1. Shampoo With Specialist Shampoo For Color-treated Hair
The most important thing to remember is to avoid using regular shampoo and conditioner on your hair. Colored hair needs products that are formulated specifically for it. That is because during the dyeing process, the hair is damaged and the cuticle (the surface of the hair ) can be chipped, making it appear rough or dull.
Besides, the natural protective barrier of the hair is damaged, it will allow hair color to leach out, fading with time. Ultimately, leaving you with less vibrant locks.
These color-safe products that are specifically formulated for color-treated hair can keep it moisturized and prevent the hair color from fading.
Another must-have product alongside a color-safe shampoo and conditioner is a moisturizing hair mask. The chemicals from the dye may leave your hair looking dry. A moisturizing hair mask will nourish your hair and make it soft, shiny, and smooth.
At the same time, don't use clarifying shampoo and sulfate shampoo, too. Although clarifying shampoo can deep-cleanse the scalp and strands of excess gunk and grime, this type of shampoo can remove the fresh pigment and tone of your hair. As the worst enemy of fresh color, sulfates will strip color molecules from the hair, leaving it dull and dry.

2. Wash Hair With Cold Water
Hot water will open up the hair cuticle possibly making more color leach out, thus making your hair look dull.
Be aware that the more time you rinse colored hair under hot water, the more it can lose its vibrancy. In contrast, cold water tends to help in sealing the cuticle.
Therefore, using cold water to wash your hair is a great way to protect colored hair.
If you want to take a hot shower, wear a shower cap to protect your color-treated hair from the hot water.

3. Condition Color-treated Hair
As we all know, dyed hair is more likely to become dry and brittle. So treat it with conditioners specifically formulated for color-treated hair, which helps create a protective barrier and also prevent your dye from quickly washing out.
Make sure to condition every time you shampoo, even if you have fine hair.
Or, you can try using a leave-in conditioner for even more of a moisture boost.

4. Dry Roughly With A Towel
Scrubbing too hard can fade color and make the ends look dry. Instead, gently blot your hair and let it air dry as much as possible.
If you must use a curling iron, flat iron, or blow-dryer, apply a heat protectant spray before using tools like your curling iron to keep from frying out your hair.

5. Do A Moisturizing Treatment
Color-treated hair can get dry and brittle, especially in the summer months. In this case, we recommend you apply a deeper conditioning mask or hydrating oil treatment like coconut, avocado, or grapeseed on processed hair and leave it on for 30 minutes or overnight to restore and keep hair strong.
