Make the most of your blonde locks with the Olaplex No.4p Blonde Enhancer Toning Shampoo.
This unique shampoo has been made with all blonde, lightened, and grey hair types in mind, making it the ideal treatment for those wanting to banish any brassy tones. The formula itself is an update on the No 4 Bond Maintenance Shampoo and features an additional hardworking purple toner that leaves blonde hair looking brighter than ever before.
The shampoo is fortified with the brand's patented Bond Building Technology which results in stronger, longer hair that is soft to the touch. Additionally, it banishes the likes of any chemical nasties to ensure premium results that don't compromise the health of your hair.
Once applied, the shampoo gets to work on conditioning, toning, and strengthening the hair for that post-salon finish. We recommend following up with the Olaplex No 5 Bond Maintenance Conditioner for optimum results!
