Most leave-in creams simply coat the hair for temporary softness; Olaplex No.6 Bond Smoother goes deeper by supporting the hair’s internal bonds while it smooths. This concentrated, professional-grade leave-in is designed to control frizz for up to 72 hours, improve manageability, and help hair feel stronger with every use.

At the heart of No.6 is Bis-Aminopropyl Diglycol Dimaleate, Olaplex’s patented bond-building molecule that targets damaged disulphide bonds to support stronger-feeling hair. Nourishing oils such as grape seed, coconut and sunflower help condition and add shine, while panthenol and aloe leaf juice support softness and hydration without heaviness.

The formula is a silky, low-friction cream that spreads easily through damp or dry hair without leaving a greasy film. Hair feels smoother and more controlled, with a soft, satin finish that resists puffiness and frizz between washes. Once absorbed, it remains lightweight, so hair retains natural movement and touchability.

No.6 is designed as a leave-in styler that works from mid-lengths to ends to refine the look and feel of your hair. Use it before blow-drying to help speed up styling or on dry hair to re-smooth and refine. A little goes a long way, making it suitable for frequent use in a professional or at-home routine.

• Step 1. Start on clean, towel-dried or dry hair, ensuring excess water has been gently squeezed out if freshly washed.
• Step 2. Dispense a pea-sized amount into your palms, adjusting slightly depending on hair length and density.
• Step 3. Rub hands together and apply through mid-lengths and ends, focusing on drier, more damaged areas.
• Step 4. Comb or brush through to distribute the product evenly and detangle.
• Step 5. Style as desired, blow-drying for a sleeker finish or air-drying for a more natural texture.
• Step 6. On non-wash days, apply a tiny amount to dry hair where needed to smooth frizz and refine the finish.

Pro Tips

• Layer a drop of hair oil over No.6 on mid-lengths and ends for extra gloss and frizz control.
• Avoid the root area if your hair is prone to getting flat; keep product from mid-lengths down.
• Emulsify thoroughly in your hands before applying to prevent overloading any one section.
• Use sparingly at first and add more only if needed; the concentrated formula performs with a very small amount.
