Full Olaplex No 4 Shampoo Review

Olaplex No 4 Shampoo is a revolutionary product designed to help restore your hair’s health and shine. Olaplex contains an active ingredient, bis-aminopropyl diglycol dimaleate, which helps repair any damage to the hair structure. This shampoo nourishes and repairs each and every strand from the inside.

The unique thing about Olaplex No 4 is that it helps prevent further damage to your hair by binding together broken bonds in the hair structure. This advanced technology helps restore natural shine and elasticity while protecting your hair from future damage caused by styling and environmental factors. Additionally, this shampoo helps improve your hair’s overall health, leaving it feeling soft and smooth.

The scent of Olaplex No 4 Shampoo is light and refreshing, making you feel refreshed every time you use it. This shampoo gently cleanses your scalp while moisturizing each strand from root to tip. It also helps reduce frizziness and flyaways while adding shine to your hair and making it feel super soft. Since its launch in 2020, Olaplex No 4 has become one of the most popular salon products for its ability to provide long-lasting results.

Olaplex No 4 bond maintenance shampoo is only available via professional salons and selected online websites. With its unique formulation and advanced technology, this shampoo will have your hair feeling soft and healthy in no time at all. Try it today for beautiful hair and colour results!

How To Use Olaplex No 4 Shampoo In Detail

This shampoo is designed to be used on wet hair. Wet your hair with lukewarm water, apply a small amount of Olaplex No 4 to your scalp, and massage it into the roots. Rinse thoroughly with warm water and repeat if desired. After you’re done, use a conditioner to complete the process. We recommend using the Olaplex No 5 (see table towards the end of the page), specially formulated to work with Olaplex No 4 bond maintenance shampoo. However, if you already own a high-quality professional conditioner, you can use that as well.

Olaplex No 4 Shampoo is a great product to try if you’re looking for an easy and effective way to restore your hair’s shine and elasticity. With its advanced technology and nourishing blend of ingredients, this shampoo helps protect your hair from future damage while giving it a soft and shiny look. If you want to go even further, we would recommend also blowdrying your hair with Olaplex No 7 Bonding Oil, however it’s not essential.

Ideal For Clients Who Bleach Their Hair

Olaplex No 4 bond maintenance shampoo is particularly useful for clients who bleach their hair as it helps restore their locks’ natural structure. The shampoo also adds moisture, which prevents breakage and makes brushing easier. It also provides a protective barrier against heat styling, ensuring your hair stays safe from damage. We have found this to be hugely popular with those with highlights, balayage or full head bleaching services. However, can you still use it if your hair becomes damaged from other chemical treatments, such as perms, relaxers or straightening services? The answer is yes!

What If My Hair Is Too Damaged For A Colour Service?

If your hair needs some serious TLC before you visit the hairdresser, Olaplex No 4 can help. If your hair is too damaged for colour services, this shampoo will work to repair the broken bonds and restore the natural strength of each strand. It also helps improve the overall manageability of your locks – you’ll find that it’s much easier to style and maintain them afterwards.

Why Doesn't My Salon Use Olaplex No 4 Shampoo?

While Olaplex No 4 Shampoo is a great product, not all salons use it. Many salons have specific contracts and agreements with other hairdressing brands. This is very common with some lifestyle spa salons, chains and franchises. However, if your salon doesn’t offer Olaplex, you can use the showcase links on our site and find out where to buy them at the best price.
