Be safe, be stylish. Your five-step guide to performing a skin patch test before dyeing your hair.

Step 1 – Choose a test area

Pick a suitable area on your body where the colour can sit for a while – this is typically either behind your ear or your inner elbow.

Step 2 – Wash and dry the area

Make sure your skin is fresh and clean, so there’s no risk of any contaminants affecting your test.

Step 3 – Apply colour to the area

Use a cotton bud to dab a small amount of hair colour onto your chosen test area and smooth it out to the size of a small coin.

Step 4 – Play the waiting game

Wait for 48 hours after performing your skin patch test to carry out a hair strand test to ensure no delayed skin reactions.

Step 5 – Wash and dry again

After the test period is over, simply wash and dry the area again to remove any hint of the hair colour.

What should I do if I experience any irritation after my skin patch test?

If you experience any itching, blistering, redness or swelling where you applied the hair colour, or you notice any kind of stinging or burning sensation, wash the colour off immediately and DO NOT apply the product to your hair.

However, if your skin patch test causes no negative reactions, then you’re all set to use Directions hair colour.

Do I need to perform a skin patch test if I've used Directions before?

Yes, you should perform a skin patch test before you apply Directions hair colour, even if you’ve used the product before. It’s an unfortunate truth that we can develop new allergies at any stage of our lives, so it’s important to always be safe and never sorry.
