  Are you planning to blow-dry your hair after dyeing or bleaching it?  


It’s generally possible to blow-dry both colored and bleached hair.

In fact, professionals usually finish a coloring job by blow-drying the hair for neat results.

However, I don’t want to fool you. The blow-drying technique seems very simple but, in fact, it’s not. First, stylists have special brushes for blow-drying. Secondly, we have very powerful blow dryers that don’t damage the hair if used by a professional.


Thirdly and most importantly, it’s not the same to blow dry a client’s hair as our own. Stylists work comfortably at the salon, especially in the back sections of the head, which are harder to reach.

There’s a slight difference between blow-drying after coloring the hair or after bleaching it. We’ll go into this in more detail.

If you bleached your hair at home and want to achieve those ’70s hairstyles that are back to stay, just wait.

First, we need to talk about bleach because it works with heat.

  Can you imagine what could happen if you didn’t rinse all the bleach out of your hair and start blow-drying?  


The heat from the blow dryer would activate the bleaching mixture and you could burn your hair.

The bleaching powder is very volatile; its particles are very small and stick to the cuticles. This is why rinsing out the bleach is one of the most time-consuming jobs in the salon during the bleaching process.

I’m not exaggerating.

Do you know how much time I spend rinsing the bleach mixture out of my client’s hair? Do you have time?


It takes   approximately 20 to 25 minutes to rinse the bleach.   It’s not a matter of running water through the hair.

It’s a job that requires a hair massage to activate the blood flow so that the hair expels the bleach. While massaging the hair, I rinse repeatedly and apply a conditioner to restore nutrients and moisture to the bleached hair.

Now, be honest with yourself: have you spent 25 minutes rinsing the bleach?


Then, I recommend you wait. Rinse your hair again; massage it from the ends to the roots with your fingertips. Let the water run for ten minutes and continue massaging under the water.

  After rinsing the bleach this way, my advice is to wait a few more washes.   Two will be enough. This way, you’ll definitely make sure no traces of bleach remain.

Finally, you can blow-dry your bleached hair and use a heat protectant.

If you colored your hair, you can blow-dry it immediately

  Remember to use a heat protectant and color protectant   because heat is the main enemy of colored hair. It opens the cuticles, evaporates moisture, and the color fades.


You can choose the heat protectant that is easiest for you to use. It could be a serum, cream, or spray.

Whether you have just colored your hair or applied the color several days ago, you need to use a heat protectant before blow-drying. Not only will you protect the color. You’ll also prevent your hair from being damaged by the dryer’s temperature.

Now, let’s explain what I promised at the beginning.


How to blow-dry colored or bleached hair like a real PRO

brush and dryer for blow-drying

To achieve perfect blow-dried hair, you must have:

  • Round brush.
  • Powerful dryer.
  • Room to move. I know you won’t dance, but I’ll explain why space is important.


Let’s start with the brush, which should be made of heat-resistant plastic and specially designed for blow-drying. It shouldn’t have natural bristles, as natural bristles melt and can burn your hair.

The bigger it is, the wider the blow-drying wave will be. Therefore, if you want the ’70s blow-dry style, you should have a medium-sized brush.

Smaller brushes will form curls and if you’re not very experienced, you could tangle your hair.


You should also have a powerful blow dryer. That means at least  4500 watts. You should have a blow-drying nozzle or duckbill , to concentrate the airflow on the hair.

It should also have three temperatures: high, medium, and cold to model the hair according to what you need.


Finally, enough space. In the salon, the stylist can move around the customer. At home, instead, you’ll need room to adjust your arms as you blow-dry your hair.

Now, let’s see the technique.

  •   The blow dryer should always be at 45 degrees and on top of the brush   for a perfect blow dry.
  • If you point it upwards, you’ll have volume, and if you point it downwards, you’ll have straight hair.
  • Comb through a strand of hair. When you reach the end, roll the hair into the brush.
  • Apply the blow dryer and unwind the strand.
  • Repeat several times.



You can blow-dry your freshly colored hair, but use a technical protectant to protect the color and health of your hair.

If you bleached your hair, I recommend you wait for two or three washes. This way, you make sure that your hair is free of bleach mixture residue.
