You may have noticed that we keep saying that permanent hair colour needs a catalyst. Permanent hair colour is any colour that can completely cover grey or make the hair lighter.
The catalysts role is to cause the hair cuticles to swell which will in term allow the colour to enter the hair cortex and in here oxidate and create permanent colour.
Temporary or semi-permanent hair dyes do not need to open the cuticle because the colour lives on top of the hair for a certain amount of time and then washes away.
This means that these hair colours do not contain ammonia nor MEA, but their effect is not long-lasting.
So, let’s make this clear: Our professional hair colours contain a minimum amount of chemicals to ensure lasting and covering results. Each shade of ours is composed of over 98% naturally derived ingredients. Head to our ingredients list and learn more.
MEA (Monoethanolamine/Ethanolamine) as an alternative to Ammonia is not a new thing. Not at all.
You will find that many ammonia-based hair colours also use MEA in addition to their ammonia.
Because MEA has been around for a while, it has also become a subject of some strong opinion – even dogmas – and they all centre around the molecule size.
You will hear this over and over again from Ammonia believers: MEA colours will fade fast…, MEA colours will give no shine, MEA colour does not close the cuticle… etc.
These were indeed true 20 years ago. But not today.
The amount of MEA in today’s MEA-based hair colours has rapidly decreased into a point where none of the above is even slightly applicable anymore.
With an average of 2% MEA, it will allow the colour to enter and oxidise, but also for the cuticle to close and deliver great shine and lasting results.
