  • You shouldn’t dye your hair twice in one day with either permanent or semi-permanent hair dye.
  • If you use permanent hair dye, you could severely irritate your scalp and lead to hair breakage.
  • Alternatively, if you apply a semi-permanent hair dye twice a day, you’ll saturate your hair and the hair dye will drip for days.

Do you think that nothing like that will happen to you if you apply hair dye twice in one day?


Let me tell you the story of Pati, one of my clients.

Pati used to think that people tend to exaggerate. She considered that some websites advised not to apply hair color dye twice in one day to increase salon sales.

But she was wrong.


She was wrong, and her hair paid the price for her mistake.

So, remember,  you shouldn’t color your hair twice in one day. What’s more, you should avoid doing it with permanent hair dye  because it contains corrosive chemicals and skin irritants.


Pati had brown hair 4. She decided that as summer had arrived, it would be a good time to lighten her hair.

Since she would be enjoying a few days at the beach, she thought that she would get a summer blonde due to the effects of the sun and seawater.


She bought the kit by the model’s photo, a light blonde 8. Then, she followed the indicated procedure.

 When she washed and dried her hair, her nightmare  began deep into the night. Her hair looked different shades.

It looked as if she had taken a school paintbrush to brush a few strands.


When she regained composure, she had an idea. She would dye her hair again.

She ran to the drugstore and bought another coloring kit.

This time, not to take any chances with lighter shades, she decided on a light brown 5.


Again, she followed the instructions in the kit.

After 45 minutes, she rinsed her hair to remove the hair dye. When she blow-dried it, she smiled because the color looked good.


 However, after two days, she started noticing terrible hair loss. And not only when she combed her hair or took a bath. 

She also saw a lot of hair falling out on her pillowcase when she woke up.


After five days, and still alarmed by the hair loss, she noticed some white areas on her scalp and panicked. She felt that her scalp was burning.

Scared, she came to see me. In turn, I asked her to ask a dermatologist because I was concerned about her hair and scalp health.

Faced with such a scenario, the best thing to do is to ask a doctor.

Seven days later, Pati called me and told me what happened at the dermatologist’s office. Do you want to know what happened? Keep on reading.

What could happen to your hair if you dye it twice in one day?

after a bad keratin treatment

The dermatologist had found burns on her scalp because dying your hair twice in one day had affected the hair follicles.

As a result, her hair was falling out, and her scalp was irritated.


The white areas were the result of Pati’s scratching to relieve the irritation. She had injured herself, and the small wounds had become infected.

 Dyeing your hair twice in one day is too much aggression for both scalp and hair. 

It’s even worse if you choose a permanent hair dye.


When the scalp is irritated, it becomes swollen. The cells are defending themselves. When the scalp is irritated, the hair becomes thinner and more fragile. Therefore, it breaks and falls out.

The scalp loses nutrients, hence the white areas.


The dermatologist prescribed antibiotics to stop the scalp infection. She also forbade her to apply hair dye for at least six months.

Finally, she gave her some additional tips to soothe her irritated scalp from hair dye abuse.


How to restore hair damaged by hair dye abuse

I hope you don’t make the mistake of dying your hair twice in one day.

However, if you’re like Pati, who always goes against the tide, here’s a mask to soothe the first signs of scalp irritation.


Mask to soothe scalp irritation:


  • Two tablespoons of honey
  • One tablespoon of olive oil
  • ½ mashed avocado


Preparation and application:

  • Mix all ingredients until you get a creamy mix.
  • Apply it on the scalp with gentle movements, and leave it on for twenty minutes.
  • Then, rinse with cold water.


Honey is an excellent aseptic, and avocado and olive oil are natural nutrients to repair the dermis of the scalp.

But hold, there’s even more.


  • You should drink plenty of water.

It doesn’t matter if it’s water or natural juices or smoothies. The important thing is to nourish the body, and don’t forget that the scalp is skin.


Sensitive scalp after dyeing

  • Rinse your hair thoroughly every time you wash it.

It’s much better to do it with cold water. If you rinse your hair thoroughly, you’ll remove the residues that weaken the hair follicles, and prevent the growth of new hair.


This shampoo usually has soothing ingredients, it’s free of sulfates and parabens and it has only a few colorants and fragrances.


  • Opt for semi-permanent hair dyes. They contain less aggressive ingredients than permanent ones.

Don’t be stubborn. I’m guessing what you’re thinking.


Can I apply semi-permanent hair dyes twice in one day?

No. No way. Semi-permanent hair dye isn’t applied with a developer (one of the chemicals in permanent hair dyes) However, it’s not all that good.


You’ll probably leave a trace of color on everything you touch. It’s because the semi-permanent hair dye doesn’t penetrate the hair core.

It just sits on the outer layer forming a film of color.


When you apply too much semi-permanent hair dye, i.e. twice in one day, you saturate the hair with color. Therefore, the pigments come off and are deposited on your clothes, sheets, and towels.



You shouldn’t dye your hair twice in one day with permanent or semi-permanent hair dye.

  • In the case of permanent dyeing, you’ll put the health of your scalp and your hair at risk.
  • Also, in the case of semi-permanent hair dye, you’ll waste money and saturate your hair with color.

As usual, the decision is yours.


One last piece of advice.

If you want to correct any problems with the hair dye you just applied, ask a colorist beforehand. It’ll prevent you from damaging your hair so much that you’ll need to ask a dermatologist.
