How Long Does Permanent Hair Dye Last?

Permanent hair dye is, as the name suggests, a hair colour that is designed to last until your hair grows out or you decide to change it. This type of hair colour typically uses an oxidative process to deposit colour onto your hair shaft.

The length of time that permanent hair dye will last depends on a few different factors, including the health of your hair, how often you wash it, what shampoo you use, and the type of hair dye you use. Generally speaking, though, you can expect permanent hair dye to last anywhere from 6 to 12 weeks.

If you have any concerns about using permanent hair dye on your hair, be sure to speak with a professional stylist before making the commitment. They can help you choose a hair colour that will be best suited for your hair type and give you some tips on how to care for your hair after dyeing it.

How permanent is it?

Permanent hair dye is, well, permanent. It permanently alters the hair’s structure, so it can only be removed with time –– new growth will eventually push out the dyed hair. Because of this, you should only use permanent hair dye if you’re comfortable with the colour you’ve chosen.

Of course, even permanent hair dye will fade over time –– though it will take several washes before you start to see any real difference. And if you’re looking to make a big change, expect to touch up your roots every few weeks.

So, while permanent hair dye may not be quite as low-maintenance as its semi-permanent or temporary counterparts, it does offer the longest-lasting colour. If you’re up for the commitment, permanent hair dye is the way to go.

Can you wash out permanent hair dye?

Yes, you can wash out permanent hair dye. However, it may take multiple washes to completely remove the colour. Permanent hair dye contains harsher chemicals than semi-permanent or temporary dyes, so it can be more difficult to remove. If you’re having trouble removing the colour, you can try using a clarifying shampoo or a colour remover.
