Hair colour

What is Hair Colour ?

Hair color refers to the pigments that give color to human hair. It can be natural or artificial and can be used to enhance or change the color of hair. Artificial hair color is achieved through the use of hair dyes, which can be permanent, semi-permanent, or temporary. There is a wide range of hair colors available, from natural shades such as black, brown, and blond, to more creative and bold colors like pink, blue, or purple. The choice of hair color depends on personal preference and skin tone.

 

How Hair Colours works ?

Hair color works by depositing pigments onto the hair shaft to change or enhance its natural color. The color molecules in hair dyes are small enough to penetrate the cuticle layer of the hair and bind to the cortex, which is the inner layer of the hair shaft. The process of hair coloring typically involves opening the cuticle layer with an alkaline solution, applying the color, and then closing the cuticle with an acidic solution to lock in the color.

The type of hair color and the method used will determine the level of permanency. Temporary hair color is usually washed out after a few washes, while semi-permanent color will gradually fade over time. Permanent hair color is the most long-lasting and requires a chemical process that rearranges the hair's molecular structure.

It's important to keep in mind that hair color can be damaging to the hair, especially if it is done frequently or with harsh chemicals. It's a good idea to use a good quality hair dye and to follow the manufacturer's instructions to minimize damage to the hair. It's also advisable to have a patch test before coloring your hair to ensure that you are not allergic to the ingredients in the hair dye.

is Hair colours safe to use ?

Hair color can be safe to use when done correctly and with proper precautions, however, overuse or incorrect use of hair color can be damaging to the hair and scalp. Here are some of the potential risks associated with hair coloring:

1. Allergic reactions: Some people may be allergic to the ingredients in hair dye, which can cause skin irritation, itching, redness, or even more serious symptoms such as swelling or difficulty breathing.

2. Chemical damage: Hair dyes contain chemicals that can penetrate the hair shaft and cause damage to the hair and scalp, especially if the hair is over-processed or left on for too long.

3. Scalp irritation: Some people may experience scalp irritation, redness, or itching after using hair dye, especially if they have a sensitive scalp.

4. Fading or discoloration: Over time, hair color can fade or discolor, especially if exposed to sunlight, heat, or harsh chemicals.

To minimize the risks associated with hair coloring, it's important to use a good quality hair dye and to follow the manufacturer's instructions carefully. It's also advisable to have a patch test before coloring your hair to ensure that you are not allergic to the ingredients in the hair dye. If you experience any symptoms of an allergic reaction or scalp irritation after coloring your hair, stop using the product and seek medical advice.

which chemical in hair colours are not safe

There are several chemicals in hair dyes that can be harmful, especially if not used properly. Here are some of the most common harmful chemicals found in hair dyes:

1. P-phenylenediamine (PPD): PPD is a common ingredient in permanent hair dyes and is known to cause skin irritation, itching, and allergic reactions in some individuals.

2. Ammonia: Ammonia is used in many hair dyes to open up the hair cuticle and allow the color molecules to penetrate the hair shaft. However, it can be harsh on the scalp and cause dryness, itching, and hair damage.

3. Hydrogen peroxide: Hydrogen peroxide is used in many hair dyes to lighten hair and remove natural pigments. It can cause hair damage, dryness, and breakage if not used properly.

4. Resorcinol: Resorcinol is a chemical found in some hair dyes and can cause skin irritation, itching, and redness, especially in people with sensitive skin.

5. Lead acetate: Lead acetate is a toxic chemical that has been found in some hair dyes and can cause serious health problems, including lead poisoning, if ingested.

It's important to be aware of these harmful chemicals and to choose hair dyes that are free of these ingredients, or to limit your use of hair dyes containing these chemicals. You can also opt for natural hair dyes made with herbal ingredients that are gentler on the hair and scalp. It's also a good idea to have a patch test before coloring your hair to ensure that you are not allergic to the ingredients in the hair dye.
