Can I Put Purple Hair Dye Over Blue? A Comprehensive Guide

If you’re looking for a bold and vibrant hair color, there’s no doubt that blue and purple are great options.

However, what if you’ve already dyed your hair blue but now want to switch to purple? Can you put purple hair dye over blue? The answer is not a straightforward yes or no.

This blog post will discuss the factors you must consider before dyeing your blue hair purple.

Factors to Consider

Before you decide to dye your blue hair purple, here are some factors to consider:

  1. Current Shade of Blue: The first thing you need to consider is your hair’s current shade of blue. If your hair is a light or pastel shade of blue, it’s easier to cover it with a purple shade. However, if your hair is a darker shade of blue, it might be harder to achieve the desired purple color.
  2. Type of Dye: The dye you use will also affect the outcome. If you’re using a semi-permanent dye, it’s easier to cover up blue hair with purple. However, it might be harder to achieve the desired color if you’re using a permanent dye.
  3. Hair Condition: The condition of your hair is also an important factor to consider. If your hair is damaged, dry, or brittle, it might not hold the dye well, and the color might not come out as expected. Ensuring your hair is in good condition before dyeing it is important.

Steps to Dye Blue Hair Purple

If you’ve considered the factors above and still want to dye your blue hair purple, here are the steps to follow:

  1. Pre-Lighten Your Hair: If your blue hair is darker, pre-lighten it before applying the purple dye. You can use a hair bleach or lightning kit to do this. Follow the instructions carefully, and don’t leave the bleach on for too long, as it can damage your hair.
  2. Choose the Right Shade of Purple: There are different shades of purple, from light lavender to deep plum. Choose a shade that complements your skin tone and matches your style.
  3. Test the Dye: Before applying the dye all over your hair, test the strand to ensure the color comes out as expected. Apply a small amount of dye to a section of your hair and wait for the recommended time. Rinse it off and see if the color is what you want.
  4. Apply the Dye: Once you’ve pre-lightened your hair (if needed) and chosen the right shade of purple, it’s time to apply the dye. Follow the instructions carefully and apply the dye evenly to your hair. Make sure to cover all sections of your hair and avoid getting the dye on your skin or clothes.
  5. Rinse and Condition: After the recommended time, rinse off the dye with cool water until the water runs clear. Apply deep conditioning to your hair to restore moisture and prevent damage.


In summary, it is possible to put purple hair dye over blue hair, but the outcome will depend on several factors, including the current shade of blue, type of dye, and hair condition.

Pre-lightening your hair, choosing the right shade of purple, and following the instructions carefully can help you achieve the desired results.

Remember to take good care of your hair before and after dyeing it to maintain its health and vibrancy.
