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!

Been looking for a clarifying shampoo my 4c hair would love and I would say olaplex is it. Lathers very well and you can feel your hair breathing again, it doesn’t dry the hair out while doing its job. It’s excellent for the price.

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 .

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

I used this to try get blue semi permanent hair dye to wash out it did fade a bit but not enough has i hoped it is good product but does dry hair out a lot unfortunately but nothing a hair mask cant fix

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!

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 👍🏼

Could notice and feel the difference after one wash! even my boyfriend noticed. Recommended to only use once a week, but after using I've only had to wash my hair once in between the weekly clarifying. So works out good value for money. Recommended.

★★★★★ 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
