The Olaplex No. 4P Blonde Enhancer Toning Shampoo offers stronger, softer, and brighter blonde hair with every wash. If you’re an Olaplex fan and your hair is blonde, white, grey or balayaged, there’s a good chance you’ve added this to your cart without even really reading the description. What we have here is a potent toning shampoo with all the magic (well, it’s science) that we know and love from Olaplex. Expect reduced damage and breakage and better colour on pale hair of all stripes. It’s also vegan, cruelty free, and made without sulfates, of course. 

One last thing to note: this is a toning shampoo that doesn't mess around. Work quickly to get it in your hair, and rinse your hands well.

First up, give your hair a pre-wash with your usual shampoo to remove product buildup and open your hair up. Then, lather a walnut or so of this shampoo through your hair and leave it to sit for 3-5 minutes. Rinse, and follow with either conditioner or a hair mask. Use weekly or whenever you feel like your hair needs brightening. Be sure to work quickly and rinse your hands - this is a strong and punchy purple shampoo.  

• Bis-Aminopropyl Diglycol Dimaleate, Olaplex’s patented ingredient which helps restore the broken disulfide bonds in damaged hair
• Violet pigments, to neutralise brassiness
