What is the best purple shampoo to use?

Do blonde’s really have more fun?

They can't always be the life and soul of the party. Any permanent blondie will tell you there's one major drawback to having lighter, brighter locks and that's the upkeep and maintenance. Maintaining bright, balanced blonde is not just what we do in the salon, its a full-time commitment, requiring regular toning, colour touch-ups and professional aftercare. How would you feel if Ritzy's told you there’s a cheat to banishing brassy tones and keeping your blonde looking salon fresh and radiant all year long?

The cheat lies with our best-selling range, Olaplex. Finally, after months of anticipation, Olaplex has launched their very own purple enhancing shampoo. Equipped with patented bond-building technology to fortify and strengthen damaged strands, Olaplex formulas are always big succesors in the haircare industry. And now, keeping blonde hair vibrant is easier than ever, thanks to the brand’s new No. 4P Blonde Enhancer Toner Shampoo. Enriched with concentrated pigments, the purple shampoo works to neutralise harsh yellow tones for renewed life and balanced colour. Blog:

What Is Purple Shampoo And How Does It Work On Blonde Hair?

All thanks to basic colour theory, the science behind how purple shampoo works is really simple. Remember learning the colour wheel at school? Well purple is the opposite shade of yellow, and this means that purple pigments can cancel out any yellow pigments in your blonde hair.

There are many colour correcting purple shampoos available on the market today, each one is formulated with varying intensities of violet pigment to help restore a cleaner and brighter blonde. Purple shampoo is also highly effective in banishing yellow tones in natural or colour treated grey hair.

How do I to use Purple Shampoo?

1. Apply purple shampoo to wet hair.

Always apply purple shampoo to wet hair instead of dry hair to avoid too much purple pigment depositing into each strand. Damper hair will also help you to achieve a better lather, even if you are using a sulphate free purple shampoo.

2. Leave the purple shampoo on for 2-5 minutes before rinsing.

Once the purple shampoo is applied, leave it on for anywhere between 2 and 5 minutes – When the allotted time has passed, rinse your hair with lukewarm water to close the cuticle and lock in the purple toning pigment.

Review by our customer Jasmine Sladder

“My highlighted blonde hair is always prone to losing its coolness after a few washes, I tried and tested the new Olaplex No.4p as I saw it on Ritzy’s Instagram and displayed in the shop. I usually really struggle on keeping my blonde hair vibrant. Since using the No.4p, my colleagues keep asking me if iv had my hair done! It really leaves you with that fresh salon feel and cool clear blonde everyone wants. A tad costly for a purple shampoo, but after seeing the results, Id happily purchase another bottle when mines finished.”

FAQ - Frequently Asked Questions

Can I use Olaplex 4P on dry hair?

Rinsing it off too quickly makes it less effective so Ritzys recommend applying it on damp, towel-dried hair as if you were applying a mask, combing it through evenly and leaving it on. About five minutes is the most effective.

Is Olaplex no 4P sulfate free?

No. 4 is a one-stop shop for almost any hair concern, from damage and moisture to hair growth and fullness. The ingredient line up in a bottle Olaplex is safe for all hair types, gentle, non-toxic, pH balanced, paraben free, color safe, vegan, sulfate free, cruelty-free, and SLS/SLES free.

How often should I use Olaplex 4P?
2-3x weekly

No. 4P Blonde Enhancer Toning Shampoo combines a high amount of pigment concentration with our patented bond-building technology & mild surfactants to provide a highly concentrated purple shampoo to deliver 3X brighter results (compared to top brands), yet gentle enough for frequent use (we recommend 2-3x weekly).

Is Olaplex 4P drying?

Purple Shampoos have a slight reputation for drying and dehydrating the hair. For this bottle blonde, Olaplex No. 4P is a no-brainer. The enhancing shampoo- non-drying, sulfate-free formula - contains OLAPLEX's signature bond-building technology—that penetrates hair to repair damage from the inside out, leaving hair feeling brighter and nourished at the same time.


To achieve the optimum results from this brightening shampoo, you should follow the instructions on the bottle. It’s also important to do a patch test inside your elbow or behind your ear and wait 48 hours to ensure you experience no skin irritation.
