Perfect for in between a gloss and permanent dye. 

We know that in the world of hair dye, things can easily start to get a little bit complicated. There are so many different ways to dye hair nowadays. You can go the demi-permanent route, add highlights, lowlights, semi-permanent color or permanent color. To clear things up about demi-permanent hair dye, in particular, we are breaking down the basics on this super common hair dye that can give some beautiful, glossy results.

Read on to learn all about this in-between hair dye:

What is demi-permanent hair dye?

Want to try out red hair but don’t want it to last forever? Use a demi-permanent dye.

Demi-permanent color is in between a semi-permanent and permanent hair dye. Typically, this type of dye can last anywhere from 12 to 24 washes before completely washing out. Demi-permanent dye lasts longer because it has a small amount of peroxide incorporated to open the outer layer of the hair. It allows the dye to partially penetrate the shaft, allowing it to last longer than a gloss. This type of dye works well for adding a darker color to your hair but because of the small amount of peroxide, it will not be able to lighten hair significantly.

Semi-permanent vs. demi-permanent vs. permanent: What’s the difference?

A semi-permanent dye is also sometimes known as a gloss. These dyes aren’t able to deposit color inside the hair shaft so they sit on top instead. This allows you to add gentle shine and radiance to your hair but only for six to twelve washes. Demi-permanent, as we said above, is the in-between sweet spot. It can create more color change and last longer than semi-permanent.

Lastly, we have permanent dye. This dye lasts the longest (as the name says, you’re stuck with it until your hair grows out) and can create the most color change. Permanent dyes will penetrate the hair, coloring it with a dye that won’t wash out. As opposed to semi and demi-permanent dyes, permanent dye does not always leave a gloss on top of the hair strand.

When to use demi-permanent hair dye

If you want to go for a subtly darker color change, go for a demi-permanent color. You can add color without doing a ton of damage to your hair and it will wash out soon enough. Blondes can really have the most fun with this because they can go darker much more easily than someone with already dark hair. Demi-permanent color is a good way to test out a fun hair color as well. Have you always wanted a red tint or purple hair? Get a good test run in with demi-permanent dye.

This dye is also good for blending gray hairs into the rest of your hair color. If you are just starting to go gray, or you are growing out a dark hair dye in favor of fully grey hair, demi-permanent dye is a good way to make the transition. Because it isn’t fully permanent, it isn’t going to have a harsh look as it grows (and washes) out.

Demi-permanent maintenance

When you use demi-permanent color, you’re already aware that it’s going to eventually wash out. You do want to make sure that your color isn’t washed out too early, though! When washing hair that has been treated with this type of dye, it is just as important to use color protective products as it is with permanent hair dye. And it’s even more important if you are going for a color that traditionally doesn’t last as long, like red hair dye.
