Sometimes your hair colour turns out differently from the one you desired. Your natural hair pigment may be the problem. It affects the chosen hair dye to show up as deeper or lighter colour than you wanted. Additionally, if your hair was already dyed or affected by other chemicals or some bad influences, such as sun, chlorinated water or pollution, that is certainly the reason for the unexpected colour shade. The good news is the knowledge about the colour wheel can help you fix this problem.
What is the colour wheel?
Although it sounds like a new age knowledge, understanding of light and colours dates from 17th century. It was Isaac Newton who distinguished rainbow colours and divided them into groups of primary, secondary, tertiary and warm and cold colours. The colours opposite each other on the wheel are called complementary colours. They neutralise each other. You wonder how does it work in practice? For example, if you have nasty yellow hues in your recently bleached hair, you need to use purple shampoo, as purple stands opposite the yellow in the colour wheel.
Bleached hair is really hard to nurture. Sometimes it’s not only the ugly yellow that shows up after a while but green, what’s even worse. The main culprit for that is the sun influence or pool water, which is full of chlorine and hard metals. Oxidization of these metals is, actually, the main trigger for the ugly green in blonde. Using the colour wheel knowledge, we can conclude that red hair toner can be helpful in this situation.
Brunettes have the most trouble when trying to change the original hair colour into lighter tones. Orange tones in their hair make them more prone to getting shades of this colour after a bleaching treatment. Again, what to do to get rid of them? – The colour wheel says BLUE, so if you have the same problem, use a blue shampoo twice a week and enjoy the desired look of your hair.
Can foodstuffs help in counteracting ugly hair hues?
The facts about the colour wheel teach us to counteract the green with a complementary colour – red. In the absence of proper cosmetics, you can use something red from your fridge – ketchup, for instance! Massage it into green areas and wrap your hair in tin foil for 30 minutes. The problem should be solved. Besides the colour, acids contained in tomato, as well as vinegar in ketchup, neutralise the chemical reaction that caused the problem in the first place.
Lemon can also help with it. If you decide to try, simply saturate your hair with lemon juice and let it sit for 5 minutes before washing. However, there is one fact that you need to know. This can help only if you are naturally blonde or have lighter hair basis. If your hair is originally brown or darker and has been bleached and dyed, the green can be neutralised only with red hair toner treatment.
