Hair dye spray – “magic in a can” or is this a throw away culture?



There seems to be an increase in demand for hair dye spray cans by the world’s ageing population during the pandemic. There is a possibility that this demand is due to changing lifestyle where hair highlighting is now a more acceptable trend.

Whatever are the causes for this spike in demand there are many other factors restraining the market growth. The majority of manufacturers are still using toxic chemicals in their products that are causing skin/eye irritation and other long-term health issues.

Many governments and independent bodies are introducing stricter regulation associated with the use of chemicals and synthetics in the production of hair dyes. One such independent organisation is EWG Healthy Living. You can download their app to help identify and understand better the dangers of having chemicals in hair dyes.

Understanding hair dye sprays 

We live in an age where everything is a “quick fix’’. Whether it is to save lots of time or just to be the first in line, people do not have the patience.

Imagine waiting for 10 minutes just to get the colouring done to one’s hair! Hence the introduction of the hair dye sprays concept – use it, fix it and throw it away!

Hair dye sprays are only temporary hair colouring that coats the surface of your hair. The nice thing is it doesn’t penetrate the cortex of your hair. This implies it does not permanently alter your natural hair colour.

If your coloured hair happens to be damaged, it will be porous. This enables temporary hair colours to penetrate the hair shaft and stain your hair, ending up to be a more permanent colour instead.

Therefore the warning is to be careful if you have damaged or very light hair. If you do have damaged hair because over-dyeing make sure you nourish your hair follicles with nutrients to strengthen your hair with the proper shampoo and supplements.

L’Oreal spray cans are the most popular product on Amazon right now. Almost 30,000 cans sold so far due to some very slick marketing. I tested this product before the pandemic and must admit that it is a handy product to have in the cabinet for quick easy touch-up.

Today, even celebrities are claiming that this is the best temporary dye for root touch-ups.

Dubbed “magic in a can’’, reviewers are saying this easy to use spray covers all greys quickly and effectively within 3 seconds, which could be a fast drying time.

The product is promoted to be water-resistant with no sticky residue left behind. To remove the hair dye you should wash off with shampoo.

A bonus is that this product doesn’t have peroxide, ammonia or synthetic dyes. At least you don’t have to worry too much about the smell and possibly permanent damage to your hair.

For ladies, this aerosol is small and easy to carry around. It comes in eight shades – for black hair, brown hair, blonde hair and even red hair.


The biggest downside is that it still contains other chemicals such as Hydrofluorocarbon 152A, Butane, Ethyl Trisiloxane, Isobutane, CI 77499/Iron Oxides, Trimethylsiloxysilicate, Methyl Trimethicone, Triethoxycaprylylsilane E.I.L D179540/2. If you need to know whether these chemicals will do any harm to your body and the environment, check for details on the EWG website. 

EWG only highlighted two of the chemicals of concern. They are Butane and Isobutane which may irritate your skin, eyes or lungs if you inhale them.

If you don’t want a fire incident, keep the can away from direct sunlight or heat. Intentionally misusing by deliberately inhaling the contents can be fatal as well.

Useful tips

  1. Before you start dyeing your hair, it is advisable to wear latex gloves. While spraying, you can block your face with one hand and spray with the other.
  2. Spraying can be a bit of a learning curve because you need to adjust the distance and apply in short-burst or else you are going end up having hair dye everywhere, clumpy, wet and cold on your head.
  3. The dye has a flat colour and if your hair is shiny, it will likely turn it dull.
  4. Some other comments from end-users are that it does rub off with your fingers. I think this is because the dye is not evenly sprayed, making it too thick in some areas. Therefore it takes a little longer for it to dry.

My conclusion

Overall, it is an affordable quick option if you are unable to touch up your roots at your favourite salon.

Some brands are better than others in their application, ability to blend, price, fewer chemicals and longevity. Here is another popular hair dye – Style Edit Root Concealer Touch-up spray that is highly ranked on Amazon.

After spraying your hair, it will look thicker, refresh and shiny. There is little chance that the dye will run down your face even when you are sweating. End-users claimed that the dye will stick to your hair and will not be affected by wind, rain or sweat.

The dye can only be removed after your next shampoo. A good selling point is that this aerosol does have a build-in “gentle spray” which means you can aim directly to your roots without misfiring dye all over the place.


The dye spray comes in a small tin can and is considered more expensive than its competitors. It takes a lot to spray to cover all of your greys on-top of your head, especially if you are the type that shampoos often.

The spraying technique takes a little longer to master. Once you have done it a few times, it becomes easy to control where you want to spray. There have been reports on, that some end-users found their scalp itching after using the dye.

I would recommend that you “patch test ” for more than 48 hours to ensure there you are not allergic to the various chemicals in the product.


If you are not overly concerned about the various chemicals used in this temporary hair dye it is a good alternative product for your consideration. Other touch-up products available that you can look into, from Style Edit includes power and dye stick.
