A must-have for hair prone to split ends and breakages, the Olaplex No.4 Bond Maintenance Shampoo hydrates and nourishes hair as it cleanses. The shampoo uses patented bond-building technology to improve hair's manageability, softness and visible strength.
Ideal for hair that has been exposed to frequent colouring, bleaching, chemical treatments and heat styling, the shampoo delivers moisture without weighing your lengths down and helps to protect against future breakage. Use daily or on every wash day as part of your Olaplex routine.
Suitable for all hair types.
Vegan.
- Application: Dispense the desired amount of product into hands and emulsify. Apply to wet hair, focusing on the scalp and working through to ends. Rinse.

Not good for my hair
I bought the Olaplex system: no 0, 3, 4 and five. The shampoo left an odd layer on my hair and left it feeling extremely dry. The conditioner I put on afterwards didn't do any difference. It left my hair drained from all moisture and my 3B curls were a complete mess, making my head look like a frizz ball. I am not trying or buying No 4 anymore.

Lifesaver
A little goes a long way and I can really feel the difference in my hair after using the olaplex system for a few months. A life saver for bleached, damaged hair when used alongside olaplex 3, amazing!

Incredible shampoo, highly recommended
Must be on my fifth bottle now, I have extremely thick coarse hair. I really struggle to find products that leave my hair soft and silky. This is the best I’ve ever used, it’s true what people say about these products. Doesn’t strip the colour and doesn’t leave my hair claggy. Unfortunately I go through a bottle a month but it’s well worth it for the condition it leaves my hair in. Olaplex Products have really kept my hair going this year during two lockdowns, at one point unable to go to the hairdressers for nearly 5 months. I can see why salons use them.

Instant results
My hair felt better from first application. I only need a tiny amount to lather up my thick long hair so it lasts ages (so not as expensive as it looks!)

Absolute fave
This has to be my favourite shampoo. Other shampoos can leave my hair dry and horrible. But this, combined with the conditioner and No6 Bond Smoother is an absolute treat for my hair. It leaves my hair soft, smooth and shiny. And I have the added bonus knowing that it’s repairing my hair. I also use the No3 Hair Perfector. It may be expensive but you know it will be worth it
