Drugstore Shampoos: Highlight Yellowing Culprits?

does drugstore shampoo yellow highlights

Whether you're a natural or bottle blonde, yellowing and brassiness can be a common issue. The solution? Purple shampoo.

Purple shampoos are called purple shampoos because they are—you guessed it—purple. The bold violet shade helps to neutralise any unwanted yellow or brassy tones in blonde, grey, or silver hair.

While purple shampoo can't replicate the work of a professional colourist, it can help to keep your colour looking fresh for longer in between salon appointments.

There are a variety of purple shampoos on the market, from budget-friendly options to luxury salon brands. Some of the most popular include John Frieda Violet Crush, L'Oreal Paris EverPure, Sun Bum Blonde Purple, and Kristin Ess The One.

Purple shampoo for blonde hair

Purple shampoo is a pigmented shampoo that neutralises and removes unwanted brassy, yellow undertones from blonde hair. It is essentially an at-home toner.

Purple and yellow are directly opposite each other on the colour wheel, so purple pigment helps eliminate yellow tones from blonde hair.

When hair is lightened, an undertone that hairstylists refer to as "raw blonde" is exposed. To get a richer, more quality blonde, hairstylists add a toner to eliminate any undesired undertones. However, these undertones can start to reappear as the toner fades, which is where purple shampoo comes in.

Purple shampoo should be used once or twice a week, as overusing it can cause hair to look darker. It can also be mixed with regular shampoo to incorporate some violet pigment into your regular hair-washing routine without going overboard.

Yes, purple shampoo is not just for colour-treated blondes. Natural blondes can also benefit from it, as brassy undertones can be caused by things like sun exposure, hard water, and heat styling tools.

When choosing a purple shampoo, it's important to consider not only how well it tones hair but also how well it protects and strengthens hair after lightening services. Some purple shampoos can be drying, so it's also a good idea to look for one with moisturising ingredients.

Purple shampoo for grey hair

Purple shampoo is a great product for maintaining grey hair, whether it's natural or dyed. It can help to tone and neutralise the hair, getting rid of brassy or yellow tones and leaving an overall cooler-toned look. The purple pigment in the shampoo neutralises the yellow and brassy tones in grey hair because purple and yellow are opposite on the colour wheel, so they cancel each other out.

How to Use Purple Shampoo on Grey Hair

There isn't a set schedule for using purple shampoo, and the frequency will depend on the shade you want your hair to be and a little bit of trial and error. It's recommended to start by using purple shampoo once or twice a week and then slowly building up from there if needed.

Purple shampoo should be left to soak into the hair for a few minutes, rather than being washed in and out quickly like regular shampoo. This ensures that your hair gets the full benefit of the product. It's best not to leave it on for too long, as it can be drying for hair, and it's recommended to follow up with a purple-toned conditioner to inject hydration back into your strands.

Purple shampoo for brassy hair

Purple shampoo is a must-have for anyone looking to maintain their blonde hair colour and keep it looking bright and fresh. It can also be used on grey hair to keep brassiness at bay.

Purple shampoo works by neutralising any unwanted yellow or warm tones in blonde or grey hair. On the colour wheel, purple is directly opposite yellow, so the purple pigment in the shampoo will cancel out any yellow or brassy tones in the hair.

Purple shampoo should be used once a week to twice a week at most. Overusing purple shampoo can cause hair to become ashy or take on a purple or grey tint. It's best to consult a professional stylist for advice on how often to use purple shampoo for your particular hair colour.

Purple shampoo for natural blondes

Purple shampoo is a must-have for natural blondes, helping to prolong your colour and keep your hair bright. It does this by neutralising any unwanted yellow or warm tones that can develop over time.

Purple sits directly across from yellow on the colour wheel, so purple shampoo will correct and cool down hair with a slight purple pigment.

This depends on the formula and the current colour and condition of your hair. Purple shampoos can be drying, so lathering up with a violet-pigmented wash two or three times a week is often best. Some formulas are gentle enough for daily use.
