Nº.4C Bond Maintenance™ Clarifying Deep Cleansing Shampoo | Removes Damage Causing Impurities & Buildup | Restore Shine, & Softness | For Coily, Curly, Straight, and Wavy, 250mL / 8.5 Fl. Oz.

This clarifying shampoo has definitely given my locks a flippin good clean. Which is what I wanted. I followed it up with my existing different brand deep conditioner, as I think without it my hair would have been too dry on the ends. It was so squeaky clean! Hair soft and shiny. It’s not the type of shampoo to use regularly (well for me anyway) but will use every few weeks as a deep clean to get all the products out. Great stuff!

Hair feels really clean after using, expensive but works, lasts ages I only use once every couple of weeks to remove buildup

This shampoo has truly transformed my hair and scalp health, and I feel compelled to share my experience. For years, I struggled with dandruff and the challenges of maintaining my extremely long hair. However, from the very first use of this shampoo, I noticed a massive difference. Unlike the drugstore products I had been using, this shampoo completely eradicated my dandruff, leaving my scalp feeling refreshed and healthy. But the benefits didn't stop there. My long hair, which often felt unmanageable and lackluster, has been restored to a state I hardly recognized. It's now strong, silky, and voluminous, with a natural shine that I thought was impossible to achieve. The improvement in both scalp and hair health was evident immediately, and I couldn't be more impressed with the results. Yes, the price point is higher than what you'd find in typical drugstore brands, but the results speak for themselves. This shampoo has not only solved my dandruff issues but also enhanced my hair's overall health and appearance in ways I didn't think a shampoo could. It's worth every penny for the confidence and joy it has brought back to my hair care routine. A solid 5-star recommendation from me!

I use a lot of products on my hair, this shampoo is brilliant . It removes products bringing life back into your hair , without stripping colour. My hair is now manageable and shiny. This shampoo is a little expensive but well worth the money .

It cleanses the residue from products on your hair. I use it once per week followed by the mask. My hair feels glossy once again

Really good for taking product build up off the hair. Softens and only need to use a small amount. Great product

A bit pricey but well worth the £ as you need only to use a small amount per wash. This premium shampoo is gentle and effective at giving a thorough ‘deep clean’, getting rid of the inevitable build up you get when using multiple hair products. It lathers well, has a mild pleasant smell (not overly fragrance, which I prefer), leave it on for a few minutes before thoroughly rinsing. The results are impressive - beautifully clean, shiny hair 😊 Treat yourself 👍🏼

I have straight hair and oily skin/scalp, I have used this weekly since end of November 2025, it’s now mid-April and have only used quarter of a bottle, a little really does go a long way. For reference, my hair length is just past my shoulder blades. I do look forward to using it, as it really resets my hair and removes all buildup and excess oil! It’s taken a while for me to find something this good and will happily purchase again and again as it’s currently working well for me!

★★★★★ The Olaplex No. 4C Bond Maintenance Clarifying Shampoo is absolutely amazing! It delivers a deep, effective cleanse without stripping my hair, leaving it feeling fresh, soft, and healthy. If you struggle with product buildup or excess oil, this shampoo really makes a noticeable difference — my hair feels lighter and looks shinier after each wash. What I love most is that it clarifies and nourishes. Even with regular use, my hair never feels dry or tangled; instead, it feels smooth, silky, and revitalized. The formula lathers beautifully and rinses out cleanly, and the scent is fresh without being overpowering. Whether your hair gets weighed down from styling products or just needs a reset, this shampoo is a must-have. It truly delivers on its promises and leaves my hair looking healthier than ever! 🧖‍♀️✨💆‍♀️

Package was very dirty despite of repeated complaints nobody contacted very poor response

頭皮をとても綺麗にしてくれるのでありがたいです。 が、強いので毎週は使えないかも。ヘアマスクを一緒にするのがマストかな!

Fantastic shampoo, quite thick but cleans my hair really well, yet doesn’t leave it feeling dry. I use it about once a week as a cleanse from product build up!

amazinggggggg i love it
