Purple shampoo is a blonde’s best friend. Whether your colour is au naturel or comes from a three-monthly trip to the salon, maintaining blonde hair is a task that needs careful practice. Ask any blonde and they will tell you that purple shampoo is the staple product in their haircare regime for maintaining their bright colour and keeping brassy tones at bay. But what actually is purple shampoo and how do you use it? We have all the answers right here.
IT PREVENTS YELLOW TONES
Purple shampoo works by neutralising brassy and yellow tones in the hair and there is actually a lot of science to it. Purple and yellow land on the opposite sides of the colour wheel, meaning they naturally cancel each other out. So, when blonde hair naturally starts to dull or yellow, purple shampoo is the product you need to bring it back to life.
IT CAN PREVENT DAMAGE
Yellowing in blonde hair, whether natural or dyed, comes from a number of different factors. Genetics can play a part in the development of brassy tones, but other factors such as pollution, smoke, sun damage and chlorine can cause golden blonde to turn yellow. A really good purple shampoo knows this and will often include ingredients to not only prevent colour fade but to also counteract the initial damage that has cause the discolouration.
IT KEEPS YOUR COLOUR SALON FRESH FOR LONGER
If your blonde is the work of a hair stylist, then you’ll be pretty pleased to learn that purple shampoo can actually help to keep your salon-fresh look salon-fresh for longer. Whether you have cool blonde hair that turns warm or white blonde that turns yellow, the neutralising pigments in a purple shampoo work to keep your blonde looking fresher for longer. If you’re a brunette with blonde or light highlights, purple shampoo can help to keep your lighter colour fresh without affecting the dark tones in your hair.
HOW AND WHEN SHOULD YOU USE IT?
As a general rule, purple shampoo can be used on most hair types once a week. If you’re new to the purple shampoo game, leave it on for one minute so you can get a feel for your hair’s reaction. If you have naturally dry or porous hair, your stands could hold onto the pigments a little more than you’d like, which could lead to your hair having a purple tint overtime.
The best time to use purple shampoo would be when you start to notice discolouration in your blonde. Using it before yellowing sets in might lead to your colour being lighter than what you originally intended. Trying your favourite purple shampoo once every ten days or once a fortnight to begin with, before increasing or reducing the frequency based on your hair’s reaction.
