Is Permanent Hair Dye Actually Permanent?
You’ve been scrolling Pinterest and TikTok and finally found a hair colour that speaks to you. You’re already dreaming about your iconic look, but then a question comes to mind: how long does permanent hair dye last?At first glance, you may think the answer is, well, permanently! However, how long hair colour lasts depends on several factors, including the quality of the dye and the products you use for aftercare.As your hair grows, your roots will begin to show, and the initial colour you found directly out of the salon chair (or your bathroom sink) will change vibrancy. Proper aftercare is crucial to maintaining the hue you want.
How Long Does Permanent Hair Dye Last?
With most dyes, you won’t be able to maintain that initial head-turning colour without the right products. So, how long does permanent hair dye last?Generally, your hair will keep that glowing hue for the first 4 to 8 weeks. After this point, the length of time hair colour lasts will vary depending on your hair type, how often you wash, the water temperature, and which products you use.
Factors Influencing Longevity
Considering how long hair dye lasts before fading, 4 to 8 weeks is a wide range. This is because several factors influence how long hair colour lasts in its peak vibrancy.Permanent hair dye works by chemically altering the entire hair shaft. Healthier hair holds permanent colour more effectively. However, if your hair is dry, damaged, or extra-porous, it may lose vibrancy quickly.The colour itself also plays a role. Neutral tones like browns, blondes, and some reds are easier to reach from your natural tone. Conversely, fashion colours like bright purples, blues, and greens will fade quickly.A crucial factor is your aftercare routines. Permanent hair dye will fade if repeatedly exposed to water, heat styling, and some ingredients in shampoos like sulphates.
Average Duration of Colour Vibrancy
Overall, expect the 4 to 8-week range for your hair colour to remain vibrant. If you take care of your hair by following colour-treated hair care best practices, you can even go past that 8-week mark.By then, your roots will have grown out, so it’ll be time to refresh your hair dye. You could add a toner to restore the vibrancy to its original hue.The good news is that your hair will fade gradually with permanent colour. You’ll have plenty of time to schedule another appointment or touch up your hair before things become apparent.
Can You Make it Last Longer?
4 to 8 weeks is a great starting point, but is there a way to make it last longer?The answer is yes, provided you keep these tips in mind.
Best Practices for Hair Care Post-Dye
After taking the plunge and dyeing your hair, you want to ensure your hard work (and money) isn’t wasted.
Don’t wash for 72 hours after colouring: This will allow the colour pigments to set into your hair cuticle.
Use cold or lukewarm water: Hot water is like a master locksmith for your hair cuticle, opening it up and allowing the colour pigment to escape. Cold water will keep your vibrancy for longer.
Limit heat styling: Like hot water, the heat from styling tools will re-open your hair cuticle. If you plan to heat style, apply a heat protectant and use lower temperatures.
Glosses and toners in between dyeing: A colour-depositing toner will help you restore vibrancy. You can use it between trips to the salon.
Products to Prolong Colour Lifespan
The moment you dye your hair, your entire haircare routine changes. There are specific types of shampoo, conditioner, and treatments specifically formulated for dyed hair.Start by picking up conditioner and shampoo for coloured hair.

We recommend browsing our inventory of colour-care hair treatments for one that matches your new tone.With the right products and a consistent routine, your permanent colour will stay vibrant and salon-quality for months. Permanent dye is a fantastic option, but what if you want the colour to fade? In that case, semi- or demi-permanent colour may be a better fit. So, how long does semi-permanent hair dye last?
How Long Does Semi-Permanent Hair Dye Last in Comparison?
One of the critical differences between permanent vs semi-permanent hair dye is that the latter is made to fade away. Because it doesn’t penetrate the hair shaft, semi-permanent colour is a much lower commitment.So, how long does semi-permanent hair dye last?Expect semi-permanent hair colour to last around 4 to 12 washes at the maximum. Note that semi-permanent dye will disappear entirely rather than become dull over time. Semi-permanent dyes are a fantastic choice for a low-commitment look or fashion colours you don’t want to wear all the time.
What About Demi-Permanent Hair Colour?
If you can’t decide between permanent and semi-permanent hair colour, there’s a third fantastic option: demi-permanent colour!This type of dye lasts around 12 to 24 washes. It works by opening the hair cuticle to deposit the colour, but with lower levels of chemicals like ammonia or peroxide than a permanent dye. If you want to strike an excellent middle ground of how long hair dye lasts while retaining your hair health, demi-permanent is the way to go.
Which Type of Hair Dye is Right For You?

If you don’t wet your hair every time you shower, you can make it last more than a month.So, which one speaks to you best?
