1 Get a patch test
A patch test makes sure that your skin doesn't react to the hair dye. A teeny smudge of the product will be applied to your skin, then you'll wait 48 hours to make sure it's a-okay. You can do this at any point before your hair appointment (just pop by your salon). Safeguard that scalp gang.

2 Time it right
A colour change can take a while (especially if you’re shifting from dark to light), so plan your time accordingly. There'll be no running out of the salon with slick wet hair, and a cloak still clipped ‘round the neck so you can make brunch. Rest up, and give your stylist all the time they need to work their magic.

3 Skip the shampoo
You should shampoo your hair at least 24 hours before your colour session, but never right before. That’s because ‘dirtier’ hair maintains the natural protective oil layer on your scalp, which acts as a barrier against the chemicals in hair dye. Healthier scalp, shinier colour, and you'll appreciate those sweet-smelling locks even more post-dye.

4 Find some inspiration
If you know you’ll struggle to describe your dream hair colour, don’t bother, just bring a picture in. Remember to be realistic though, just because your favourite blogger is sporting *that perfect* icy blonde, doesn’t mean your stylist can get you there in one salon trip.

FAQs
Why do you need a patch test before colouring your hair?
A patch test helps ensure your skin won’t react negatively to the hair dye. A small amount of product is applied to your skin, and you wait 48 hours to check for any irritation or allergy. This step keeps your scalp safe and your colouring experience comfortable.
When should you shampoo your hair before a colouring appointment?
You should shampoo your hair at least 24 hours before your colour session, but avoid washing it immediately beforehand. Slightly ‘dirtier’ hair maintains your scalp’s natural protective oil layer, which acts as a barrier against hair dye chemicals. This helps keep your scalp healthier and the colour looking shinier.
How can you show your ideal hair colour to your stylist?
Bringing a picture is the best way to show your desired hair colour if you’re unsure how to describe it. Visuals can help your stylist understand exactly what you want. Keep in mind that achieving certain colours, like an icy blonde, may not be possible in one visit depending on your starting hair shade.
How long should you plan for a major hair colour change?
Major colour changes can take a significant amount of time, especially if you’re going from dark to light shades. Allow enough time for your appointment so your stylist can complete the process thoroughly. Relax and be prepared to stay at the salon for the full process from start to finish.
