  5. How to look after your colour-treated hair

Whether you’re a fan of platinum blonde, brunette, black, red, or you love a bold new colour trend (rainbow tresses anyone?), hair that’s been colour-treated needs a little TLC if you want it to stay looking fabulous and keep your colour longer. Nothing is worse than splashing out on a spectacular colour at the salon only to have it fade too quickly because you haven’t taken care of your mane.

If you want to keep your locks looking vibrant no matter how many weeks it’s been since your last appointment, we’ve compiled some essential tips to consider once you’ve dipped into the dye!

1. Wait 72 hrs before shampooing after colouring 

The colour-treatment process involves opening the hair cuticle to allow colour to penetrate the shaft. If you shampoo too soon, the colour can simply wash away if the cuticles are still open. You need to wait a full 3 days for the cuticles to fully close and seal the colour within the hair.

2. Sulphate-free shampoo and conditioner is a must

Whether it’s the first wash after your appointment or the tenth, it is essential to use a sulphate-free shampoo and conditioner for colour-treated hair. Sodium laureth ether sulphate is a common ingredient found in the majority of ordinary shampoos that helps to create the lather we are so familiar with. A harsh detergent, it can strip your hair of colour and its natural oils and moisture pretty fast.

If you want to sport your new hair colour for as long as possible, try using a sulphate-free shampoo and conditioner such as Kérastase’s Reflection Bain Chromatique Shampoo and Reflection Fondant Chromatique Conditioner to prolong and preserve colour radiance.

3. Don’t wash your hair every day

Washing even uncoloured hair excessively isn’t a great idea, but after you’ve had it colour treated, this applies more so. As well as washing away your natural oils that our scalps produce to keep hair healthy, it’s likely you will be washing away your hair dye much quicker also. If you want to see your bright colours last, try to keep it to 2–3 times a week.

4. Watch out for heating tools

Curling tongs and straightening irons are not ideal for colour-treated hair styling. The heat from these tools removes both colour and moisture which can damage hair. This does not mean that you need to avoid them altogether, but do use heat protectant sprays or creams before using hot tools or blowdrying to help reduce the loss of moisture from inside the cuticle and hold onto your colour.
Try Kérastase Nutritive Nectar Thermique Cream to nourish hair and protect it from blowdry and heat styling damage.

5. Keep up with Haircuts 

If you haven’t been having your hair trimmed regularly, now is a good time to start. Your ends are much more prone to splitting after colouring, so you must be sure to trim your hair every 6–8 weeks or sooner depending on how it grows to maintain its health and keep your colour looking as fresh as you can.

Now that you know how to look after your colour-treated hair, what are you waiting for! With the right post-treatment care, you can prevent damage and have locks that look as rich and vibrant as the day you stepped out of the salon. The important part is to take care of your hair and nurture it in the weeks following on from your colour.
