If you have experienced an unpleasant, strong itchiness after having your hair coloured, it could be because your body had a reaction to certain ingredients of hair dye.
What causes reactions to hair colour?
The usual suspects for this kind of reaction are PPD (paraphenylenediamine or p-phenylenediamine) and PTD (para-toluenediamine). They are commonly used in most modern permanent hair colours and they are essential ingredients for the oxidization process required to bond the colour on the hair.
Does it affect many people?
Less than 2% of people usually have any reaction to these ingredients. And of those who do, very few will actually have an allergic reaction. So, if you had some type of reaction, it may not necessarily mean that you had an allergic reaction. Actually, approximately just 0.1% of all people may develop allergic reactions to those ingredients.
What causes the allergy to hair colour?
The interesting part is that the first times that you have coloured your hair you probably didn’t get the reaction. That is because your body was getting exposed to these substances for the first time. Your body then registers these substances as a threat which is why your immune system causes the allergic reaction. The substances are actually harmless, but it’s the reaction of your immune system that puts you at risk.
Wella Innosense could be a good solution to hair colour reactions.
Wella had been working for more than 20 years on a new molecule that would replace PPD and PTD – the main suspects for skin reactions to hair colour. And they finally came up with ME+, a molecule used in their Wella Kolleston Perfect Innosense range of hair colours. This molecule is much less likely to trigger a reaction from your immune system and that is why it has been awarded the first ever European Centre for Allergy Research Foundation (ECARF) seal on permanent colour.
Do I need to have an allergy test?
You can still get a reaction from this line of hair colours but the possibility is greatly reduced. As with any other hair colour, a skin test is required at least 48 hours before any application. This allergy test should be refreshed if you had successfully coloured your hair in the past but haven’t coloured it again for a long period.
Is the range of shades the same as with the other colours?
The range is more limited compared to other hair colours but covers most of the popular shades. A qualified colour specialist can mix the shades intelligently to achieve a wider range of shades.
I ‘ve never had a reaction to hair colour before. Should I use Wella Innosense?
It is really up to you. Using Wella Innosense instead of the other mainstream professional permanent colours has been proven to minimise the possibility of getting a skin reaction in the future.
