  • Start by washing your hair at least 24 hours before the bleaching process.

How Long To Leave Bleach In Hair 30 Vol – Factors That Affect Timing

Bleaching your hair is a big decision, and one important aspect to consider is how long to leave the bleach in. Whether you’re going for a full-on platinum blonde or just a few highlights, the timing of the bleaching process is critical in achieving your desired result.

In this post, we will explore the key factors that affect the timing of leaving bleach in hair with 30 vol.

The Natural Color And Texture Of Your Hair

The natural color and texture of your hair can have a significant impact on the amount of time bleach needs to process. Here are some key points to keep in mind:

  • The darker your hair, the longer it will take for the bleach to take effect.
  • Coarser hair may need a longer processing time than fine hair.
  • Hair that has already been colored or treated may need more time for the bleach to lift previous color or chemical treatments.

The Desired Level Of Lightening And Tone

The level of lightening and tone you desire will also determine how long to leave the bleach in your hair. Consider the following:

  • If you want a subtle change, you may need less time for the bleach to process.
  • For significant lightening, you will need to keep the bleach in for more time.
  • If you want to achieve a specific tone, such as ash or platinum, you may need to process the bleach for longer to reach the intended result.

The Strength And Developer Ratio Of The Bleach Mixture

The strength and developer ratio of your bleach mixture will also impact the length of time you need to leave the bleach in your hair. Here are some things to keep in mind:

  • A 30 vol bleach mixture will lift color and lighten hair more quickly than a 20 vol mixture, but it may also be more damaging to your hair.
  • The developer ratio, or the amount of developer used in the bleach mixture, can also affect the process time. A stronger developer will require less processing time, while a weaker one may require a longer process.

Ultimately, the length of time to leave bleach in hair with 30 vol will vary based on your unique circumstances. It’s essential to consult with a professional stylist to determine the best approach for your hair. With careful consideration and execution, you can achieve the perfect shade and tone for your hair without compromising its health.
