How Long Does Semi-Permanent Hair Dye Last?

Semi-Permanent Hair Dye will last approximately 10-12 washes. However, the duration of semi-permanent color can vary from person to person, based on the overall health of your hair and its porosity.

The color will be at its most vibrant as soon as you’ve finished the application process, and over time it will gradually fade. Each time you wash your hair, the color will fade a little bit more. However, this is part of the process and your hair will still look fantastic as it starts to fade! The longevity of semi-permanent color is also highly dependent on your aftercare routine, so have a look at our tips on how to maintain your vivid hair. Please note, colors such as blue and green will typically take a little bit more time to fade.

Quick Tip: We recommend that you keep your hair out of the sun where possible as this will speed up the fading process!

How does semi-permanent hair dye work?

Unlike permanent products, semi-permanent hair dye does not penetrate the hair shaft to change its base color. Instead, it solely coats the outer surface of the hair which is a damage-free process. This involves color particles covering the outer layer of the hair shaft, without affecting the natural pigment. These color particles are so small that they will eventually be removed from the hair after washing it with shampoo (10-12 washes). Crazy Color Semi-Permanent Hair Dye has been created using a gentle conditioning formula which will leave your hair damage-free and hydrated.  

This temporary method of dying your hair opens up lots of exciting options and gives you the flexibility to change your hair color every couple of weeks!

Does semi-permanent color damage hair?

It simply coats the surface of the hair and it will wash out over time. This makes it a great choice for those who want to experiment with new colors, or like changing their look frequently.

Crazy Color semi-permanent hair dye products are formulated using our Rainbow Shield Technology which locks in moisture, leaving your hair feeling hydrated and healthy!

Will Semi-Permanent Dye Stain My Hair?

For the most part, no. Semi-permanent hair dye will not stain your hair and it will completely wash out after the appropriate number of washes (approx. 10-12). Semi-Permanent hair dye does not compromise the hair strand, it only coats the outer shaft. This means that given adequate time and washes, the color should be completely removed from your hair. However, if the hair has been dyed repeatedly, you may experience a very subtle stain on your hair.
