The 11 Best Hair Dyes in 2025 – Top Rated Picks

Your hair is easily damaged and not as bright and healthy as you would like it to be? Nowadays, the number of treatments to which the hair is subjected ( hairdryer, plates, dyes are just a few) end up damaging it. But giving up on it is very tiring. That’s why we have to be very careful and try to improve the type of products we use on the hair.

A straightforward way to start doing it is to change our natural colouring products, choosing a hair dye instead. It might seem like a trivial matter, but you will notice a difference already after a few applications.

Here we had listed out some of the best quality hair dyes that are present below.

Buyer Guide to Choose the Best Hair Dyes

What do you think of our recommendations? If you are still not wholly convinced, in this section, we will answer the most common questions about this product.

After that, you will no longer have excuses to implement the change that will revolutionize the health of your hair and thanks to which you can show off always healthy hair.

Why Use Ammonia-Free Hair Dye?

If it is a matter of convincing you that abandoning the colouring you usually use and starting to use an ammonia-free tint is a smart choice, we cannot begin with any other question than this. Pay attention to all the advantages of this type of colouring treatment:

• Its ammonia-free composition does not harm the hair.
• It guarantees total coverage of white hair.
• As a result, your hair will be healthier and shinier, and together with this, you will also benefit from its excellent colouring power.
• It also has a pleasant scent.
• It is compatible with a straightening or keratin-based treatments.
• It improves the health of the foliage.
• As you can see, not containing ammonia, the tint does not penetrate the hair, but simply acts on the natural pigment. In this way, it protects the follicles, and the hair grows healthier and more energetic. In addition, ammonia-free dyes are more natural to eliminate than those that have them, which makes us comfortable if we like to change looks often.

What Types of Hair Dye Exist on The Market?

• Broadly Speaking, according to their duration, formulation and purpose, hair dyes can be divided into three broad groups:
• Permanent Colors: with long-lasting results and a more aggressive composition on the hair.
• Semi-Permanent Colors: they are mainly used to create a tone-on-tone colouring.
• Temporary Colors: wash off after a few shampoos.

Of the three types, the only ones that contain ammonia are the permanent shades. Consequently, whether we use semi-permanent ones or prefer temporary ones, it means that we already use a product which is ammonia-free in itself.

That’s why the only case in which to worry about controlling this aspect is the one in which we colour the hair with a permanent dye.

How Is a Hair DyeApplied?

Although it is increasingly common for women to colour their hair at home, there are still many who do not dare for fear of making a mistake or because they consider it a very complicated operation.

If this is your case, let me say you are wrong. In fact, the process of applying the hair dye can be summarized in seven simple steps:

First of all, prepare your hair. Make a shampoo; if possible, we recommend washing them the day before making the colour, to help the product fix better.

Now, it’s up to you to prepare. In order not to dirty everything (yourself included), wear “home” clothes and cover the surfaces close to where you will apply the colour with paper or a towel.

Obviously, take some precautions. Although the tint is ammonia-free, try to avoid it coming into contact with the skin as much as possible, also because it is quite challenging to wash off. So always try to wear gloves, which are included in most hair dye packs.

We come to the crucial moment: the mix. To mix products, always use a plastic container. Pour in the tint and oxygen, and be sure to mix them thoroughly.

To apply the tint, the simplest thing is to divide the hair into four sections. Apply the product on each of them, making sure to cover the entire area, from the roots to the tips.

Leave the product to act for the time indicated in the instructions for use. It is essential that you do not go beyond what is suggested because you could damage your scalp.

Rinse your hair with plenty of lukewarm water and wash it regularly. Never use boiling water, as it may lighten the colour.

Have you seen how simple it is? Surely now you will be less afraid of trying alone at home. In addition, all packs contain detailed application instructions.

In addition to following these indications, it also always takes into account those of the manufacturer brand, to make sure that there are not a few more steps to follow.

Do Hair Dye Guaranteed Satisfactory Results?

When we find a colour that we like and that works for our hair, changing our opinion is complicated. In fact, one of the main reasons why many women are still reluctant to switch to ammonia-free tint is because they tend to think that these offer worse, or less lasting, results than traditional shades.

Here: nothing more distant from reality. Although this myth has spread widely among hair colouring fanatics, those who have tried them know that ammonia-free dyes last as long as traditional ones.

Furthermore, the results can even be better, given that the health of the hair is not affected and therefore, the hair is more beautiful.

Can Dyes Cause Allergies?

The answer is simple: yes. In fact, all hair dyes can cause allergies, regardless of whether they contain ammonia or not. Just as dr. Josep Antoni López (Department of I + D in Farmatint), “there is a greater number of allergies to some types of dyes than ammonia.”

That’s why specialists always recommend that you do a test before using any type of hair dye. Just apply a little product on the skin, for example, on the hand, and leave it on for at least ten minutes. Then, we remove the product to check that no redness has appeared.

Purchase Criteria

Once the main concerns about the hair dye have been resolved, let’s move on to the practice. How to make sure you make a good purchase when buying one? Don’t worry, and it’s more straightforward than it seems.

You will only have to take into consideration the criteria that we show below and as if by magic, you will have in front of you the perfect ammonia-free tint for your hair.

• Type of tint and colour
• Quality

Type of Tint and Colour

Another factor to consider when buying is the type of tint we prefer. First of all, regarding this aspect, remember that we talked about the three main groups (permanent, semi-permanent and temporary) and that only the stable version contains ammonia.

Then, to choose the colour of your tint, it is essential that you are aware that no shade is the same on all hair types. Therefore there may be some small variations. If you are among those who do not like risks, follow the advice we have given you to choose the colour that best suits your characteristics.

Quality

We must also talk about the quality aspect. If we are looking for an ammonia-free tint to try to protect our hair and take better care of it, why then choose a product on offer? It wouldn’t make much sense, because, as they say, “the cure would do more harm than the disease.”

It is, therefore, essential to focus on prestigious brands in the sector since they offer us products that are a guarantee of quality.

Maybe the price will be a bit higher than the others, but in the long term, we assure you that it will be worth it because rebuilding a damaged canopy is a very time-consuming operation.

Conclusions

Are you tired of mistreating your hair, but don’t want to give up colouring? Then what you are looking for is a hair dye. The composition of this type of products, free of ammonia, is less aggressive on the hair and therefore allows you to show off a healthy, strong and shiny hair.

Furthermore, contrary to what is usually thought, the results and durability of the ammonia-free colours are the same as those of the traditional colours. Haven’t you tried them yet? Don’t wait any longer and join the colour revolution. More and more women are enjoying its benefits. Why not do it too?
