Full Hair Colouring 

What Is Single-Process Hair Colour?

Single-process hair colouring involves applying one selected shade throughout the entire length of the hair to achieve an even, rich and cohesive colour. This classic salon service is ideal for refreshing dull hair, adding depth and intensity, or creating an even tone from roots to ends.

Depending on the condition of your hair and the desired result, all-over hair colour can gently deepen your base, change your natural shade or precisely cover regrowth. It is also one of the most reliable ways to achieve full grey coverage when the right formula and pigment density are selected.

Who Is All-Over Hair Colour Suitable For?

This service is an excellent choice if you want a consistent colour without uneven tones, wish to restore healthy shine or need to correct the results of previous colouring experiments.

Professional hair colouring can effectively cover regrowth or grey hair, correct uneven colour throughout the lengths, or help you return to your natural shade. The final result will always depend on your starting base, the porosity of your hair, any existing artificial pigment and whether preliminary preparation is required.

How to Choose a Shade for Single-Process Hair Colour

The ideal shade is not selected at random. Your colourist considers your natural base, overall colouring, skin undertone and eye colour. They will also assess how much previous colour has accumulated in the hair, whether grey coverage is required and whether the desired warm or cool tone can be achieved without pre-lightening.

The available palette makes virtually any colour direction possible. Natural and dark-blonde colour ranges include soft wheat, light-blonde and deep dark-blonde shades. If you prefer cooler tones, ash, pearl or graphite nuances may suit you. For softer warmth, consider golden, honey, caramel or copper shades. Delicate beige tones create a beautiful neutral result, while chestnut, coffee and chocolate shades add sophisticated depth to darker hair.

How Single-Process Hair Colouring Is Performed

Every appointment begins with a detailed consultation. The stylist examines your hair and assesses its density, level of damage and previous colour history.

The colourist then creates a personalised formula using the appropriate colour and developer before carefully applying it to the roots and lengths. While the pigment develops, the stylist monitors the process. The colour is then gently rinsed out using a specialist shampoo and conditioner designed to stabilise the result.

The service is completed with blow-drying, styling and clear professional recommendations on how to care for your new shade at home.

Single-Process Hair Colour vs Hair Toning

Single-process hair colour creates a long-lasting, deep colour change and can provide full grey coverage by working within the internal structure of the hair.

Hair toning is gentler. It adjusts the existing shade, adds a subtle colour nuance or refreshes the colour between full colouring appointments. After a quick hair assessment, your colourist will recommend the most suitable option for you.

How Long Does Single-Process Hair Colour Last?

The longevity of your colour depends on the chosen product, your hair’s initial porosity and its overall condition.

Everyday habits also have a significant effect on colour retention, including how often you wash your hair, the type of water you use, whether you apply heat protection before blow-drying or styling, and how much time your hair spends exposed to direct sunlight.

How to Care for Your Hair After Colouring

To keep your colour rich and prevent it from fading into unwanted tones, switch to a shampoo and conditioner formulated for coloured hair.

Always use a high-quality heat protectant before blow-drying or using hot styling tools, and avoid washing your hair with very hot water. If the colour begins to lose its intensity, you can introduce colour-depositing conditioners. To maintain the elasticity and condition of the ends, regularly apply a moisturising hair oil or serum.

What Determines the Single-Process Hair Colour Price?

Your stylist will confirm the final price at the salon before beginning the service.

The cost depends on the length and thickness of your hair, the amount of product required, the selected colour brand and the stylist’s level of expertise. The complexity of the starting base can also affect the price—for example, if uneven or patchy colour needs to be corrected before colouring.

If you are looking for a single-process hair colour price or an all-over hair colour price in Kyiv, the most accurate estimate can be provided after an in-person consultation and hair assessment.

Frequently Asked Questions

How Long Does Single-Process Hair Colour Take?

A typical appointment takes between 1.5 and 2.5 hours. The exact duration depends on the length and thickness of your hair and whether any additional salon treatment is required.

Can I Make My Hair Lighter Without Pre-Lightening?

Hair colour cannot lighten a previously coloured base. If your hair already contains artificial pigment, the shade can only be lifted through gentle colour removal or lightening.

Can the Colour Be Evened Out If the Roots and Lengths Are Different Shades?

Yes. The colourist will create a customised formula—for example, using different developer strengths for the root area and the previously lightened lengths.

Can I Have All-Over Hair Colour After Highlights or Lightening?

Yes. However, to ensure that a darker shade looks even and does not wash out into a muddy tone after a week, the colourist may first perform repigmentation. This restores the base pigments missing from previously lightened hair.

Can Hair Be Coloured After Henna or Indigo?

Chemical hair colour may produce an unexpected greenish or muddy result when applied over natural dyes such as henna or indigo. Your stylist will therefore carry out a strand test on a discreet section of hair first.

Should I Wash My Hair Before Colouring?

No, you do not need to wash your hair specifically before the appointment. The important thing is to avoid having a heavy layer of hairspray or dry shampoo on the hair. All necessary preparation will be completed at the salon basin.

Can Damaged or Highly Porous Hair Be Coloured?

Yes, but the gentlest conditioning formulas should be used. In such cases, professional hair colouring is often combined with restorative treatments.

Can I Achieve My Desired Shade in One Appointment?

Yes, provided that your chosen colour can realistically be achieved on your current base without complex colour removal.

Is a Sensitivity Test Required Before Hair Colouring?

If you are prone to allergies or are using a particular colour brand for the first time, it is best to carry out a patch test on the inside of your elbow at least 24 hours before the appointment.

Is Styling Included in the Price of Single-Process Hair Colouring?

This depends on the individual hair colouring salon in Kyiv. Light blow-drying or a full styling service may be included in the package or charged separately, depending on the salon’s price list.

When Can I Wash My Hair After Colouring?

It is best to wait 24–48 hours before washing your hair. This gives the artificial pigment enough time to settle fully within the hair.
