How to dye roots at home like a pro

Even if it’s your first time, a salon-worthy result is within reach with the right root touch up technique. Here’s how to dye your roots at home for a flawless result:


Always perform an allergy test

Perform the allergy test at least 48 hours before dying your hair, even if you have already used colouring products before.


Protect your skin

First things first, you want to ensure you don’t end up with dye on your skin. To prevent this, apply petroleum jelly or a barrier cream along your hairline and ears.


Work in sections

Divide your hair into four quadrants using a hair clip or hair ties to keep each section neat. Apply dye to the roots one section at a time, working methodically from back to front to ensure even coverage.


Use the right tools

Swap those uncomfortable kitchen gloves for professional colouring gloves. All our Garnier dyes come with gloves included. Some dyes can be applied directly to the hair with your hands, others may need a tint brush and applicator for precision. Always read the leaflet for advice on the best application method.


Blend evenly

Apply to the roots and then gently comb the colour downwards to avoid harsh lines, this ensures you get a uniform colour from roots to lengths. For a softer, lived-in finish, apply a slightly darker shade at the roots and feather it into lighter lengths.


Grey root touch up

Grey roots can poke through quite quickly. Consult our handy guide on how to cover grey roots and hair for the best application techniques and results.


Timing matters

Follow the instructions closely. Leaving dye on too long or rinsing too early can affect colour payoff. If you’re using our Garnier Colour Retouch you’ll get perfectly covered roots in just 10 minutes.

Now that you know how to dye your roots at home, take a look at our full range of hair dyes to find the best shade for you.
