If you colour your hair blonde, hairdressers always recommend using a purple shampoo in your haircare routine. If you're curious about what purple shampoo is, or want to learn more about the benefits, we've rounded up and answered the most frequently asked questions about purple shampoo in a dedicated guide.
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. For blonde colour-treated hair, colour maintenance haircare products are the best way to prevent colour fading and extend the time needed between salon visits.
Why does your hair naturally turn yellow?
Unwanted brassy tones can appear for a number of reasons. The most common causes are sun exposure, chlorine and heat styling.
What are the Main Benefits of Purple Shampoo?
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 purple shampoo?
For best results, we advise using this product once or twice a week. Each induvial product will specify how long to leave on the hair, usually just a few minutes. If you apply the formula for longer than instructed, you risk the purple pigments disrupting your colour.
How long does it take to work?
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.
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.
