Hydrogen Peroxide Effects on Hair

Lightening Hair

Hydrogen peroxide is an ingredient in hair dyes. It is usually used to lighten hair.

The way it works is simple: Removing the natural pigment of your hair and letting a new color replace it. Hydrogen peroxide penetrates and works the hair cortex. In general, it will cast a shade or two lighter.

Negative Consequences 

Nevertheless, excess or improper use of hydrogen peroxide can cause problems, such as skin irritation, hair cuticle damage, and hair loss. 

Skin Irritation 

Even though hydrogen peroxide can be used as a disinfectant, too much of it can also irritate your skin. With dye jobs, hydrogen-peroxide-induced irritations can occur around your hairline and on your scalp. 

It can lead to dermatitis, which is basically, inflammation of the skin. You can get nasty allergic reactions and rashes, as a result.

Serious reactions can even result in chemical burns and deep burns! So, it is extremely necessary to use hydrogen peroxide within its recommended quantities.

To minimize the chances of skin irritation, keep these two tips in mind:

  • Protect your hairline with petroleum jelly. 
  • Leave hydrogen peroxide on your hair for as little time as possible. 

Hair Cuticle Damage 

Using too much hydrogen peroxide or using it incorrectly can damage the outer layer of the hair, known as the cuticle.

This layer is supposed to protect your hair and strengthen it. Hence, if it is damaged, your hair becomes prone to breakage, split ends, and frizz. 

To reduce the damage that hydrogen peroxide inflicts on your hair cuticles, you should use a hair conditioner and deep conditioner treatments.

Hair Loss

Hydrogen peroxide is cytotoxic. It can inflict oxidative stress on hair. This stress is what causes your hair to age and shed.

As a result, you can suffer from severe hair loss. Besides, breakage that happens because of cuticle damage contributes to hair loss. 

Hence, it is important to follow the directions on the packaging closely and avoid using pure hydrogen peroxide while lightening or coloring your hair.

Why Does Gray Hair Turn Yellow

There are several reasons why gray hair turns yellow, as follows:

  • Your hair has accumulated minerals and chemicals in water, which deposit and attach to the hair shaft, resulting in a yellow cast. 
  • Your hair has aged through a process called achromotrichia and therefore, has lost pigments. 
  • Your hair’s remaining pigments can be bleached by the sun; the more-blue natural molecules are removed, leaving only the more-yellow ones. These, ultimately, become more visible. 
  • Your hair has picked up pigments from your low-air-quality environment, like (from) smoke, which can build up and lead to discoloration. 
  • Your hair has been discolored by hair products that have sulfates or added dyes. 
  • Your hair has buildups because of hair products that have silicones. 
  • Your hair has been affected by medications, such as chemotherapy drugs, malaria drugs, thyroid and hormone medications. 

How To Keep Your Gray Hair White 

How to keep your gray hair from turning yellow

Change your shower head 

Switching for a shower head with a filter can prevent your hair from yellowing as the filter will keep minerals, sediments, additives, and chemicals out. 

Note: You should change the filter every six months to make sure you continue to get soft, clean water. 

Wear a hat when you go outside 

Hats are fantastic accessories to prevent sun damage and environmental impact, like pollutants. You can safeguard your hair and prevent it from turning yellow easily by throwing on a hat. 

Use a clarifying shampoo once a week 

Clarifying shampoos can help deyellow your gray hair, as they are specially made to remove buildups and stubborn residue on your hair.

Your hair will be left extra clean. So, there is no chance for accumulations to turn your hair yellow. 

Avoid using hair products with sulfates and silicones 

As mentioned briefly in the beginning, sulfates-containing products can discolor your hair, while silicones-containing products can bind your hair strands and so, lead to build-ups, which results in yellowing.
