Description
Olaplex No.4C Clarifying Shampoo 1000ml is a professional, concentrated deep-cleansing shampoo developed to remove stubborn product build-up, excess oil, hard-water minerals and environmental impurities without unnecessarily stripping the hair. Powered by patented OLAPLEX Bond Building Technology and a Broad-Spectrum Clarifying System, this shampoo helps restore softness, shine and colour clarity while supporting stronger-feeling hair.
Unlike ordinary maintenance shampoos, OLAPLEX Nº.4C is designed for a more thorough weekly cleanse. It works to lift accumulated residue from the hair and scalp, leaving strands feeling refreshed and better prepared for subsequent conditioning and repair treatments.
The generous 1000ml bottle provides a convenient professional-size option for customers who regularly incorporate clarifying into their hair care routine.
Why Choose Olaplex No.4C Clarifying Shampoo?
Everyday styling products, dry shampoo, excess sebum and environmental pollutants can gradually accumulate on the hair.
Hard water can also deposit minerals that affect how the strands feel and appear. When this build-up becomes noticeable, hair may look dull, feel heavy or become more difficult to style.
Olaplex No.4C Clarifying Shampoo is specifically formulated to address these concerns.
The shampoo uses a Broad-Spectrum Clarifying System designed to remove several types of residue, including chlorine, hard-water minerals and styling-product deposits.
Its concentrated formula produces a rich lather while supporting the hair’s moisture balance.
The manufacturer’s patented Bond Building Technology complements the cleansing system by supporting the integrity of hair affected by everyday damage.
This combination makes Nº.4C particularly useful before conditioning masks and other repair-focused treatments.
Key Benefits of Olaplex No.4C Clarifying Shampoo
1. Professional Deep Cleansing
The formula provides a thorough cleanse, helping remove accumulated impurities that ordinary shampooing may leave behind.
It is particularly useful for hair regularly exposed to styling products.
2. Removes Product Build-Up
Styling creams, gels, hairsprays and dry shampoo can leave residue on the hair.
The broad-spectrum cleansing system helps remove these deposits, leaving strands feeling lighter and fresher.
3. Hard-Water Mineral Removal
Hard water contains dissolved minerals that may accumulate on the hair surface.
The shampoo is designed to help remove mineral deposits, including those associated with calcium-rich water.
4. Helps Remove Chlorine
For people who swim regularly, chlorine exposure can affect the appearance and feel of hair.
The clarifying system helps remove chlorine-related residue as part of a thorough cleansing routine.
5. Supports Colour Vibrancy
Product build-up and environmental impurities can make coloured hair appear dull.
Removing these deposits may help restore a clearer, more vibrant-looking finish.
6. Restores Softness and Shine
The manufacturer describes Nº.4C as a non-stripping cleanser that helps maintain softness while improving shine.
7. Bond Building Technology
The formula contains the patented OLAPLEX bond-building ingredient designed to support stronger, more resilient-feeling hair.
8. Suitable for All Hair Types
OLAPLEX identifies this shampoo as suitable for straight, wavy, curly and coily hair, across different strand thicknesses and porosity levels.
