Hair serums are an essential part of a hair care routine, especially for those with frizzy, curly, or untameable hair. However, like any other beauty product, hair serums have a shelf life.
Most people might not think about checking the expiration date of their hair serum, but it’s essential to understand that they can expire and become ineffective.
What Happens When Hair Serum Expired?
When hair serum expires, it can lose its effectiveness and even cause more damage to your hair. The ingredients in expired hair serum may break down and cause your hair to become greasy, sticky, or even lead to hair loss. Using expired hair serum can also lead to scalp irritation, breakouts, or allergic reactions.
Signs That Your Hair Serum Has Expired
It’s essential to know the signs of an expired hair serum to avoid using it. The first sign of expired hair serum is a change in texture or color. If the serum is cloudy, discolored, or has separated, then it’s time to toss it out. Another sign is a change in smell. If your hair serum smells off or different from when you first bought it, then it’s best to discard it.

How Long Does Hair Serum Last?
The shelf life of hair serum depends on the brand, formulation, and storage conditions. Typically, hair serums last up to two years from the date of production. However, it’s always best to check the expiration date on the bottle to be sure. If the bottle is already opened, it could become less effective after six months, so it’s best to use it up within that time frame.
How to Store Your Hair Serum Properly
To extend the shelf life of your hair serum, store it in a cool, dry place, away from direct sunlight and heat. Avoid keeping it in the bathroom, where it can be exposed to moisture and humidity. Make sure to keep the lid tightly closed when not in use. Always check the label for specific storage instructions.
Can You Use Expired Hair Serum?
It’s not recommended to use expired hair serum as it can lead to adverse effects. Expired hair serum can cause your hair to become greasy or even lead to hair loss. Additionally, it can cause scalp irritation, breakouts, or allergic reactions. It’s best to discard expired hair serum and purchase a new one.
Tips for Extending the Life of Your Hair Serum
To make your hair serum last longer, use the recommended amount and use it only when necessary. Not using too much hair serum will also prevent build-up and save you from having to wash your hair frequently. Also, avoid storing your hair serum in the bathroom or any humid place. Lastly, always keep the lid tightly closed when not in use.
When to Replace Your Hair Serum
It’s best to replace your hair serum every two years, even if it hasn’t expired. If you notice a change in the smell, color, or texture of your hair serum, then it’s time to discard it. Using an expired or ineffective hair serum can cause more damage than good, so it’s best to invest in a new one.
