Yes, hair conditioner does go bad.
Like many cosmetic products, hair conditioner has a limited shelf life. The longevity of your conditioner depends on whether it has been opened or not.
Shelf Life of Hair Conditioner
Here’s a breakdown of how long you can expect your conditioner to last:
| Condition | Shelf Life |
|---|---|
| Unopened Bottle | 2 to 3 years |
| Opened Bottle | Up to 18 months |
According to our references, the type of conditioner, whether it's a deep conditioner, leave-in conditioner, or a moisturizing conditioner, does not impact its shelf life. All types of conditioner, when unopened, last for two to three years. Once opened, they should be used within 18 months.
How to Tell if Conditioner Has Gone Bad
Even if your conditioner is within its stated shelf life, it can still go bad if not stored correctly or if the container is damaged. Here are some signs that your conditioner may be past its prime:
- Changes in consistency: If the conditioner becomes overly thick or thin.
- Changes in color or scent: If the color appears dull or the scent is different from what it should be.
- Separation: If the conditioner separates and the oil and water no longer mix.
Tips for Extending the Life of Your Conditioner
Here are some tips to make your hair conditioner last longer:
- Store in a Cool, Dry Place: Avoid keeping your conditioner in the hot or humid bathroom.
- Close the Cap Tightly: This prevents air and bacteria from getting into the container.
- Don’t Add Water: Adding water to thin out conditioner can introduce bacteria.
- Use Clean Hands: Dirty hands can introduce bacteria into the conditioner.
