We’ve broken down everything you need to know about hydrogen peroxide, including what it does to hair, so you are able to make a well-informed choice whenever you are considering switching your hair color.

Let’s get started. 

What is Hydrogen Peroxide? 

Hydrogen peroxide hair bleach is an oxidizing agent with antibacterial effects. Because of this, it is applied to clean wounds in a medical context. This substance is also a common bleaching ingredient in dyes and lightening procedures. 

It is a bleaching substance that aids in erasing the natural colour in your hair so that a new color may readily take its place. It lightens the hue by releasing the oxygen and pigment that give your hair strands their natural color.

When used in conjunction with hair dye, hydrogen peroxide to lighten hair enables the pigment to penetrate your hair more deeply and take the place of your natural pigments for a long-lasting color change.

It is very different from semi-permanent dyes, which cover your hair’s outer layers rather than the cortex as hydrogen peroxide does.

Let’s get started. 

4 ways on how hydrogen peroxide for bleaching damages your hair? 

Hair Loss 

Hair loss is one potential side effect of hydrogen peroxide damage. Keep in mind that hydrogen peroxide is an oxidizing chemical that can cause your hair to become brittle and fragile, increasing the likelihood that it will fall out. Your hair ages more quickly as a result, which can cause balding or hair loss before its time.

Additionally, because hydrogen peroxide for lightening hair already damages proteins and results in split ends and breaking, you could experience significant hair loss as a result of that.

Scalp Burns 

If hydrogen peroxide is applied incorrectly, it can potentially cause burns on the scalp. The NCBI claims that caustic substances like hydrogen peroxide can result in chemical burns. According to the study, the use of chemicals can influence whether a caustic reaction causes irritating dermatitis, superficial chemical burns, or severe burns based on how the ingredients are used and their quantities as well. 

So, before applying anything it is better to consult with a personal hair stylist or health care professional to prevent such disasters. 

Severe Hair Damage

Hair Damage

Hydrogen peroxide for lightening hair is a strong bleaching agent that works by breaking down the natural pigments in your hair. This process, while lightening your hair color, can also weaken the protein structure of your hair strands. Hydrogen peroxide makes your hair more vulnerable to damage, including dryness, brittleness, and hair loss as well. It makes the outer layer of your hair – rough, causing the hair to lose its smooth and shiny appearance.

Color Variation

Achieving consistent and even color when using hydrogen peroxide hair dye can be challenging as it leads to uneven color variation on your hair. The bleaching process will impact the different parts of your hair in an uneven form, which leads to color patches of lighter and darker hair. This uneven color distribution can result in an unnatural or blotchy appearance on your hair.
