  2. You must always store the developer in a cool place that is away from direct sunlight and moisture.

Before you begin to understand if the developer gets bad, let’s quickly check the difference between developer and developer cream.

How to tell if the developer is bad?

In most developers, you won’t see the expiry date printed on the pack. However, it is because every standard developer has a 3 years expiry period which manufacturers assume you are aware of.

Another reason for the expiry date not mentioned is because you are expected to use it as soon as you open it. In short, a closed developer lasts for three years and an opened developer lasts for six months only.

The easiest way to check if the developer is expired is by smelling it. Bring the pack close to your nose and check if any weird scent or smell comes.

If you feel some sort of smell that feels weird, throw it immediately. It is most likely that your developer has expired.

Do not smell it too close as the chemicals inside may be toxic to health. You may have noticed a strong smell at the time of application due to the chemicals involved.

Method 2:

Another way to check is the smoothness of your liquid developer. If your developer seems more liquid than the last time you used it, your developer maybe in a bad condition.

Method 3:

If your liquid developer is showing a yellowish color, there is a possibility that it was exposed to sun or heat. You mustn’t use it.

Method 4:

If your cream developer is sticky to your hands it’s because the developer has expired. Avoid using it and dispose it off immediately.
