The Best Ammonia-Free Hair Dyes

Ammonia-free hair dyes are an excellent choice for people with sensitive scalp or certain allergies, as well as for those who want long-lasting and shiny hair colour with minimal hair damage. Although it is not a new formula in the hairdressing industry, these products have become increasingly popular lately. In terms of covering grey hair, they have equally effective results as conventional dyes. What are the main advantages and disadvantages of these products? Which ammonia-free hair dyes are our favourites? The answers follow below.

To gain a better understanding of the advantages and disadvantages of different hair dyes, it is important to understand how they work.

Most permanent hair colours contain ammonia, a chemical compound that increases the pH value of the hair. This promotes the opening of the cuticle, allowing the dye to penetrate deeper into the hair shaft. This results in more intense tones and longer-lasting effects, as the dye stays on the hair longer. It also allows greater efficiency in covering grey hair. These hair dyes are a good choice for a drastic colour change, as they provide better results faster. They have a complex pattern of colours, making it easy to find the desired shade. However, constant and frequent use of ammonia-containing hair dyes can damage hair cuticles. This causes the hair to become dry and rough. It also loses its shine, breaks and tangles easily.

Additionally, ammonia has an extremely intense, pungent, and unpleasant odour. It can have a negative impact on the skin and hair of individuals with sensitive scalps and damaged hair, causing redness and itching. In extreme cases, if inhaled, ammonia can cause irritation to the throat, nose, and eyes. These reasons were the starting point for the technologists who created ammonia-free hair dyes. Ammonia has been replaced by appropriate, less harmful substances. These dyes are gentler on the hair and skin, have less colour penetration into the hair shaft, and therefore cause less damage to the hair.


Are Ammonia-Free Hair Dyes a Good Option for You

The first ammonia-free hair dyes were not particularly effective in covering grey hair, and the colour would fade more quickly. Most of these products initially had a semi-permanent effect and a limited tone palette. By constantly improving and refining formulations, these limitations have been overcome. A solution has been found, providing permanent results which guarantee 100% coverage of grey hair. Today’s ammonia-free dyes have high coverage power, long-lasting dye intensity, and a wider selection of shades.

A healthier and gentler formula for beauty products is always a better option. If you are in doubt about whether to replace conventional hair dyes (with ammonia) with ammonia-free ones, reconsider your habits and requirements. If you are sensitive to ammonia, frequently dye your hair (more than once a month), and want healthier and shinier strands without specific colour demands – these dyes are perfect for you.


Five main reasons to use ammonia-free hair dyes:

  1. They are gentler to the scalp and cause less damage to the hair;
  2. They have a much more pleasant smell than ammonia-based dyes;
  3. They give hair a healthier appearance, including softness, shine, and bounce;
  4. They can be used on chemically damaged hair;
  5. They provide a natural-looking hair colour.

To achieve the best results, always choose high-quality hair dyes. Check out our recommendations below.

If you are looking for an alternative to aggressive hair dyes and want to colour your hair with minimal negative impact on its health and appearance, and are not too picky about dyes and shades, ammonia-free hair dyes are an excellent choice.

They are not just a trend or marketing gimmick, but something that could become the only and permanent solution. With the constant focus on care and preservation of health, cosmetic companies are increasingly trying to eliminate ingredients that can be aggressive, seeking a gentler alternative. There is a possibility that in a few years, classic hair dyes which contain ammonia will no longer be in use.
