So, How Long Does Permanent Hair Color Actually Last?

Permanent hair color can last anywhere between 6-12 weeks, depending on how porous hair is or what condition it’s in. It works by opening the cuticle and depositing color inside the hair shaft. That’s why it lasts until your hair grows out or when you recolor your hair.

Your choice of hair care products also has a big impact on the lifespan of your permanent shade, which is why a consistent hair care routine is essential for a glossier, longer-lasting color.

So, when you leave the salon, to get the longest wear out of your permanent color, apply color-safe hair care products consistently and prioritize protection, no matter if you’re using hot tools, heading out in the sun or hitting the pool.

What’s the Difference Between Permanent, Semi-Permanent and Demi-Permanent Color?

Semi-permanent, demi-permanent and permanent hair colors all interact with your hair in different ways, which affects how long your shade lasts and how intense it appears. Let’s take a closer look…

Permanent hair color deposits color molecules deep within the hair shaft. They do this by opening up and penetrating the layers that make up the hair cuticle. In doing so, they permanently alter the hair structure of the strands they touch (hence the name), so you get a long-lasting veil of your perfect shade with stunning intensity.

Demi-permanent hair color works in a similar way but the pigment doesn’t go as deep. It only slightly opens up the hair cuticle to deposit a small amount of color molecules inside. For this reason, demi-permanent colors tend to be gentler on your hair.

Semi-permanent hair color only tints the outer layer of hair. It doesn’t open the hair cuticle, so it has no effect on your hair’s internal structure. For this reason, they don’t tend to last as long as permanent or demi-permanent hair colors. You can expect your semi-permanent color to fade over 10-20 washes.
