What Happens If I Wash My Hair With Expired Shampoo?
Expired shampoo can contain harmful bacteria and other toxic substances that can damage hair and scalp. The chemicals in expired shampoo can change, making them more harsh and damaging to the hair and scalp.
This can lead to irritation, dryness, and flaking of the scalp, which can in turn cause hair loss. When the scalp is damaged, it can become inflamed and infected, which can also contribute to hair loss.
Possible hair loss triggers from expired shampoo
One of the primary triggers for hair loss from expired shampoo is the presence of harsh chemicals. These chemicals can strip the hair of its natural oils and nutrients, leaving it dry, brittle, and prone to breakage.
Additionally, the buildup of bacteria and other impurities on the scalp can clog the hair follicles, causing them to become blocked and preventing hair growth
How long expired shampoo can be used before causing hair loss
The length of time that expired shampoo can be used before causing hair loss varies depending on several factors, including the type of shampoo, the ingredients, and the storage conditions.
Generally, it is recommended to replace shampoo every 6-12 months, as the effectiveness of the product decreases over time. If you are using expired shampoo and notice any signs of hair loss or scalp irritation, it is important to stop using it immediately and switch to a fresh product.
The dangers of using expired shampoo
Expired shampoo can undergo chemical changes that can make it harmful to use. According to the FDA, some of the common changes that occur in expired shampoo include the breakdown of preservatives and the formation of harmful microorganisms such as bacteria and mold.
This can make the shampoo less effective and more harmful to the hair and scalp, potentially causing skin irritation and infections.

How to determine if your shampoo has expired
Most shampoos will have an expiration date listed on the packaging, which is the date after which the product is no longer considered safe to use.
It is important to note that this date is not a guarantee of the product’s effectiveness, but rather a suggestion of when it should be replaced. If the shampoo does not have an expiration date, you can use the “period after opening” symbol, which is a small jar with an open lid and a number inside, to determine the recommended shelf life of the product.
Checking the appearance and smell of shampoo
If there is no expiration date or “period after opening” symbol, you can also check the appearance and smell of the shampoo to determine if it has expired.
Expired shampoo may have a rancid odor or an unusual appearance, such as a change in color or texture. If the shampoo smells off or has changed in appearance, it is best to discard it and replace it with a fresh product.[Source]
Storing shampoo properly to extend its shelf life
Proper storage of shampoo can help extend its shelf life and prevent it from becoming expired. It is best to store shampoo in a cool, dry place, away from direct sunlight and heat sources.
Keeping the lid tightly closed and avoiding contamination from dirty hands or other impurities can also help prevent the shampoo from becoming expired.
