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.

4. Perform Patch Tests
