Summary

In this video, the host explains the various types of peroxide used in hair coloring, particularly focusing on hydrogen peroxide as an oxidizer. Different peroxide strengths, ranging from 10V to 40V, are discussed in terms of their functions, strengths, and best uses for different hair types. The host emphasizes the importance of choosing the right peroxide for the desired color result while also warning about the risks of overusing stronger peroxides, especially 40V, which can damage hair. Tips on how to safely bleach and color hair are also shared.

Takeaways

• 😀 Peroxide, also known as hydrogen peroxide, is used as an oxidizer for lightening hair color.
• 😀 Peroxide works by opening the hair cuticle to allow the color pigment from hair dye to enter the hair shaft.
• 😀 There are four main types of peroxide, differentiated by their hydrogen peroxide content, each with its own purpose.
• 😀 Peroxide strengths are typically measured in volumes (vol), such as 10, 20, 30, and 40, which correlate with the percentage of hydrogen peroxide.
• 😀 10vol (3%) is used for refreshing existing hair color and is gentle, with minimal color change.
• 😀 20vol (6%) can lighten or darken hair by 1-2 levels, suitable for gradual color changes and longer processing times.
• 😀 30vol (9%) is used for lightening hair by 2-3 levels, and works faster but for a shorter duration, around 90 minutes.
• 😀 40vol (12%) is the strongest peroxide, capable of lightening hair by 3-4 levels but comes with a higher risk of damage.
• 😀 40vol should be used with caution as it can damage the hair cuticle and cause dryness, breakage, and split ends.
• 😀 If a higher level of lightening is needed but 40vol is too harsh, a safer option is to use a bleaching product combined with a 20vol or 30vol peroxide.

Q & A

What is peroxide, and what role does it play in hair dyeing?

Peroxide, specifically hydrogen peroxide, is a chemical compound used as an oxidizer to lighten hair color. It works by opening the hair cuticle to allow the dye pigment to penetrate the hair shaft, resulting in a color change.

What are the different types of peroxide based on their hydrogen peroxide content?

The four common types of peroxide are differentiated by their hydrogen peroxide content: 10 volts (3%), 20 volts (6%), 30 volts (9%), and 40 volts (12%). Each type is used depending on the desired lightening level and hair type.

How does the 10-volt peroxide work in hair coloring?

10-volt peroxide (3%) works slowly and is primarily used to refresh the color on already colored hair. It doesn’t lighten hair but can enhance the color’s reflection, making it suitable for maintaining the vibrancy of previously dyed hair.

What is the primary function of 20-volt peroxide (6%)?

20-volt peroxide (6%) is used to lighten hair by 1 to 2 levels. It gradually opens the hair cuticle and is typically used for safe and controlled color changes, often requiring longer processing times to achieve desired results.

How does 30-volt peroxide (9%) work compared to 20-volt peroxide?

30-volt peroxide (9%) is faster in lightening hair, offering a 2 to 3-level lightening effect. The reaction is quicker, usually within 90 minutes, but after this time, it stops working. It is used for more dramatic lightening effects than 20-volt peroxide.

What makes 40-volt peroxide (12%) the strongest and most risky option?

40-volt peroxide (12%) can lighten hair by up to 4 levels very quickly. While it delivers rapid results, it is also the most aggressive, opening the hair cuticle widely and risking significant damage such as dryness, breakage, and split ends. It should be used cautiously and only on very strong hair types.

Why is 40-volt peroxide not recommended for most hair types?

40-volt peroxide is too harsh for most hair types because it can cause severe damage, especially to fine, dry, or previously damaged hair. The excessive opening of the hair cuticle leads to the loss of essential proteins and moisture, making hair brittle and prone to breakage.

When should you consider using a bleach mixture instead of high-strength peroxide?

If you need to lighten hair beyond the capabilities of 20-volt or 30-volt peroxide, it's safer to use bleach with a more suitable peroxide strength (20-volt or 30-volt) depending on hair type. This helps achieve the desired level of lightness without excessive damage.

What are the risks of using 40-volt peroxide in bleaching or color treatments?

The risks of using 40-volt peroxide include rapid damage to the hair due to its strong oxidizing properties. This can lead to the hair becoming dry, brittle, and frizzy, as it strips away vital proteins and moisture from the hair shaft.

What hair types are suitable for using 40-volt peroxide?

40-volt peroxide is generally suitable only for very thick, coarse, or oily hair types, such as naturally black, glossy hair. These hair types are more resilient and can tolerate the strength of 40-volt peroxide without immediate severe damage.
