Use deep conditioning masks.

The first step to keeping your plum hair color longer is using a deep conditioning mask. These masks are a great way to repair damaged strands, and they also work wonders on dry or dull locks. There are many key ingredients that make up the perfect plum deep conditioning mask, including avocado oil, coconut oil and lavender oil. Here’s how you can make one of your own:

• Put 1 teaspoon each of avocado oil and coconut oil into a small mixing bowl (or any other container that’s microwave safe).
• Add 5 drops of lavender essential oil then mix together with a wooden spoon until well combined. You’ll have created your own homemade deep conditioning treatment!
• Apply it directly onto damp hair after showering or washing with shampoo in sections from roots down to ends; let sit for at least 15 minutes before rinsing out thoroughly with warm water—no need for conditioner afterward!

Use sulfate-free products.

Sulfates are a detergent in shampoo that help clean the hair, but they can also strip the hair of its natural oils. When you rinse out your shampoo and conditioner, only then do you realize how much damage sulfates have done to your hair!

In my experience, sulfate-free products make a noticeable difference on how long my plum color lasts. I recommend using sulfate-free shampoos and conditioners as well as looking for other natural ingredients (like argan or coconut oil) in the product descriptions of your favorite brands.

If you want to keep your color longer, you should use shampoos and conditioners that won’t strip the hair of its dyed pigment.

The most important thing to remember if you want to keep your plum hair color longer is that shampooing too often can strip away the pigment. If you’re not careful, it’s easy to end up with a brassy or yellowish tint before your next appointment at the salon.

To avoid this problem, it’s best to use sulfate-free shampoos and conditioners that are paraben-free and silicone-free—in other words, products that won’t wash away any of your dyed color. Try alternating between washing with sulfate-free shampoos and conditioners once every two weeks (or even less) and using dry shampoo on days where you don’t have time for a full wash (or just prefer not doing so).

I also recommend using hair masks or oils every few days between shampooing sessions. These treatments will help keep your hair healthy while also boosting shine without damaging its hue in any way!
