Introduction:

If you are in an idea about changing your hair color? There are two extents you have to look after. One is how your hair color adds to your personality and another is to think about the side effects it may cause. Though some chemically induced side effects are evident, safe coloring products with natural ingredients are also available.

Why Do People Prefer Hair Coloring?

There are various reasons why people prefer hair coloring.

  • The first and foremost reason is to cover up the gray strands.

  • Way of life to build up a personality.

  • Make hair vibrant and interesting by improving its shine and dimension.

  • Revitalize the style.

  • Build strength of weakened hair.

What Are the Ingredients in a Hair Dye?

According to the National Cancer Institute, there are 5000 chemicals in hair dye. These chemicals can cause lasting changes in the hair shaft.

Some of these chemicals are,

  • Para-phenylenediamine.

  • Ammonia.

  • Hydrogen peroxide.

  • Resorcinol.

  • Lead acetate.

  • Toluene.

  • Lead.

  • Mercury.

What Are the Types of Hair Coloring?

  • Permanent Hair Coloring: This type of hair coloring allows penetration of dye deep into the hair shaft. This is due to the ammonia content present in it. It has to be done only once a year.

  • Semi-Permanent Hair Coloring: This allows partial penetration into the hair shaft but completely coats the hair with color.

  • Temporary Hair Coloring: It contains water, organic solvents, and other agents.It is available as gels, sprays, and rinses.This type does not penetrate the hair and thus touch-up is done once a week.

  • Bleaching: It is used to lighten the natural hair color.

  • Ammonia-Free Dyes: These hair colors do not contain ammonia but contain other ingredients like hydrogen peroxide, resorcinol, etc. These aid in softening the hair. These are less damaging than the other types.

How Does Hair Dye Affect Your Hair?

Dyeing would lead to some adverse effects such as,

  • Excessive dryness.

  • Breakage of hair strands.

  • Excessive split ends.

  • Change in hair texture.

  • Loss of luster of hair.

  • Hair loss.

  • Damages the strength of the follicles.

  • Itchy scalp.

  • Excessive redness.

  • Irritation of the scalp.

  • In rare cases, the dye gets washed away with water.

What Are the Side Effects That Each Ingredient Cause?

  • Hydrogen Peroxide: Certain cheap hair colors contain ingredients that are toxic to human health. They usually contain aromatic amines and phenols, which contain hydrogen peroxide acting as a bleaching agent that breaks down the melanin pigment of the hair and colors the hair. Hydrogen peroxide is also the key ingredient in permanent hair dyes. Besides the bleaching effect, the peroxide component damages the hair and gives a sulfurous smell, and causes the eyes to sting.

  • Para-Phenylenediamine: It is the primary coloring agent and it is found to be carcinogenic. However, the exact mechanism is not completely known, and more scientific research has to be done to establish the link between hair dye and cancer. Besides its carcinogenic effect, para-phenylenediamine is linked to skin sensitization. It can cause itching, irritation, and redness of the skin. Certain studies have shown that it can lead to birth defects, liver damage, and blood toxicity on extreme exposure.

  • Ammonia: It breaks down the hair’s protein layer and allows the dye to gain access to the hair shaft. Ammonia is found to cause irritation of the skin, endocrine damage, and respiratory issues such as coughing, wheezing, breathing difficulty, and tightening of the chest. Asthmatic individuals can present with these symptoms if there is continuous inhalation of these chemicals.

  • Lead and Mercury: These components can lead to skin rashes as the chemicals seep into the skin. They can also cause dermatitis of the eye, ears, scalp, and face. The eyes get inflamed when these chemicals get exposed while coloring the eyebrows and eyelashes. So it is better to avoid them. And lead acetate is found to be neurotoxic.

  • Resorcinol: It can cause hormonal disturbance and toxicity to the organ system.

  • Toluene: It is an intermediate product in a hair dye that can lead to headache, dizziness, skin rashes, liver damage, kidney damage, and birth defects on massive exposure.

It is important to understand that these chemicals are not as toxic as they are found to be if there is no excessive exposure. So to get rid of the side effects, it is good to reduce the frequency of hair coloring and to check for the concentration of the ingredients.

What Are the Alternatives to Chemical Hair Coloring?

The safest way to get rid of the harmful effects of hair dyeing is to choose the natural path. There are naturally available substances that can color your hair.

They are,

  • Henna leaves.

  • Tea leaves.

  • Coffee beans.

  • Carrot and beetroot juices.

  • Herbs like rosemary, sage, and nettle.

  • Lemon extracts.

What Are the Precautions to Be Followed?

  • Avoid permanent hair coloring.

  • Opt for semi-permanent, temporary, and natural hair coloring.

  • Do it professionally.

  • Never dye your eyebrows and eyelashes.

  • Take your own color to the salon.

  • Do not color your hair frequently.

  • If asthmatic, try avoiding hair coloring as certain chemicals in the hair dye can aggravate respiratory problems.

  • Hair coloring should be avoided by individuals with psoriasis and eczema.

  • If you are doing it yourself.

The guidelines to be followed are:
