The Truth About Permanent Hair Dye: How Long Does It Really Last?

There are a lot of myths and misconceptions surrounding permanent hair dye. Plenty of people think that after having their hair coloured, it will slowly return to its natural colour over time. In reality, depending on your hair’s pigment, the results can last from four months up to a few years.

What is Permanent Hair Dye?

Permanent hair dye is, as the name suggests, a type of hair dye that is designed to last for an extended period of time. Unlike temporary or semi-permanent hair dyes, which will gradually fade over time and need to be reapplied every few weeks or months, permanent hair dye will typically last for several months before it starts to fade. This makes it an ideal choice for those who want to avoid the hassle of having to regularly touch up their hair color.

Of course, nothing is truly permanent, and even permanent hair dyes will eventually start to fade and need to be touched up. How long this takes depends on a number of factors, including the quality of the dye, how often it is exposed to sunlight or other harsh chemicals, and how well you take care of your hair in general. In general, though, you can expect a good quality permanent hair dye to last for several months before it starts to fade noticeably.

How Long does it last?

Permanent hair dye is, well, permanent. It’s not going to wash out in a few weeks like semi-permanent hair color. So, how long does it last? The answer may surprise you…

Permanent hair dye will last until your hair grows out and you get it cut off. That means, if you don’t like the color, you’re stuck with it until your hair grows out completely and you can start fresh with a new color.

Now, that doesn’t mean your color will look perfect the whole time. Permanent hair dye can fade over time, especially if you wash your hair a lot or are exposed to sunlight frequently. But, as long as the color is in your hair, it’s not going anywhere.

So, if you’re thinking about permanently coloring your hair, just be sure you’re 100% happy with the color before you take the plunge!
