Product Overview

OLAPLEX No. 4 Bond Maintenance Shampoo gently cleanses while supporting hair vitality and strength.

This highly moisturizing, reparative OLAPLEX shampoo leaves hair easy to manage and looking shinier with each application. Proven to reduce breakage and strengthen hair of all types, this sulfate-free and color-safe shampoo eliminates frizz and flyaways for smoother, healthier-looking hair.

Key Features:

  • OLAPLEX's patented ingredient, Bis-Aminopropyl Diglycol Dimaleate, repairs damaged hair's disulfide bonds transforming brittle, dry hair into soft, manageable, shiny hair
  • Protects hair from daily stresses
  • pH Balance: 6-6.5

The white particles in the formula are soap that has solidified within the bottle and they rub in and wash away. We can confirm it is purely an aesthetic issue and that there is no impact to the safety or efficacy of No.4 Bond Maintenance Shampoo.

Note: At LovelySkin, we take your health and the health of your hair seriously. We have contacted OLAPLEX and spoken with their scientists about the recently announced issues. From statements by their scientists and CEO, it appears that there is no reason to believe that OLAPLEX products cause hair loss or hair breakage. Every OLAPLEX product is thoroughly tested by both their in-house formulators, as well as independent third-party laboratories. They use industry-standard Human Repeat Insult Patch Tests, also known as HRIPT, in which every OLAPLEX product is tested on humans to ensure it doesn’t cause skin irritation, inflammation or sensitivity. When hair products pass these industry-standard tests, it also means there is no caused inflammation to the hair follicle, which is a known cause of hair loss. If you are interested, you can read these findings on the OLAPLEX website.

Great shampoo for all hair types

I keep Olaplex shampoo & conditioner in my guest baths because it works well for so many hair types without it being too masculine or feminine of a product/bottle.

Good Shampoo...

I've been using this product for a couple years, which says a lot. I'm very particular about hair products a rarely make it through an entire bottle before I switch to something else. This consistentlyvworks for my hair. It isn't toi heavy, cleans effectively and doesn't contribute to frizz. I use it with other Olapex products and it's worth it.

Favorite New Shampoo

This shampoo is great! It's hydrating but leaves my hair feeling clean and fresh. My scalp can be a little sensitive but this doesn't irritate me. Smells amazing! The texture takes a little getting used to--it comes out a little thick--but just lather briefly in your hands and a little goes a long way!

Hair revitalizer

After using Olaplex No. 4 shampoo, my hair is less brittle and has more strength. My hair is so much smoother and retains moisture better - I don't need to use as much conditioner. The smallest amount of shampoo treats my entire mid-length hair which means that my shampoo lasts longer.

Happier Hair

In my mid 60s, I get my hair partially hylighted. Also my hair is curly. It tends to have dry ends. This shampoo and conditioner have helped to keep my hair softer and much less dry. I have also purchased their hair oil, and #9 along with #6. Check these styling products too. They help alot.

A little goes a long way

I have normal hair and bought this on a whim after all the hype. A little goes a long way, it lathers well, smells great, lasts a long time, and leaves my hair soft and manageable.

Absolutely favorite!

This is absolutely my favorite shampoo! It cleanses my hair well without over stripping it. Just a little lathers up nicely. High quality shampoo worth the price.

Lathers A Lot

I’ve been using this shampoo now for over 2 years. I like how much it lathers and makes my hair feel really clean. Even if the bottles small you don’t need much.

Helps smooth frizz when used with conditioner #5 and leave in bond smoother #6

Removed one star for packaging, have to leave upside down and it’s hard to open snap top. Good shampoo as part of total hair treatment of #4, #5, #6 products to reduce frizz and smooth hair.

Love this shampoo for my color-treated and thin hair

I've been addicted to this shampoo for the last two years. You need to use very little to make a big difference. Shiny, soft, moisturizing.
