Quick answer: to make hair colour last longer, wash with a colour-protecting shampoo and conditioner, use cooler water, wash a little less often, protect hair from heat and sun, and refresh the tone between salon visits. Most colour fade happens in the wash and under UV, so those are the two places to focus.
Why does hair colour fade?
Colour molecules sit inside the hair fibre, protected by the cuticle. Every time hair is washed, heated or exposed to sun, the cuticle lifts a little and some colour escapes. Hot water, harsh cleansing, heat styling, UV, chlorine and pollution all speed it up. Reds and coppers tend to fade fastest, and blondes can turn brassy as cool tones wash out.
How to make hair colour last longer
1. Use colour-protecting shampoo and conditioner
Insight's Protective Shampoo and Protective Hair Conditioner won Best Shampoo & Conditioner for Colour Care at the HAIR Awards 2025. Organic macadamia oil, mango butter and grape seed oil soften and add shine, while henna extract adds antioxidant protection, so tone and highlights stay truer between salon visits.
2. Add a weekly colour mask
The Protective Hair Mask has an acidic formula that helps seal the cuticle and lock colour in. Leave it on for 5 to 10 minutes, once or twice a week.
3. Turn the water temperature down
Hot water opens the cuticle and lets colour escape. Wash in lukewarm water and finish with a cooler rinse.
4. Wash a little less often
Fewer washes means less fade. A dry shampoo like Bodifying Dry Shampoo refreshes roots between washes.
5. Wait after colouring
Many colourists suggest waiting a couple of days before the first wash after a colour service. Ask your stylist what they recommend for your colour.
6. Protect from heat and sun
Use a heat protector such as Replenishing Thermal Care Serum before styling, and keep tools at the lowest temperature that works. In summer, Protective Hair Spray helps shield hair from sun, sea salt and chlorine, with antioxidants that help neutralise the free radicals that fade colour.
7. Refresh the tone between salon visits
For blondes: award-winning Cold Reflections Brightening Shampoo and Hair Mask neutralise brassy, yellow tones. See all brassy blonde care.
For reds, coppers and silvers: Enhancing Color Pigments come in Bright Red, Fierce Copper and Rich Silver. They're ready to use with no activator needed, revive reflections, and fade gradually with no regrowth line.
Frequently asked questions
How long should hair colour last?
It depends on the type of colour, your hair's condition and your routine. Permanent colour grows out rather than washing out, but its tone still fades. Semi-permanent and direct pigments fade with each wash. Ask your colourist what to expect.
Does dry shampoo fade hair colour?
No. Using dry shampoo between washes means fewer washes, which helps colour last.
Is a purple shampoo the same as a colour-protecting shampoo?
No. A purple shampoo like Cold Reflections neutralises yellow tones in blonde, grey and lightened hair. A colour-protecting shampoo like Protective helps all colours fade more slowly. Many blondes use both, alternating them through the week.
Does porous hair lose colour faster?
Often, yes. Highly porous hair takes colour quickly but lets it go quickly too. Read our guide to hair porosity to find out more.
