Hair Colour Guide: Global, Highlights, Root Touch-Up and How to Make Colour Last

Whether you want to cover greys, add dimension with highlights or go for a full transformation, the right colour service and aftercare make all the difference.

Types of hair colour services

• Root touch-up – colours only the new growth, usually every 4–6 weeks.
• Global colour – one shade from root to tip.
• Highlights / balayage – lighter sections for dimension; balayage grows out more softly.
• Fashion colours – reds, blues, pastels; usually need pre-lightening.
• Ammonia-free colour – gentler on scalp and hair, slightly less long-lasting.

The process at the salon

1. Consultation – skin tone, current colour, past treatments and the shade you want.
2. Patch test and, for big changes, a strand test.
3. Sectioning and application (with pre-lightening if going much lighter).
4. Processing time of 25–45 minutes.
5. Rinse with colour-safe shampoo, conditioning or toning, then blow-dry.

Precautions you should not skip

• Patch test 48 hours before – especially if it is your first time or a new brand. Hair dye allergies can be serious.
• Do not wash hair on the day of colouring; natural oils protect the scalp.
• Avoid colouring right after smoothing or a perm – wait at least 1–2 weeks.
• Tell the stylist about henna use; henna can react with chemical colour.
• If you feel burning beyond mild tingling, ask for the colour to be rinsed off immediately.

Make your colour last longer

• Wait 48–72 hours before the first wash.
• Use colour-protect, sulphate-free shampoo and wash with lukewarm or cool water.
• Use a purple shampoo once a week for blonde or highlighted hair to remove brassiness.
• Protect hair from sun and chlorine.
• Book a deep-conditioning hair spa every 3–4 weeks – coloured hair loses moisture faster.
