Hair Colouring, Types and the Process of Hair Colouring?

Hair colouring is a popular practice used to change hair colour. It can be done professionally or at home, and its main reasons include covering gray or white hair, changing to a more fashionable or desirable colour, or restoring the original hair colour after discolouration from hairdressing processes or sun bleaching.

Types of Hair Colouring

There are four types of hair colouring: permanent, demi-permanent, semi-permanent, and temporary. Each type has a different chemical composition, and the process and duration of the colour vary.

Permanent Hair Colouring

Permanent hair colouring involves ammonia, which opens the cuticle layer, and a developer or oxidizing agent to penetrate the cortex and permanently change the hair colour. The higher the developer volume, the higher the “lift” of a person’s natural hair pigment. Permanent hair colouring takes approximately 30 to 45 minutes to achieve maximum colour change.

Demi-Permanent Hair Colouring

Demi-permanent hair colouring uses an alkaline agent instead of ammonia and a lower concentration of hydrogen peroxide in the developer. It provides almost no lightening of hair’s colour during dyeing, and as a result, it cannot colour hair to a lighter shade than it was before dyeing. Demi-permanent hair colouring is more effective at covering gray hair than semi-permanent hair colouring and is less damaging to hair than permanent hair colouring. The colour lasts for 20 to 28 shampoos.

Semi-Permanent Hair Colouring

Semi-permanent hair colouring involves no developer or ammonia and is less damaging to hair than demi-permanent and permanent hair colouring. The final colour depends on the hair’s original colour and porosity and is subtle and natural-looking. It is not effective in covering gray hair, and the colour lasts for 4 to 8 shampoos.

Temporary Hair Colouring

Temporary hair colouring is available in various forms such as rinses, shampoos, gels, sprays, and foams. It is typically brighter and more vibrant than semi-permanent and permanent hair colouring and lasts for only a single shampoo. The pigments remain adsorbed to the surface of the hair shaft and can persist on excessively dry or damaged hair.

Alternative Dyes and Hair Colour

The chemical formulae of alternative colour dyes typically contain only tint and have no developer. This means that they will only create the bright colour of the packet if they are applied to light blond hair. Darker hair (medium brown to black) would need to be bleached in order for these pigment applications to take to the hair desirably. Some types of fair hair may also take vivid colours more fully after bleaching. Gold, yellow and orange undertones in hair that has not been lightened enough can muddy the final hair colour, especially with pink, blue and green dyes. Although some alternative colours are semi-permanent, such as blue and purple, it could take several months to fully wash the colour from bleached or pre-lightened hair.

Hair Colouring Application Process

Off-Scalp Hair Colouring Techniques

Hair colouring has come a long way from the traditional method of applying a single overall colour. Nowadays, people prefer to use various colours to create streaks or gradations. However, not all of these colours work on top of a single base colour. Off-scalp techniques are used to achieve the desired effect. Some of the popular off-scalp hair colouring techniques are:

Highlighting: In this technique, sections of hair are treated with lighteners to create lighter streaks.

Lowlighting: This technique involves treating sections of hair with darker colours to create darker streaks.

Splashlighting: In this technique, a horizontal band of bleached hair is created from ear to ear to achieve a dramatic effect.

Balayage, and Airtouch: These are newer hair colouring techniques that involve darkening the hair on the crown and gradually lightening it towards the ends.

These techniques can be applied using various methods, such as:

Foiling: Foiling is a method that involves using pieces of foil or plastic film to separate the hair to be coloured. This method is especially useful when applying more than one colour to the hair. Foiling ensures that only the desired strands of hair are coloured while the rest are spared.

Cap: This method involves placing a plastic cap tightly on the head and pulling strands of hair through with a hook. It is mostly used to apply highlights to short hair.

Balayage: This technique involves painting the hair colour directly onto sections of the hair without using foils to keep the colour contained. Balayage is growing in popularity due to its natural appearance. The difference between balayage and ombré is that balayage requires more precise hand-painting of hair sections and typically costs more.

Baby Lights: This technique involves creating very thin highlights using a fine colour technique. The results are subtle and natural-looking.

Dipping or Tip Dyeing: In this technique, the tips of the hair are dipped directly into dye.

All hair colouring techniques can be used with any type of colour. However, for lightening, the hair sometimes needs to be bleached before colouring.

On-Scalp Hair Colouring Techniques

On-scalp hair colouring techniques are used for a more solid level of coverage. Some of the popular on-scalp hair colouring techniques are:

Root Touch-Up: This technique involves applying colour only to the most recent section of re-growth, usually the first inch of hair nearest the scalp. Root touch-ups are repeated every 4–6 weeks as the natural colour grows in and becomes apparent. People who colour their hair to disguise gray often use this technique.

All-Over Colour: In this technique, the person wants all of their hair to be a different solid colour.

Block Colouring: This technique involves applying two or more colours to the hair, resulting in dimension and contrast.

All hair colouring techniques can be used with any type of colour. However, for lightening, the hair sometimes needs to be bleached before colouring.
