The science behind hair bleach and how it works

How Hair Bleach Works: The Science Behind the Magic

Hair bleach might seem like magic, but there’s some serious science at play. When you apply bleach, it breaks down the natural melanin pigment in your hair through an oxidation process. This reaction removes the color, leaving your hair lighter. Think of it as a chemical light switch that turns off your hair’s natural color!

Not all hair bleach works the same.

The Impact on Hair Structure: Handle With Care

Bleaching doesn’t just lighten your hair; it changes its structure. By making your hair more porous and fragile, bleach leaves your locks in need of extra TLC. Proper aftercare, like deep conditioning and protein treatments, is essential to keep your hair healthy and vibrant.

Types of Hair Bleach: Not All Bleach is Created Equal

Did you know there are different types of hair bleach? Whether it’s powder, cream, or oil-based, each type serves a unique purpose. Plus, bleach comes in different strengths, known as volume developers. The higher the volume, the more lift (and potential damage) you can achieve. Choosing the right type and strength is crucial for your hair type and desired outcome.

Timing Matters: Patience is Key

When it comes to bleaching, timing is everything. Depending on your hair texture, previous color treatments, and the level of lightness you want, processing times can vary. Over-processing can lead to severe damage, while under-processing might leave you with uneven results. It’s a delicate balance that requires careful monitoring. Personally I love using products like Olaplex to help repair bonds and help prevent breakage. Read this blog here on how I remove black box dye from the hair using hair bleach.

Heat Activation: Friend or Foe?

Applying heat can speed up the bleaching process, but it comes with risks. While heat can help achieve faster results, it also increases the potential for damage. That’s why professional supervision is recommended when using heat with bleach.

The Role of Developers: The Secret Sauce

Developers, the unsung heroes of hair bleaching, come in various volumes: 10, 20, 30, and 40. Higher volumes lift more color but can cause more damage. Choosing the right developer strength is key to achieving the perfect balance between lift and hair health.

Bleach Doesn’t Stop Working: The Ever-Lifting Process

Unlike hair dye, bleach keeps working until you wash it out. This means constant vigilance is required to avoid over-bleaching. Trust me; you don’t want to end up with fried hair!

Previous Treatments Matter: Your Hair’s History

Hair that has been previously colored or chemically treated may react differently to bleach. Knowing your hair’s history is essential to prevent unexpected results and potential damage.

Professional vs. DIY: The Great Debate

While DIY bleaching can be tempting, professional hairstylists are trained to assess your hair’s condition and choose the right products and techniques, reducing the risk of damage. Sometimes, leaving it to the pros is the best choice!
