Top 6 Best Ammonia-Free Hair Dyes: Reviews & Guide 2021

We hear so much about harmful chemicals and the toxicity of certain health and beauty products. How much of this should we take seriously and how much can we ignore? If you like to change up your hair color or are getting early signs of grey hair the easiest solution is at-home hair coloring.

It is important to know that some hair dyes can be extremely harmful to the structure of your hair follicle. Dying your hair consistently over time, breaks down the hair strand, leaving your hair brittle and weak. This can cause hair loss and breakage. The main ingredient in most off the shelf hair dye is ammonia. Ammonia is a chemical compound. The ammonia in hair dye forces the hair follicle to expand. Once the follicle has expanded then the hair is able to deeply absorb the color of the dye.

The splitting of the hair follicle to let in the dye is what ultimately weakens the strand causing breakage and permanent damage to your luscious locks. So how can you do your hair and reduce damage? The answer is in this article about finding the best ammonia-free hair dye.

What is ammonia-free hair dye?

Ammonia free hair dye is a hair color that does not contain the chemical compound ammonia. As explained previously ammonia breaks down the hair’s strength and should be avoided in hair products.

If a hair dye is ammonia-free it is not the same as a natural or organic hair dye. Ammonia free hair dyes often still carry some strong chemical, but without ammonia, it is much less damaging than products with ammonia.

Ammonia is not only harmful to your hair strength. The fumes that ammonia give off can be harmful to your eyes, lungs, and skin.

When dyeing your hair always go for an ammonia-free brand, as it is the best option besides natural, organic or no dye at all.

Is ammonia-free hair dye safe?

Let’s be perfectly clear here. We are not saying that ammonia-free hair dye is the safest option. The best option is to not dye your hair at all. Then the next best is natural henna or an organic dye.

Although if you are looking to permanently dye your hair, then make sure the dye you use is ammonia-free.

It is not the healthiest option, but it is the better of two evils. We all know to change the color of our hair causing damage to its health. The same occurs with blow-drying or straightening our hair. Both heat treatments will do damage to your hair, but we need to choose the option where the least damage happens.

When it comes to dyeing hair the least damage with best results is ammonia-free hair dyes.

Difference between ammonia and ammonia-free?

Very simply ammonia hair dye contains the chemical compound of ammonia which is harmful and damaging to your hair as it expands and weakens the strands to let the dye absorb deep into the hair.

Ammonia free hair dye does not contain this compound of ammonia but it will still contain other chemicals that help the dye absorb deep into the hair.

Many brands have come out with products containing a label of ammonia-free hair color. It is always important to know your ingredients as some brands simply replace ammonia with ethanolamine which is as harmful as ammonia.

If we compare ammonia hair dye against ammonia-free hair dye, the ammonia-free advantages out weight the disadvantages.

Advantages of ammonia-free hair dye

  • Less harmful to the hair strand
  • Keeps hair stronger
  • Permanent color finish
  • Avoid harmful ammonia fumes
  • No skin irritation or harmful effects

Disadvantages of ammonia-free hair dye

  • Still contains harmful chemicals
  • May not be organic or natural
  • May replace ammonia with other harmful ingredients

How to best apply ammonia-free hair dye

As mentioned before ammonia-free hair dye still contains certain chemicals in order to successfully color your hair.

This means that you should apply the best ammonia-free hair dye with the same caution you would any other hair dye.

Always do a skin test sometime before applying the hair dye. A skin test will let you know if you will have an allergic reaction to the product you are about to use.

It is also always a good idea to do a strand test. Take a piece of hair from the back under part of your head for the strand test. Apply the product as per the instructions on the box or packaging.

A strand test is helpful to see if the color is going to give you your desired result.

With any beauty product be sure to read the instructions thoroughly before starting the application process.

Always wear the gloves provided by the hair dye to protect your hands during application.

It is also always a good idea to apply Vaseline or a similar product to the edges of your hairline before attempting to color your hair. Best practices involve applying Vaseline along your forehead, and on the back of your neck and ears to avoid the dye transferring onto those areas.

Never use hair dye for eyebrows or lashes. The strength of hair dye differs from the strength used on eyebrows or lashes. Look to purchase a specific eyebrow and lash dye for those areas.


In conclusion, these are a great range of ammonia-free hair colors. If you need the cover of grey hair and have sensitive scalp or skin then the Herbatint is worth the money.

If you are looking to color your hair often and change it up, without the harmful effects then the Clairol is your number one go-to.

Looking to cover stubborn grey hair or unsightly roots, the L’Oréal is your best bet.

Either one you go for make sure it is ammonia-free and you carry out all tests before. Happy coloring!
