OLAPLEX Launches No. 4P Blonde Enhancer™ Toning Shampoo

Well-known in the bond-building hair category, Olaplex has added a toning shampoo to its product selection No. 4P Blonde Enhancer Toning Shampoo is the first Olaplex toning shampoo to strengthen, soften, and neutralize unwanted yellow tones and deliver brighter, more manageable hair for blonde, lightened, and gray hair. Infused with Olaplex’s exclusive multi‐patented technology that relinks the disulfide bonds in the hair to strengthen and repair, No. 4P Blonde Enhancer Toning Shampoo cleanses, tones, repairs and protects while keeping hair hydrated from roots to ends.

Gentle enough to use every shampoo, this highly concentrated, customizable formula has been clinically shown to deliver bright results. It allows for customized toning—the longer you treat, the brighter the results. In a poll of stylists, 100% of respondents said they would recommend the shampoo to their clients.

“One in three women have blonde hair,” notes JuE Wong, Chief Executive Officer of Olaplex. “With the launch of our first scientifically proven and stylist approved purple shampoo, Olaplex expands the modern definition of blonde for noticeably hydrated, brighter, and more manageable hair.”

All Olaplex products contain the company's exclusive technology with more than 100 worldwide patents in the bond-building hair care category. This technology penetrates the hair shaft, working on the entire hair structure to rebuild the hair throughout and build a permanent bridge between the disulfide bonds. At the same time, it lessens and/or eliminates damage caused by molecules that eat protein from the hair by working faster than the damage can occur.


The Olaplex No. 4P Toning Shampoo formula:

  • Is sulfate‐free and non-drying
  • Forms a rich lather to neutralize brassiness and boost brightness after just one use
  • Is suited for blonde, lightened and grey hair, whether natural or stylist‐created
  • Can be rotated into any hair maintenance routine as needed

Since its founding, Olaplex has formulated products to be non‐toxic, cruelty‐free, vegan and free of more than 50 controversial ingredients including sulfates (SLS & SLES), parabens, phthalates and phosphates. All Olaplex products are carbon-neutral, and the brand is commited to reducing secondary packaging and not adding to its carbon footprint. 

The new shampoo can be followed with Olaplex No 5 Bond Maintenance Conditioner for everyday moisture or No 8 Bond Intense Moisture Mask for extra hydration. If hair has product buildup, the brand recommends cleansing first with No 4 Bond Maintenance Shampoo.
