As we unravel deep into the magic of these colors, we unlock a world of endless possibilities. The vegan hair colors stay long enough but not too long. Let's dive deep into the world of quirky hair transformation. The blog details everything you need to know about temporary hair dyes.

What is semi-permanent hair color?

Semi-permanent hair colors are temporary hair paints that change the color of the hair but without a significant commitment. As the name suggests, it fades up after a couple of washes, leaving a window for experimenting with different colors. They coat just the outer shaft of the hair and do not penetrate the hair cortex.

The science behind semi-permanent hair color is quite simple. On application, it deposits acidic dyes on the outside of the hair shaft. As the color molecules enter the hair shaft, it forms a larger complex. As the temporary hair paints do not contain ammonia, it does not open the hair shaft for the color to penetrate. This helps with easy dislodging of the hair color after a couple of washes.

Benefits of using semi-permanent hair color

Demi_vs_semi_permanent_hair_colors There needs to be more clarity between semi-permanent and permanent hair color. Also, there is a demi-permanent hair color that needs some clarification. Let's demystify the names and tell you precisely what these are:

Step-by-Step Process of Application

Moehair's semi-permanent hair paint is rich, non-drippy, and easy to apply. Reading the information leaflet makes it convenient to use in the comfort of your home.

Here are the steps for the application of Moehair's temporary hair color:

Step 1: Pre-lighten

For the color to coat the hair shaft properly, it is recommended to first pre-lighten the hair up to level 7 or more.

Step 2: Wash your hair

After pre-lightening the hair, make sure to shampoo your hair. Always apply the color to clean, washed, and unconditioned hair.

Step 3: Wear gloves

Before pouring the hair color, wear protection gloves. Take the desired amount of the hair color into a bowl.

Step 4: Start application

Divide the hair into sections and secure each section with a clip. Start applying colors one by one on each section from root to top. Use an applicator brush for comfortable application.

Step 5: Wait for 30 minutes

After the application, let the color sit for 30 minutes before washing off. It gives enough time for the color to coat the outer part of the hair shaft. You might wait more, depending on the desired intensity.

Step 6: Rinse well

Rinse the hair with cool or lukewarm water. The semi-permanent hair color lasts for up to 10 washes and sometimes more. Do not shampoo immediately. If required, you can use conditioner after rinsing.

Aftercare and Maintenance Essentials


As the name suggests, these colors are not meant to last longer. However, with proper maintenance, it easily stays for up to 10 washes and sometimes even more.

Use a color-safe shampoo and conditioner

Always use a color-safe shampoo and conditioner to keep your locks shiny, lustrous, and healthy. Also, using deep conditioning hair masts once a week moisturizes the strands. You may even opt for a color-protecting primer for washing hair.

Avoid excessive heat

Do not use hot water to wash hair to prevent pre-mature fading of color. Hot water often dries out the scalp and strips the hair of its natural oil. It's best to use lukewarm or cold water. Also, use heat styling tools sparingly. Instead of using a blow dryer, let hair air dry naturally.

Reduce chlorine or harsh sunlight exposure

Limit your hair's exposure to chlorine or harsh sunlight. Wear a hat or headscarf when you step out to reduce exposure. Avoid swimming pool as it consists of chlorine, or use a head cover while swimming.

Avoid washing immediately

The cuticles take time to coat the hair dye around the hair shaft. Hence, to retain the hair color for a longer time, wait for 72 hours before washing with shampoo. However, rinse your hair after the application and let it sit for 30 minutes.
