Understanding Hair Bleach
1. What is Hair Bleach?
A chemical solution called hair bleach is used to make hair appear lighter than it naturally is. It functions by entering the hair shaft and dissolving the pigment called melanin, which gives hair its colour. A strong and efficient tool for highlights, balayage, or a whole-body lighter look is bleach.
2. Key Components
- Active Ingredients: The primary active ingredients in hair bleach are typically hydrogen peroxide and ammonia. These chemicals work together to oxidise the melanin and lift the colour of hair.

1. Shelf Life of Hair Bleach
It’s important to understand that hair bleach has a shelf life in order to guarantee both safety and the best possible outcomes. Unopened hair bleach typically has a one- to one-and-a-half-year shelf life after the date of production.
2. Expiry Signs
- Change in Smell: If the bleach has a strong, unpleasant odour that is different from its usual scent, it may indicate that the product has expired.
- Change in Colour: Any noticeable change in the colour of the bleach, such as darkening or discoloration, suggests that it may be past its prime.
- Ineffectiveness: Expired bleach may not work as effectively in lightening the hair. If you notice that the bleach is not producing the desired results, it might be a sign of expiration.
Best Practices for Using Hair Bleach
1. Check the Expiry Date
- Read labels: Always check the expiration date on the packaging before using the bleach. If it’s past the expiration date, it’s safer to discard the product.
2. Store Properly
- Cool and Dark Place: Store your hair bleach in a cool, dark place, away from direct sunlight and extreme temperatures. This helps preserve the stability of the chemicals in the product.
3. Follow Manufacturer’s Instructions
- Read Instructions: Carefully read and follow the manufacturer’s instructions for mixing and applying the bleach. Using the product as directed ensures both safety and optimal results.
4. Perform Patch Tests
- Skin Sensitivity: Before applying bleach to your entire head, perform a patch test to check for any adverse reactions or allergies. This is especially important if you are using a new bleach or a product you haven’t used in a while.
Common Myths About Hair Bleach Expiration
1. Myth: Expired Bleach Is Harmless
- Reality: Using expired bleach can be risky. The chemicals in bleach lose their potency over time, and applying an expired product may result in uneven colour, hair damage, or skin irritation.
2. Myth: All Bleach Has the Same Shelf Life
- Reality: Different brands and formulations of bleach may have varying shelf lives. Always refer to the specific product’s label for accurate information on shelf life and expiration.
