Now I am not the most creative person in the world, but I feel naming the purple shampoo by Olaplex N° 4P Blond Enhancer Toning Shampoo is a missed opportunity. Just think about it: The original Olaplex shampoo is called N° 4 Bond Maintenance Shampoo, so why not call it N° 4P B-l-ond Maintenance Shampoo? Am I the only one that would have found that hilarious?
But of course the name is just one of the things that interests us here. Even more important are how it works, how it makes my hair feel and if it is ultimately worth your money, so let’s talk about that!
And if you are curious, here is a video review of both this one and the Olaplex N° 4C Bond Maintenance Clarifying Shampoo:
What the Olaplex N° 4P Blond Enhancer Toning Shampoo claims
Highly concentrated purple shampoo cleanses, tones, and repairs while keeping hair hydrated from roots to ends. Sulfate-free formula creates a rich lather to neutralize brassiness and boost brightness after one use for all blonde, lightened, and grey hair.
Facts about the Olaplex N° 4P Blond Enhancer Toning Shampoo
Prize and size
One bottle – which is a beautiful lavender color – contains 250 ml and is available for 28.95 € on the website here. The shampoo is vegan.
Texture and smell
This shampoo is deep purple, and be warned, it will stain your tiles, your hands and your face when you apply it. That stain will wash off again, no permanent damage done, but the first time I looked at my purple hands I admit I was a little worried that they’d keep that hue.
Scentwise it smells the same as the other Olaplex products and has a regular shampoo texture. (More info: Olaplex and infertility – the facts?)
The lather it creates is rich and lavender in color.
How to use the Olaplex N° 4P Blond Enhancer Toning Shampoo
According to the website you should use this one 2-3 times a week, but that is about as often as I wash my hair in total, so again I use it less frequently than that, around once a week. That is enough to keep my bleached blonde bright, but you might need more if you have a very icy hair color or water that enhances brassiness more than the one in my area.
After using it my hair feels soft and hydrated, similar to how it does when I use the regular N° 4.

Like all Olaplex products this one contains Bis-Aminopropyl Diglycol Dimaleate, the ingredient aiming to repair the broken disulfide bonds. (More info: What is Olaplex and how does it work?)
On top of that there is a surfactant for cleansing the hair – interestingly enough it is supposedly harsher than the ones used in the Clarifying Shampoo, yet my hair still feels less stripped after using it, which once again emphasizes that formulation is more important than individual ingredients. Here there is added Glycerin, but other than that nothing more to benefit the hair, and of course the Olaplex fragrance mix including Limonene and Hexyl Cinnamal. (More info: Is fragrance in your products dangerous?)
Does it live up to its claims?
Yes.
It has a rich lather, leaves my hair hydrated and helps against brassiness with the first use.
Would I repurchase and which hair types do I recommend it to?
Let me preface this by saying: If you want the Olapex benefits for your hair, ask for it to be used at the hair dresser and get a bottle of Olapex N° 3 – some of the other products are lovely and staples in my routine, but really more of a nice to have in terms of hair repair than a necessity.
That out of the way: I can absolutely see myself repurchasing this one in the future. Yes, it is more expensive than a drugstore purple shampoo that will work just as well in terms of fighting brassiness, but it makes my hair feel less tangled with a much nicer smell, and for me that is worth the extra money. As I only use it once a week, I don’t think it will make much difference in terms of hair repair, but it surely won’t hurt either.
It is suitable for use in everyone with natural blonde, bleached or gray hair (More info: Why we go gray with age and why it matters)
