Hair dye ingredients Side Effects, 영-한

 

most harmful ingredient in hair dye;

Ammonia is advertised as the most damage causing ingredient to hair.

The primary function of ammonia is to raise the pH of the hair sufficiently so as to open the cuticles[큐티클, (손톱, 발톱 뿌리 부분을 덮고 있는) 단단한 피부층, 각피] and allow the colour to enter the cortex[(특히 대뇌) 피질],

the thickest hair layer containing the most pigment[(동물,식물 등에 자연 상태로 존재하는) 색소] which gives hair its colour,

 

Negative effects of hair dye;

Altering the hair's protein structure through permanent and demipermanent-[^밑에 참조] dyeing can cause side effects that include:

loss of hair strength. less ability for your hair to handle heat styling. reduced hair thickness.

[[ ^^ Demi-permanent : The in-between sweet spot. It can create more color change and last longer than semi-permanent. Typically, this type of dye can last anywhere from 24 to 28 washes before completely washing out. Demi-permanent dye lasts longer because it has a small amount of peroxide incorporated to open the outer layer of the hair,]]

Can hair dye affect the brain?

In recent years, a great number of studies investigated the relationship between hair dyes use and risk of glioma [12-18]. In a previous meta-analysis, Takkouche and colleagues found that hair dyes use is associated with increased risk of brain tumor.

 

Does hair dye affect your kidneys?

Resorcinol found in hair dyes is a phenol derivative, which may also contribute to renal toxicity.

In addition, a few hair dyes also contain lead acetate and Bismuth sulfate, which can cause chronic kidney disease or acute interstitial nephritis respectively.

These chemicals can remove the protective lipids[지방질들] / oils from your scalp, leaving it exposed and vulnerable to damage from the environment, styling products and other irritants. You may see these symptoms: Stinging.

 

Can hair dye make you sick your stomach?

Does all hair dye have PPD?

PPD; ParaPhenyleneDiamine, 파라페닐렌다이아민,

Even many semipermanent dyes, lasting through 8-12 shampooings, contain PPD.

The only dyes that do Not reliably contain PPD are the temporary hair dyes that only last through one shampooing, which most women do not find satisfactorily as the hair needs to be redyed each time it is cleaned,

Types Of Hair Dyes;;

 

- Permanent Hair Dyes ; They penetrate through the hair shaft, reaching the cortex. They need to be touched up at least once every twelve weeks. Most permanent dyes use ammonia to penetrate the hair shaft and increase the pH level.

 

- Semi-Permanent Hair Dyes ; They coat the hair shaft cuticle while partially penetrating the cortex.

- Temporary Hair Dyes: They don’t penetrate the hair cortex and need to be touched up every few weeks.

- Bleach: It is used to lighten hair and color dark hair like black and brown to lighter hair colors like blonde or red.

- Ammonia-Free Hair Dyes ; They are also called demi-permanent hair dyes. They don’t contain ammonia but include hydrogen peroxide, para-dyes, and resorcinol. These are softer on the hair.

Side Effects of Hair Dyeing;;

 

Note: All of the information given below is in reference to permanent hair dye unless otherwise specified.

 

Hair coloring is just basic chemistry. It is all about the reactions that take place in between the pigments in your hair, the pigments in dye, peroxide, and ammonia.

with all the experience we have had with chemicals, the one thing we have come to accept is that they are usually not good. Here’s why:

 

1. Over Processing,

Permanent hair colors often contain ammonia (or chemicals similar to it) and peroxide (1). The ammonia breaks through your hair shaft, and the peroxide neutralizes (or bleaches out) the natural pigment in your hair, stripping away color. This process of relaxing the hair cuticles to reach the cortex of your hair and bleach out its natural pigment is, essentially, hair damage

 

Over treating your hair with these chemicals will cause it to lose luster, break easily, and in some extreme cases, wash away with water. While processed hair can be revived to a certain extent with hair care treatments, the only way to get rid of the damage from over-processing is to chop your hair off.

 

2. Allergic Reactions;

Hair dyes causing allergic reactions is not uncommon, especially because permanent hair dyes contain paraphenylenediamine, which is a common allergen (2).

 

People who have contact dermatitis are particularly prone to reactions because of the PPD and other chemicals present in dyes. People with skin conditions, like eczema and psoriasis, should also refrain from using hair dyes to color their hair. In milder cases, permanent dyes can cause itching, skin irritation, redness, or swelling on your scalp or other sensitive areas like your face and neck.

Another thing to keep in mind when using these dyes is that not having had an allergic reaction in the past does not mean you won’t have one in the future. The more you color your hair, the more likely you become to having an adverse reaction.

 

3. Effects on Fertility;

Research is inconsistent in this regard. Though a few studies state that there is minimal systemic absorption of hair products, hair dyes may not actually affect fertility or pregnancy. However, since they show a possible risk of being exposed to hair dyes for prolonged periods, it is better to avoid hair dyes if you are looking to conceive or are pregnant.

 

4. Upkeep;

While this is not technically a side effect, it can be cause for some. A lot of people don’t realize just how much goes into the upkeep of colored hair. It is a long-term commitment that will have you rushing back to the salon every month or so, which can be hard on your hair.

 

You will need to buy products that are specially formulated for colored hair. A few styles need regular touch-ups, and your hair, in general, needs so much extra care.

 

Post processed hair is really vulnerable to damage and demands a lot of time, patience, and care. Failing to give your hair what it needs will result in locks that lack shine, luster, and health.

 

5. Conjunctivitis, 결막염 ;

Conjunctivitis is one of the side effects of hair dyeing Conjunctivitis is one of the side effects of hair dyeing Conjunctivitis is one of the side effects of hair dyeing,

Failing to exercise extreme caution when dyeing your hair can result in the chemicals making contact with the sensitive parts of your face. In some cases, when chemicals from hair dyes make contact with your eyes, it can lead to conjunctivitis or pink eye.

In other cases, it causes inflammation and severe discomfort.

 

6. Asthma, 천식;

Hair dyeing may cause asthma attacksHair dyeing may cause asthma attacks Hair dyeing may cause asthma attacks

Asthma is one of the symptoms of a severe allergic reaction to hair dyes (6). Continued inhalation of the chemicals in hair dyes can lead to coughing, wheezing, lung inflammation, throat discomfort, and asthma attacks.

 

7. Cancer, 암;

When permanent hair dyes were first introduced, they had compounds that were carcinogenic (cancer-causing.) While the formulas were altered to replace these chemicals, the debate as to whether hair dyes can cause cancer has not been put to rest (7). On the contrary, more scientific research and studies are needed to establish a definite link between the use of permanent hair dye and cancer.

Here are some precautions you could take to minimize the risk of possible side effects.

 

;;Precautions to take While Dyeing Your Hair;;

- Try to avoid using permanent hair color as much as possible. Instead, you could opt for semi- and demi-permanent hair colors. While these are temporary, they do not contain as many harmful chemicals as permanent hair colors do.

- Always conduct a patch and strand test before you dye your hair. The patch test will help you avoid a possible allergic reaction, while the strand test will help you determine if your hair is healthy enough to be processed.

- Get your hair done professionally. There is so much that can go wrong when you try to color your hair on your own. Go to a professional you trust to avoid a hair disaster.

- Always color your hair in a well-lit and well-ventilated area. Poor ventilation can cause eye and nasal irritation.

- Do your research and use products from trusted brands that do not use many harmful chemicals, even if this means that you will have to spend a little extra money.

 

The safest way to color your hair would be to give up permanent hair dyes and switch to natural hair dyeing alternatives.

1. Coffee / Tea,

Coffee or tea rinse as a natural alternative for hair dyes,

Freshly brewed coffee or tea can significantly darken light hair (8). All you need to do is pour the brew through your hair as a final rinse and let it air-dry. The color will wash out the next time you shampoo your hair, but you can just repeat the process as it has no side effects. In fact, some teas can actually improve the health and texture of your hair.

 

2. Food Color;

Food color and pigmented flavored drinks like Kool-aid can be used to attain a whole range of crazy colors. Mix the food color or Kool-aid with conditioner and apply it to your hair.

3. Beet and Carrot Juice;

a beet and carrot juice treatment is often used to add red undertones to blonde and light brunette hair. You need to mix 3 parts of beet juice with 1 part of carrot juice and saturate your hair with the mixture. Let it sit for about an hour and then rinse it out with shampoo.

 

4. Henna [헤나 (적갈색 염료)],

Henna as a natural alternative for hair dyes,

Henna is one of the most popular natural hair coloring treatments.

Make a paste out of henna powder and water and apply this to your hair.

Let it sit for a couple of hours and then proceed to shampoo and condition your hair.

 

5. Lemon and Honey;

Lemon and honey work well together to lighten your hair and give you natural highlights. Mix equal parts of the two ingredients and apply it to your hair. Sit out in the sun for an hour or apply heat using a blow dryer. Wash the mixture out with shampoo and then proceed to condition. You might have to repeat this process a couple of times to get visible results.

 

While it can be fun and exciting to play with hair dyes, it can damage the hair if done too often.

The side effects of hair dye range include the risks of overprocessing[과도한 진행시간] hair and the possibility of conjunctivitis. It may also trigger allergic reactions due to certain chemicals like PPD [ParaPhenyleneDiamine, 파라페닐렌다이아민], which may cause skin irritation and redness and, in severe cases, trigger an asthma attack. You should take proper precautions before and after getting your hair colored to avoid these problems. Limiting or avoiding the use of hair color can help avoid these complications. Safe, natural hair dye alternatives are another option you may consider.
