredients in shampoo can break down over time, which can make the shampoo less effective. For example, the active ingredients that treat dandruff or other scalp conditions may lose their potency, making the shampoo less effective. Additionally, some ingredients may become rancid or oxidize, which can cause the shampoo to smell bad or irritate the scalp.

Consider the storage:

The way you store your shampoo can also impact its shelf life. If it’s exposed to heat, humidity, or sunlight, the ingredients may break down more quickly. It’s best to store shampoo in a cool, dry place away from direct sunlight.

Consider your hair type:

If you have sensitive skin or scalp, using old shampoo may cause irritation or an allergic reaction. Additionally, if you have color-treated hair, an old bottle of shampoo may strip the color more easily, causing your hair color to fade more quickly.

The bottom line:

Using a 2-year-old bottle of shampoo is generally safe, but you should consider the ingredients, storage, and your hair type before using it. If the shampoo smells bad, looks off, or causes irritation, it’s best to toss it and get a new bottle.

How to tell if shampoo has expired?

Most shampoos have an expiration date printed on the bottle. If you can’t find an expiration date, a general rule of thumb is to use shampoo within 2-3 years of purchase. If the shampoo has changed in color, consistency, or smell, or if it causes any irritation, it’s best to toss it out.

Is it safe to use expired shampoo?

While using expired shampoo may not necessarily harm you, it’s not recommended. The risk of scalp infections or skin irritation increases with the use of expired shampoo. Additionally, expired shampoo may not clean your hair as effectively as fresh shampoo, leaving your hair feeling greasy or unclean.

How to properly dispose of expired shampoo?

The best way to dispose of expired shampoo is to simply throw it in the trash. If you’re concerned about environmental impact, you can look for shampoo recycling programs in your area.


Expired shampoo is not recommended for use due to potential risks of scalp infections or skin irritation. It’s best to check the expiration date on your shampoo bottle and dispose of it properly if it’s past its shelf life. Keeping track of the expiration dates on personal care products can help ensure that you’re using safe and effective products on your body.
