What to do when your hair colour goes wrong

Most women know: colouring your hair at home can be risky. You need a professional touch to make sure the result is flawless. Have you tried to colour your hair at home and not been happy with it? Follow our advice from the pros to remedy the situation.
The solution obviously depends on what has gone wrong. “Tried to go blonde and instead ended up with bright yellow hair? You’ll need to lighten it again without colouring it again on top. You may have tried to go for highlights which didn’t quite take, or took too much on certain sections… This is because your base colour wasn’t well prepared. All of these errors can be rectified but you’ll need the opinion and expertise of a professional to do so. If your colour has gone wrong, head to the salon so that your hairdresser can identify the problem and rectify it.”
Whatever the reason for the error, do not colour your hair again on top. “This will not help matters. You will only make things worse and damage your hair. Sometimes highlights will suffice.  In a situation like this, the expertise of a technician is essential. He or she will be able to tell you which solution is best suited to your issue.”
The only colour treatment that you can try at home without taking risks is temporary colour. “This is a colour that washes out gradually. These colour treatments have few consequences and leave no trace on your base colour. If you don’t like the colour, you can get rid of it quickly.”
Our tip: the most frequent errors are those due to too much product being used. Result? Hair is the wrong colour and sometimes even turns green! At home, the only colouring solution you should try is temporary colour.
