How Long Does Hair Colour Last?

dyed hair

Every month I think “This is finally the month I’m gonna dye my hair red”. But I never do. You see, I love red hair. It’s gorgeous and quirky, and I think it’d suit my colouring too. But what’s putting me off is the upkeep. In fact, the main reason why I stopped dying my hair blonde (which in hindsight wasn’t a good look at all!) in high school was that I was tired of having to go to the hairdresser every few weeks.

And let’s face it. If I can’t be bothered to have someone dye my hair every time it’s needed, chances are I won’t be that eager to do it myself at home.. Still, I thought it’d be nice to write a post about how long different types of hair dyes last for those of you who are thinking of dying their hair and aren’t as lazy as me. So, let’s start with highlights:


This is a technique that involves colouring only some hair strands lighter than their natural colour by wrapping them in foils to add both sheen and depth. Because the colour is applied only on some of your strands, there is no harsh regrowth line. This means that you can wait up to 6 or 7 weeks between visits. That doesn’t sound too bad, does it? Maybe I should go for red highlights, what do you think, lol?

Permanent Colour

Permanent colour allows for the greatest colour change. With this type of dye, in fact, you can go two shades lighter or darker than your natural hair colour. However, that also means that the regrowth will be very noticeable, so you’ll have to redye it every 3 to 5 weeks, depending on how dark or light you went and how fast your hair is growing. This can be quite expensive, but you can save money by redyeing only your T section (hairline and partline).

Semi-permanent Colour

Because semi-permanent dyes don’t contain peroxide or ammonia, they can only darken, not lighten hair. If you’re only interested in deepening your hair colour or want to see how a colour would look on you before committing to permanent dye, this is the best option. Semi-permanent colour washes out after about 8-12 shampoos (depending on how strong the formula is), so if you don’t like your new colour, you’ll have to put up with it only for 2 to 6 weeks. For the same reason, the regrowth isn’t too noticeable.

Of course how long your new hair colour will last also depends on other factors, such as how fast your hair grows, how often you wash your hair and how gentle your shampoo is, how much sun exposure you get… Still, these guidelines are useful to give you a general idea of what you are committing to if you decide to change your hair colour.

Do you dye your hair? If so, how long does your hair colour last?

    Do you ever read articles or find sales in stores and it’s exactly what you’ve been looking for? I have that with your blog, haha. This post is perfect for me! My dad and sister recently bought some henna to dye their hair. I’m not going to do it though but have you used henna?
    I love your natural hair color.

      Janessa, what a nice thing to say, thank you so much! That really made my day. :)

      No, I haven’t. I always went to the hairdresser whenever I wanted to dye my hair. I’ve considered using henna and other dyes but I’m afraid of the mess. I’m pretty clumsy so if I attempted to do it myself I’ll probably stain my entire bathroom lol.

      And thank you. :)
