- I don’t recommend leaving semi-permanent dye in your hair overnight. Although semi-permanent dyes are less aggressive than permanent ones, they still have chemicals that must be used following the directions of the manufacturer.
- Also, no matter how long you leave the semi-permanent dye in your hair, you won’t get any extra benefit. I mean, the color won’t get any lighter or darker or brighter or anything.
- So, the best thing you can do for your hair is to leave the semi-permanent dye in just as long as the manufacturer recommends.
Some days ago I was asked a question that worried me: “What if I leave the semi-permanent dye in my hair all night?” one girl asked me.
My client’s question worried me because, although I’m not against people dyeing their hair at home, I consider it delicate to do weird experiments on their hair. What’s the need?
For example, leaving a semi-permanent dye in longer than necessary wouldn’t ruin your hair. But, what if it was permanent? It could ruin your hair permanently. Why?
I’ll tell you below the differences between one and the other.
Before you start, I invite you to consider the following: what do you want to achieve by leaving dye on your hair all night? Do you want a darker hair color?
No matter how permanent or semi-permanent the dye is, leaving it on overnight will not make it darker. Even if you leave it on for two days, you’ll end up getting the color you paid for at the store.
If you’re looking for a darker hair color, then, go ahead and choose a darker color. It’s that simple. You’ll spend a few extra bucks but I assure you that your hair will be grateful.
If you want a to have hair like straw, then leave the dye on all night and that’s what you shall get.

If so, I’ll give you some good treatments that you can do at home.

What happens if I leave a semi-permanent dye in my hair all night?
- Hair professionals recommend that the times specified by each brand are respected. There is a reason why laboratories detail them in their boxes. If they are not taken into account, we can cause an allergic reaction.
- Fortunately, semi-permanent dyes do not contain elements such as peroxide or other harmful chemicals. They act in such a way that they only deposit the colour on the outer layer of the hair, without modifying its internal molecular structure.
However, keep in mind that if you want the dye to last longer, or its color to be super intense and bright, even if you leave it a thousand hours, both color and its durability will be exactly the same. Instead, you would only be risking a possible allergy.
What happens if I leave a permanent dye all night?
- Here’s where it gets complicated: permanent dye includes chemicals that are aggressive to our hair fiber, such as peroxide, which opens up our hair cuticle for pigment to cling to the middle layer, called Cortex.
Without beating around the bush, you must understand that if you leave this product any longer, you will only make it dry out completely, damaging its structure. Your hair may even start to fall.
- If you plan to leave it longer for color to last longer, let me tell you that you are making a big mistake. The only thing you will achieve is to wash it faster, since the cuticle will be under the effect of peroxide opening it more than it should, and it will become saturated.
Other consequences can be loss of strength and gloss. Is that what you want? I’m sure not, so I think you’ll pay more attention to the instructions from now on.
