If you have blonde hair, you may have heard about purple shampoo and how it can help to keep your colour vibrant.
Hair can turn yellow naturally, giving a brassy appearance. These unwanted brassy tones can appear for a number of reasons including sun exposure, chlorine and heat styling.
We are breaking down some common concerns and questions people have when introducing a purple shampoo into their routine. What we can tell you though, is once you've tried it, you'll never want to be without it...
What does purple shampoo do?
Toning the hair is essential when applying blonde colour, and purple shampoo is your at-home treatment to keep the colour looking fresh and vibrant. As purple is the opposite of yellow in the colour spectrum, purple-pigment shampoo draws out orange brassiness to reveal your perfect true blonde.
The main benefit is actively colour-correcting blonde hair to reveal a beautifully brighter tone, but some formulas also deliver deep cleansing action, defend against pollution, and hydrate. When used alongside a purple conditioner, these products work in synergy for the ultimate colour maintenance routine.
How often should you use a purple shampoo?
It's important to remember that purple shampoo should not be used every day as an everyday shampoo. Although they are brilliant at removing brassy tones, if used every day, they can cause your hair to take on a lilacy-grey hue.
We recommend using once to twice a week, instead of your usual shampoo to help upkeep the cool undertones of your locks.
Once you've rinsed the shampoo out, applied conditioner, rinsed again, and finished your blow-dry, you should notice a visible reduction in brassiness. By introducing this step as a weekly treatment, you can actively safeguard your colour and ensure that unwanted yellow tones are quickly lifted away.
As it is a toning shampoo, it can have a slight drying effect on your hair, so if you feel like your hair feels a little dehydrated, make sure to introduce hydrating hair masks, conditioners and serums into your routine.
Will purple shampoo stain your hair purple?
This is often the most asked question when it comes to purple shampoos as it's a major worry if you have blonde hair and don't want it to end up lilac!
Purple shampoo won't stain your hair as it washes out, but when used every day, it can cause it to become grey, which is why we recommend using only once or twice a week.
Can you use purple shampoo on non-blonde hair?
Purple shampoo is specifically formulated for blonde hair, highlighted hair, silver hair, platinum hair and ombre hair, as it balances the tones to boost colour vibrancy. However, if you're looking to eliminate brassiness from coloured brunette hair, we'd recommend introducing blue shampoo into your routine. Blue shampoo contains blue pigments which tone and brighten brunette hair.
