However, you should respect the order of these steps to show off the purple hair you want.

So, without further ado, let’s proceed at Top Gun speed to dye your bleached hair purple without any problems.


Step 1: assess the condition of your bleached hair before applying the purple dye

Since we are warming up, my first tip is that   you wait three days to apply the purple dye after bleaching your hair.

Remember that bleaching is a very aggressive chemical process and your hair needs to rest.

After those three days, evaluate your hair health. You can perform the porosity test.

It’s a very simple test that can make the difference between beautiful or ruined purple hair.


  • Fill a glass halfway with room temperature water and place a hair strand in it.
  • After a few minutes, if the hair sinks halfway or floats, your bleached hair will resist the dye.
  • However, if the hair sinks to the bottom, you should not color your hair, especially with a permanent color.

My advice is to wait at least fifteen days to apply the purple dye on your bleached hair. In the meantime, apply intensive repair masks at least once a week.


Step 2: Choose a permanent or semi-permanent purple hair color

We already mentioned that bleaching is a very aggressive process that takes away nutrients and moisture. Therefore, you should choose a hair dye accordingly.

Permanent dyes contain chemicals and are applied with a developer.

Although the damage they produce is minimal, you’ll expose your hair fiber to another damaging chemical process.

Semi-permanent hair dyes, on the other hand, don’t contain ammonia and aren’t applied with a developer. So, they are less damaging to your hair.


If you skipped step 1, I pray you didn’t, take a look at your hair right now.

  •   If you notice hair in your comb, you have frizz, or you find it hard to detangle your hair when it’s wet,   you should apply a purple semi-permanent hair dye.
  •   Alternatively, if you notice that your hair isn’t frizzy and you can comb it without tugging,  , then you can apply permanent hair color. Remember to do the porosity test.

Step 3: Apply good-quality purple dyes on your bleached hair

You can find dozens of dye brands, but some are more effective and protective than others. They also have better quality pigments, which make the color last longer.

  • If you want to use a permanent purple dye, you can opt for GARNIER NUTRISSE, L’ORÉAL PREFERENCE and SCHWARZKOPF KERATINE COLOR.
  • If you want to apply a semi-permanent hair color, you can opt for MANIC MANIC PANIC, ADORE and PUNKY COLOUR.

These brands have a wide range of purple dyes.


Step 4: Prepare the place where you’ll color your bleached hair purple

To apply a dye as special as purple, you’ll need to take a few precautions.

The first thing you need to find is the ideal place. I recommend you choose the bathroom with appropriate light and enough space.


Forget about dyeing your hair in the garden or in a drafty place. Permanent dyes need an even temperature for the chemical reaction.

Also, keep old towels handy, and several sponges to clean up quickly if you spill a little dye on the floor or in the sink.

Lastly, always use gloves and old clothing.


Step 5: Your hair should be dry or damp according to the purple dye you’ll use

  • If you dye your bleached hair with purple semi-permanent hair dye,   it must be dry and clean.   Therefore, you should wash and dry it before applying the dye.
  • However, if you apply a permanent hair dye,   don’t wash your hair 48 hours before.   That way, the natural oil of the scalp protects your hair from the damage.

Step 6: Respect the exposure times recommended by the hair dye manufacturer

The exposure time varies according to the hair dye.

  •   If you choose a permanent dye,   leave it on for 45 minutes.
  •   If you choose a semi-permanent dye,   you should leave it on for 20 minutes to 60 minutes according to the intensity of purple you want to achieve.


Step 7: After the exposure time, rinse the purple dye with water

This is critical.   You don’t need to remove the purple dye by washing your hair with shampoo and conditioner.  

Instead, wash out the dye with cold water. Let the water run over your head until it runs clear.

If you have a permanent dye coloring kit, use the post-coloring treatment it includes. I advise you use it to rinse out the dye to nourish your hair.


  Finally, 72 hours after dye application,   you can wash your hair with sulfate-free products. Remember that sulfates are detergents that fade the dye and remove shine.



We focused on everything you need to keep in mind before and during the application of a purple dye on your bleached hair.

Remember that it’s very important to read the manufacturer’s instructions carefully to achieve a longer-lasting color.
