Do you know when to toss your products out? Most people don’t and it could cause you both your skin and your hair. You should always be conscious of how long you’ve had each and every product because believe it or not, these babies do have a shelf life and they do expire.
Hair creams such as gels and mousses, especially products that come in a container are good for about 18 months after they have been opened. Anything after that, you should toss out. Unopened products have a shelf-life of about three years.
To maximize usage, pick up products that are contained in cans as they last longer. Product such as aerosols are sealed and don’t run the risk of contamination or dilution so their shelf life is not shortened once opened. To fully take advantage of shelf life, keep products you’re not using in a cool, dark place.
The best way to tell when a product is expired is by its texture and scent. Creams will usually separate or curdle. A dark yellow color is another sign that a product is past its prime. Just to be safe, you should toss out anything after 6 months. Pricier products usually have expiration dates on the back.
But even if you’re not keeping track of the way every product in your bathroom cabinet originally smelled and looked, you should still be able to tell. Malodors are typically very different than what a product’s fragrance might have smelled like — if the smell is unpleasant, such as a dirty or sour smell, it’s a good indication. The good news is that expired products aren’t harmful to hair, with only a small chance of scalp irritation.
