8 Chemicals Found in Most Hair Dyes to Avoid

Posted by KatakamiYuki on

Skin absorption rates vary greatly among different parts of the body; for example, the chemical absorption rate on your forehead and scalp is about four times greater than the absorption rate on your forearms. Do you color your hair? Take a look at the ingredients list on your product.

1. P-phenylenediamine PPD

PPD is short for para-phenylenediamine. It is used as a dye for dark color shades and is made from coal tar, a petroleum-derived chemical that includes benzene, naphthalene, phenols, aniline, and other chemicals. It is also used as a wood preservative, and contact with skin is best to be avoided.
PPD can cause reactions ranging from mild skin irritation to more severe allergic contact dermatitis. Sensitive individuals may experience dermatitis—skin inflammation and irritation commonly referred to as eczema. In more serious cases, there may be marked reddening and swelling on the scalp and the face. An allergy to PPD can result in widespread contact dermatitis, as well as hives and, in rare severe cases, anaphylaxis.

2. Hydrogen peroxide

Hydrogen peroxide is oxygen water. It is the activator that you add to the colour cream when you dye your hair. Peroxide is used as the developer or oxidizing agent. It removes pre-existing color.

Hydrogen Peroxide is said to change the hair structure and make it brittle stripping it of its natural luster.

3. Ammonia

Ammonia is used to open up the hair’s cuticle (the outer layer of the hair) so the dyes can come into the shaft (the inside of the hair).
Ammonia not only can cause skin irritation, but if it gets into your bloodstream you could get sick. Ammonia can also impact the earth by endangering animals in the ocean and crops on the land.

4. Ethanolamine

Ethanolamine is used in our demi-permanent hair colorants instead of Ammonia.
Ethanolamine is similar to ammonia, but can actually damage your hair more. You may also notice more hair loss and there can even be a risk of birth defects.

5. DMDM hydantoin

DMDM hydantoin is a formaldehyde releaser or donor, meaning it slowly releases the chemical formaldehyde as it breaks down in the product over time to prevent mold and bacteria from growing. It works by slowing or stopping the growth of potentially harmful microbes such as fungi, yeast and bacteria.
DMDM hydantoin has come under fire in recent years, mainly because it releases small amounts of formaldehyde. It may cause tissue irritation and affect the immune system.

 

6. SLS

Before you use your go-to hair color, check for these ingredients: sodium laureth sulfate, sodium lauryl sulfate, or sodium chloride. These ingredients act like a deep-cleaning detergent that can actually strip your hair of its new color.
It not only strips your hair of dirt but also essential, natural oils which can leave your hair weak and prone to breakage. Continuous exposure to sodium laureth sulfate can even cause skin irritations.

 

7. Resorcinol

Resorcinol (or benzene-1,3-diol), is a chemical that is commonly used in hair colour, hair dyes, skin peels, and during acne treatments. It reacts with the peroxide-containing developer to give the required colour or shade.
Resorcinol is a toxic dye that can cause scalp irritation, and is an allergen affecting the endocrine system.

 

8. Methylchloroisothiazolinone

Methylchloroisothiazolinone is a preservative in many skin care products, household cleaners, and hair dye products that stops fungi, yeast, and bacteria from growing.
Methylisothiazolinone engages your immune system and irritates your skin. Once this happens you may become permanently allergic to methylchloroisothiazolinone the next time you are exposed to it.

 

There is plenty of plant- and henna-based hair colors out there that offer a safer and less damaging alternative to traditional chemical dyes. Organic hair dye is safer than Natural hair dyes. Organic hair dye is hair color made from organic botanical components (usually meaning free from pesticides) and without being subject to certain damaging chemical processes.
Radico's hair colorants contain only natural, certified organic ingredients.
