Hair Colouring Techniques: From Root Colour to Full Colour

TEO Kolorist16 January 2026 5 min read

All the techniques used in colouring, guidance on choice and colour protection.

Hair colouring is a personalised chemistry. The right pigment, oxidant percentage and processing time create perfect colour.

Root Colour

Covers the natural roots that appear 3-6 weeks after colouring. At TEO the same formula is recreated for consistent results.

Full Colour

The whole head is coloured to one shade. We craft custom formulas for guests changing colour.

Grey Coverage

Grey coverage requires special formulas and high pigment intensity. At TEO we use a specific oxidant combination for natural, lasting results.

Colour Protection

Do not wash hair for 48 hours after colouring. Sulphate-free shampoo and colour-protecting masks double the life of your colour.
