OLAPLEX® Nº.4P Blonde Enhancer™ Toning Shampoo vs. Nº.5P Blonde Enhancer™ Toning Conditioner: What's the Difference?

If you’re wondering what the difference is between purple shampoo and purple conditioner, you’ve come to the right place. Learn more about Nº.4P Blonde Enhancer™ Toning Shampoo and Nº.5P Blonde Enhancer™ Toning Conditioner, and see how these two products work together to brighten blonde, lightened, and gray hair.

Purple Shampoo vs. Purple Conditioner

Nº.4P Blonde Enhancer™ Toning Shampoo is a purple shampoo that gently cleanses, tones, and repairs your hair while keeping it hydrated from roots to ends. Purple shampoos like Nº.4P contain violet toning agents that seal in brightness and balance the tone of your hair, so if you’re noticing brassiness in your blonde or gray hair, you can kiss it goodbye.

Nº.5P Blonde Enhancer™ Toning Conditioner also contains violet toning agents to cancel out brassiness. But unlike Nº.4P, it contains shea butter in a lightweight formula to replenish moisture, nourish, and detangle your hair. You can also count on Nº.5P to hydrate, smooth, and add shine to your hair.

So, what’s the difference between these two products if they both brighten and reduce brassiness from your hair? Purple shampoo like Nº.4P helps cleanse your blonde or gray hair, while purple conditioner like Nº.5P adds extra hydration and smoothness. 

Do I Need to Use Nº.4P and Nº.5P Together?

On its own, Nº.4P neutralizes brassiness and yellow tones, all while repairing, strengthening, and hydrating hair. On the other hand, Nº.5P brightens, reduces brassiness, and adds shine. When used together, they deliver brighter, less brassy hair from the roots to the tips.

For the best results, it’s recommended that you use Nº.4P and Nº.5P together as a system. When used together, Nº.4P and Nº.5P are clinically proven to tone, strengthen, and smooth for shinier hair that’s 89% smoother with 52% less breakage after one use.* You also might see a 53% reduction in brassiness after one use.* And if that isn’t enough proof that they belong together, 91% of women in a study who used Nº.4P and Nº.5P as a system agreed their hair was less brassy.**

Do You Use Purple Shampoo Before or After Conditioner?

Like regular shampoo and conditioner, use purple shampoo before purple conditioner. To use Nº.4P, apply it to wet hair, lather fully, and leave it on for 1-3 minutes. For more intense toning, you can leave it on your hair for up to 5 minutes. Follow with Nº.5P, applying it from the roots to the tips of your hair for maximum toning, and let it sit for 1-3 minutes before rinsing. You can use both Nº.4P and Nº.5P 1-2x per week or as needed. For even more moisture, finish with Nº.8 Bond Intense Moisture Mask.

Nº.4P and Nº.5P are must-haves for those with natural or dyed blonde or silver hair. Learn more about how purple shampoos work or find more hair products for blonde maintenance.
