Most clarifying shampoos leave hair squeaky, rough and vulnerable, while this one deeply cleanses yet respects your hair’s bonds. Olaplex No.4C Bond Maintenance Clarifying Shampoo resets your scalp and lengths, removing stubborn build-up without sacrificing softness, shine or colour vibrancy.

Powered by OLAPLEX Bond Building Technology, No.4C helps repair and support damaged disulphide bonds with every wash. A blend of clarifying surfactants, chelating agents and salicylic acid targets product residue, hard water minerals and excess oil. The result is hair that feels lighter and cleaner, while remaining protected against future damage.

The lightweight gel-textured shampoo lathers into a rich, cushioning foam that spreads easily from roots to ends. It rinses cleanly with no waxy film or rough, stripped feel, leaving hair refreshed, touchably soft and more manageable. Scalp feels purified while lengths retain a healthy-looking sheen and movement.

Use it as your weekly or bi-weekly reset when hair feels heavy, coated or dull. Focus on the scalp and root area first, then work through mid-lengths and ends to dissolve build-up evenly. Follow with a nourishing conditioner or mask to seal in moisture and leave hair at its smoothest.

Patented OLAPLEX Bond Building Technology helps support hair’s internal structure while you clarify.Targeted clarifying system addresses product, oil and mineral build-up in one step.Sulphate-free, pH-balanced formula cleanses effectively with reduced risk of excessive dryness.Helps optimise the performance of treatments, conditioners and stylers applied afterwards.

Use No.4C as a prep step before OLAPLEX treatments and conditioners so bonds and moisture can penetrate more evenly. It pairs especially well with No.3 Hair Perfector and No.5 Bond Maintenance Conditioner for a thorough bond-care routine from cleanse to condition.

A salon-level clarifying shampoo that deeply cleanses, supports bonds and leaves hair refreshed rather than stripped.

Pro Tips

• Double cleanse when hair is heavily coated with product, using a small amount each time rather than one heavy application.
• Emulsify the shampoo between your palms with a little water before applying for a more even distribution.
• Concentrate massage on the hairline and crown, where styling products and oils tend to accumulate most.
• Always follow with a hydrating conditioner or treatment to maintain softness and manageability.
