Should You Wash Your Hair Before Dyeing It + More

 Before booking your salon appointment to change up your colour, it’s a good idea to familiarise yourself with what you can do to prep your hair to guarantee you’re getting the best new shade results- including, but not limited to, the question of when to wash hair before colour and if you should wash your hair before dyeing it. Here’s the down-low on what you need to know.


Colour rule number 1: don’t wash your locks

Right off the bat, answering the question of “should you wash your hair before dyeing it”, the answer is NO - it might feel logical, but resist that temptation, girl! The same answer applies to washing your hair before balayage or highlights and also the matter of conditioner. The bottom line: you should leave your hair dirty before any colouring process. Why? As any stylist will tell you, colour not only tends to hold better on dirty hair, but you’ll also have the natural oils on your scalp to help make the process smoother and the colour distribution more even- two things you definitely want during the dyeing process. Conversely, lathering up can make the colour process slippery, and leave your hair and scalp vulnerable to bleach- not ideal in anyway, and completely preventable by forgoing your wash before your colour!


Colour rule number 2: embrace the power of hair masks

The key to rocking a beautiful new shade comes down to the condition of your hair (but don’t get confused- the answer is still no to should I condition my hair before colouring). Healthy hair will keep the colour vibrant and shining for longer than dry or damaged locks. Before you colour, prep your hair with weekly hair masks like Kérastase Chronologiste Essential Revitalising Balm,a moisturising treatment for shinier, softer and bouncier hair. Apply the mask in the days leading up to your appointment at the salon in order to guarantee that your locks are ready for what’s to come, AKA gorgeous colour.


Colour rule number 3; choose your shade wisely

Bear in mind that going darker can be less damaging for your locks, as veering onto the blonde scale can strip your hair of colour and moisture, especially if using bleach. However if you’ve got your heart set on the lighter side of life, experts recommend getting a keratin, bond or olaplex treatment, especially if you're going lighter. This will help to seal in the colour, and make sure your hair is healthy enough to make your colour shine, without any damage in sight. Remember: it may take more than one session to get your colour where you want it, especially if going lighter. Patience is a virtue, but with gorgeous colour results, the wait is always worth it.


Colour rule number 4; protect your colour in the shower

After the colouring process, make sure that you're using a colour-safe shampoo and conditioner like Kérastase Reflection Bain Chromatique Riche Shampooand Kérastase Reflection Chromatique Riche Conditioner to protect your shade and keep fade at bay. In addition, if you’re going lighter, make sure you’re switching in a purple shampoo like Kérastase Blond Absolu Bain Ultra-Violet Purple Shampoo into your haircare routine, to keep brassiness at bay and your blonde shining for longer.



So, should you wash your hair before dying it? Absolutely not, if you want a hair colour to end all hair colours. Get your prep down to arrive at the salon as ready as you can be!
