Hair coloring is one of the main parts of the work on your style.
Thinking about new hair color ideas?
Properly selected color, along with a haircut, revitalizes all the style, brings a touch of personality to it, and allows you to change at any time. The color dye can be different. Everyone knows that hair color is permanent and non-permanent.
But here is the main difference between permanent hair color from all other colors and what semi permanent hair dye is!
How long does permanent hair color last?
Permanent color means permanent.
Of course, there is no hair color that will ever change the color of your hair, so this term is used for the most persistent type of dye.
The basis of such dyes is ammonia, or its analog, a substance that allows the dye composition to penetrate deep into the structure of the hair and replace the existing color pigment with a new one.
In this case, the bonds between the molecules inside the hair are destroyed, and then new ones are built – it is due to this that the permanent hair color lasts so long.
How the permanent hair dye works?
Ammonia or ammonium hydroxide acts aggressively on the hair: it raises the scales of the hair, passing the coloring composition inside.
There are a chemical reaction of ammonia with hydrogen peroxide takes place, due to which the hair swells, and its natural color pigment is completely destroyed and replaced by pigment from paint.
Permanent coloring Precautions
Ammonia is incredibly volatile – that is why we all can smell permanent hair dye while visiting a salon or while dying at home, in the most exceptional cases, ammonia fumes can even cause an allergic reaction.
Therefore, in order not to get a headache, it is recommended to paint in a well-ventilated room – this also applies to cases of permanent dyeing at home, and when dyeing in beauty salons.
The composition of permanent hair dye, of course, irritates the skin of your head. However, you should check if you are allergic to one of the components of the dye.
To do this, apply the composition to a free area of the skin and wait for a quarter of an hour: if redness or itching occurs, it is better to refuse permanent dye with this composition.
Advantages and disadvantages of permanent hair dye
Modern compositions based on ammonia or its analogs are recognized as safe, but permanent paint has not only advantages but also disadvantages. Let us dwell on the pros and cons of such staining in more detail.
The advantages of permanent hair dye
- Persistent: color lasts up to 7-8 weeks!
- Coops with gray hair: 100% shaded gray hair!
- Vivid color: truly rich shades for every taste.
Cons of permanent hair dye
- Bad smell
- The need for a long scalp and hair rehabilitation period.
- It is difficult to repaint in a different color or return to a natural shade!

Permanent and semi-permanent hair color: what is the difference?
How long does semi permanent hair color last?
Semi permanent hair color is ammonia-free hair dye, and this is its main difference from the permanent dye. Semi-permanent hair dye contains hydrogen peroxide in small doses and less destructive ingredients as an activated peroxide.
Semi-permanent paint has a number of features:
- It is less persistent than permanent.
- The structure of the hair when stained does not collapse.
- No unpleasant smell during the procedure.
- Does not dye over gray hair 100%.
How long does semi permanent hair dye last?
Caring components are added to many semi permanent hair dye: thus, coloring turns not only into an style-making but also into a haircare event. For example, MATRIX Color Sync ammonia-free dyes contain a complex of ceramides that have a conditioning effect – it lasts up to 20 shampoo applications!
“Hair dye from the mass market category is a product that is designed in such a way that a person cannot harm himself and his hair. Salon compositions are designed for the professionals who can choose the desired oxide concentration (and, as a result, the color intensity) depending on the type of hair and the goals of a particular person.
The professional palette is much wider than usual – there are more shades, but also more nuances.
And another important quality of salon dyeing is that the stylist, mixing the hair colors, and can add various care components to it – again, depending on your hair needs. ”
Frequently Asked Questions
When we decide to dye our hair, we all want to be sure that the color will last as long as possible. However, many women ask whether permanent dye fades and if yes, how soon after being applied. Well, to clarify this question, we have prepared this FAQ list for you.
Will Permanent Hair Color Fade?
Even if you use high-quality permanent hair color, it will still start fading one day and there is nothing you can do with it unless using some preventive methods like shampoos or other care products with a color protective effect.
Why does it happen? Because our hair is exposed to different external factors like sunshine, UV influence, heat and moisture, and many others. And many of us do use those styling supplies like hairdryers and hair irons, right? And they are not so good to the hair color, too.
Is Permanent Hair Dye Damaging?
Probably, the most frequent question asked by women. The answer depends on the ingredients of your dye. If it contains ammonia and peroxide, it will be quite harmful to your hair and this is why.
Permanent hair color has stronger chemicals to make it last longer without fading which means that its influence on hair is also more intensive. Peroxide, for example, breaks your natural hair color whilst ammonia gets beyond the hair cuticle by lifting it up which damages hair badly.
Is Semi-Permanent Hair Color Safe?
Comparing to the permanent hair dye, semi-permanent one seems to be less harmful as it doesn’t contain harsh elements, ammonia, and peroxide, and also doesn’t get into the hair structure covering it only from outside.
One more advantage is that semi-permanent colors don’t last for long (maximum of six weeks).
Besides, now you can find various labels producing semi-permanent dyes that contain natural oils to protect and nourish your hair.
Can Permanent Hair Color Be Removed?
Despite its name, a permanent dye can be removed from your hair. As long as it sticks to your hair after oxidation, using reduction will help best. One of the ways to do that is to use ascorbic acid by mixing some lemon juice and clarifying shampoo.
The process to getting your best color starts even before you open your box. Here are a few things you need to know before you color.
DOES HAIR LENGTH AFFECT THE AMOUNT OF COLOR?
Yes. If your hair is longer than shoulder length or very thick, you may need two boxes to fully saturate your hair. Also, keep in mind that the ends of long hair tend to absorb more color, so the timing may be different for your ends. You may not need to apply color to your hair every time you color.
DOES HAIR TYPE MAKE A DIFFERENCE?
Hair type makes a difference in the timing of the coloring process. An important consideration is hair’s texture—when the individual hairs are coarse (large in diameter) or fine (small in diameter). Coarse hair generally takes more time to absorb color, so it requires a longer timing; fine hair generally takes less time to absorb color so it requires a shorter timing. Hair that’s dry or permed may absorb color quickly too. Because several factors affect timing, we recommend a strand test—it’s a good way to predict the coloring time.
SHOULD I CUT OR PERM BEFORE I COLOR?
Cutting your hair before you color will ensure you’re able to see the full effect of your color. And, of course, your color will enhance your cut.
The same goes for perms. Perm first to ensure that the perming process will not interfere with your newly applied color. If you’re using a Permanent hair color (lasts until your hair grows out or you recolor), wait 7-10 days and shampoo at least once before coloring.
Some Semi-Permanent (lasts though 8-12 shampoos) and Demi-Permanent hair color (lasts through 28 shampoos) can be used the same day as your perm—as long as your scalp is not irritated and is in good condition. Check the package instructions to be sure. Either way, make sure you do a stand test before coloring your hair. Perms and relaxers can leave hair more porous and allow color to be absorbed faster.
SHOULD I SHAMPOO BEFORE COLORING?
You generally shouldn’t shampoo immediately before coloring because this will remove the natural oils that protect your scalp during the coloring process.
It’s best to shampoo 12-24 hours before coloring with a Semi-Permanent (lasts through 8-12 shampoos) or Demi-Permanent product (lasts through 28 shampoos); shampoo 24 hours prior to using Permanent color (lasts until your hair grows out or you recolor). But be sure to check the instructions inside the box because it can vary by product.
CAN I MIX AND MATCH SHADES?
You can customize your shade to make it perfect for you. However, for best results, mix shades no more than 2-3 shades lighter or darker than each other. In other words, you wouldn’t want to mix a blonde and a black together. Also, you should mix shades from the same brand of color product.
WHEN SHOULD I START MY TIMER?
Set your timer for the amount of time indicated on the box as soon as you’ve finished applying hair color.
SHOULD I CONDITION AFTER COLORING?
It’s best to use the in box conditioning treatment that comes with your hair color. We give this hair advice because the conditioner that comes in the coloring package has been specifically tested for use with that hair color to help create softness and shine.
WHEN SHOULD I RE-COLOR?
Demi-Permanent hair color will last up to 28 shampoos—if you wash your hair every day, that’s about 4 weeks. Permanent (lasts until your hair grows out or you recolor) hair color should be refreshed when your roots start to show, about 4-6 weeks. As long as you follow the instructions for root application only, you should not have any problems with color build-up.
