Most people probably don’t think about whether or not hair toner expires, but the fact is that it does. Just like any other beauty product, hair toner has a shelf life.
But what is the expiration date on hair toner, and how can you tell if it’s gone bad? In this article, we’ll answer those questions and more.
Read on to learn everything you need to know about hair toner expiration dates.
What is a Hair Toner?
A hair toner is a demi-permanent hair color that can enhance, change, or deepen the existing color of your hair. So, in short, it’s a way to temporarily change your hair color at home.
Most toners are used after bleaching your hair in order to achieve the desired shade. For example, if you want to go from blonde to platinum blonde, you would first bleach your hair and then use a toner to get the exact shade you want.
Toners can also be used to refresh faded hair color or to give your hair a little extra shine.
How Long Does Hair Toner Last on Hair?
Hair toner generally lasts about 4-6 weeks, although this can vary depending on the type of toner you use and how often you wash your hair.
If you want your hair toner to last as long as possible, the best thing to do is to avoid washing your hair too often. Every time you wash your hair, some of the colors will fade. So, if you can, try to stick to washing your hair every other day or every third day.
When it comes to shampooing, be sure to use a color-safe shampoo and conditioner that won’t strip away the toner. And, avoid using hot water when washing your hair, as this can also cause the color to fade. If you follow these tips, your hair toner should last for several weeks.
Does Hair Toner Expire?
Yes, hair toner does expire. The expiration date will depend on the brand and type of toner you use, but most toners will last for about 2 years when stored properly.
To find the expiration date, simply look for the “PAO” (Period After Opening) symbol on the packaging. This symbol is a small jar with a number inside of it, and the number indicates how many months the product is good for after opening.
So, if you see a PAO symbol that says “6M,” that means the product is good for 6 months after opening. Once a hair toner expires, it’s best to throw it away and get a new one. Using an expired toner could cause irritation or other skin problems.
How Can You Tell if Hair Toner is Expired?
There are a few indicators that indicate when hair toner has gone rancid:
Look for the expiration date on the bottle first. It’s probably time to get rid of it if the bottle’s expiration date has passed. The consistency may also be an indication.
Another way to tell if hair toner has expired is by doing a patch test. Simply apply a small amount of the toner to your skin and wait 24 hours to see if there is any irritation. If you experience any redness, swelling, or other irritation, it’s best to discard the toner.
Finally, if the scent has altered or does not smell good, it’s very likely that the hair toner is no longer effective.
How Long Does Hair Toner Last Once Open?
In general, it’s best to use hair toner within 6 months of opening it. After that, it’s probably time to buy a new bottle.
How to Store Hair Toner
Proper storage is important for keeping hair toner fresh and preventing it from expiring too soon. Here are a few tips for storing hair toner:
- Store hair toner in a cool, dark place: sunlight and heat can cause hair toner to degrade faster, so it’s best to store it in a cool, dark place like a cabinet or drawer.
- Do not freeze hair toner: freezing can also damage hair toner and make it less effective.
- Keep the lid tight: be sure to close the lid tightly after each use to prevent the toner from drying out.
Following these storage tips will help extend the shelf life of your hair toner.
Can You Extend the Shelf Life of Hair Toner?
Unfortunately, there’s no surefire way to extend the shelf life of hair toner. However, there are a few things you can do to help it last a little longer.
- First, be sure to store hair toner in a cool, dark place. Heat and light can cause the chemicals in hair toner to break down, making it less effective.
- Second, don’t open the hair toner bottle more than you need to. Every time you open it, you expose the toner to air and light, which can hasten its expiration.
- Third, try to use hair toner within six months of opening it. After that, it’s likely to be less effective.
If you use these instructions, you may be able to get a few more months out of your hair toner. However, it’s preferable to utilize it before it expires.
Can You Use Expired Hair Toner?
It’s not recommended to use expired hair toner. The reason is that expired hair toner may not work as well and it could even cause irritation. So, if you’re not sure, it’s usually better to err on the side of caution and toss it out. Fresh hair toner is always the best option for obtaining excellent outcomes.
Does Expired Hair Toner Damage Your Hair?
Expired hair toner may not work as well, but it’s unlikely to damage your hair. However, if you experience any irritation after using expired hair toner, discontinue use immediately and consult a doctor if necessary.
In general, it’s always best to use fresh, unexpired products whenever possible. However, if you must use expired hair toner, do a patch test on a small area of skin first to check for any adverse reaction.
