Remove the cap and turn the bottle upside down. Lightly tap the base with your index finger to release a measured drop, then apply 2–3 drops to damp or dry hair before styling as usual. You can use it daily on wet or dry hair, before heat styling for protection, or after styling to add extra shine and smoothness.
Olaplex No.7 Bonding Oil is more than a finishing oil. Its lightweight texture makes it a versatile step in your haircare routine, whether you want to soften dry ends, define curls, protect colour-treated hair or smooth fine hair without leaving it feeling heavy.
For Dry and Frizzy Hair: If your hair feels dry, rough or difficult to manage, apply 1–3 drops through the mid-lengths and ends. It helps hair feel softer, smoother and easier to style, without the greasy finish often associated with heavier oils.
For Curly Hair: Curly hair can use Olaplex Bonding Oil to help smooth frizz, boost shine and add definition. Warm a small amount between your palms, then scrunch it through damp curls or apply to dry hair to refresh and soften your style.
For Coloured Hair: Olaplex Bonding Oil helps add glossy shine while smoothing the look of dryness and frizz. It is a great finishing step when colour-treated hair needs extra polish and softness.
For Fine Hair: Olaplex Bonding Oil can work well for fine hair when used sparingly. Start with 1 drop, focusing on the ends rather than the roots, to add shine and smoothness without weighing the hair down.
Apply Olaplex Bonding Oil through the mid-lengths and ends of your hair, where dryness, frizz and damage are usually most visible. Avoid applying too much near the roots, especially if your hair is fine or gets oily quickly. Warm the oil between your palms first, then smooth it through the hair evenly before styling.
Start with 2–3 drops of Olaplex Bonding Oil, then add more only if your hair needs it. Fine or short hair may only need 1 drop, while thick, long or curly hair may need a little more. A little goes a long way, so it’s best to build gradually rather than applying too much at once.
Yes, you can use Olaplex Bonding Oil on dry hair. It works well as a finishing oil to smooth flyaways, soften dry ends and add shine after styling. Apply a small amount to the mid-lengths and ends, focusing on areas that look frizzy, dull or dry.
Yes, Olaplex No.7 Bonding Oil can be used before heat styling as a styling oil that helps reduce frizz, increase shine and protect against heat. Apply a few drops before blow-drying, curling or straightening to help protect the hair while leaving it smoother and shinier.
You can use Olaplex Bonding Oil both before and after straightening. Before straightening, it helps prep the hair by smoothing frizz and adding heat protection. After straightening, it works as a finishing oil to add shine, soften flyaways and give your hair a polished look.
Apply Olaplex Bonding Oil after blow-drying and before using your straightener. Use 1–3 drops through the mid-lengths and ends, then make sure your hair is fully dry before heat styling.
Once your hair has cooled, apply a tiny amount to the ends and surface layers of the hair to smooth flyaways and boost shine without making your style feel greasy or heavy.
Yes, Olaplex Bonding Oil can be suitable for fine hair because it has a lightweight feel. The key is to use a small amount and avoid the roots.
Start with 1 drop, apply it to the ends only, and add more only if needed. This can help add shine and softness without making fine hair look greasy or weighed down.
You can use Olaplex Bonding Oil daily, or whenever your hair needs extra smoothness, shine or heat protection. It works well on both damp and dry hair, whether you are styling, refreshing the ends or controlling frizz between washes.
Because it is an oil, it’s important not to overapply. Start with a small amount, usually 1 to 3 drops, and build gradually if needed. Using too much can leave the hair looking heavy or greasy.
Olaplex Bonding Oil does not directly make your hair grow. However, it can help hair look and feel healthier by reducing frizz, adding shine and helping to protect against styling damage.
When hair is better protected from breakage, it may appear fuller and healthier over time, but it should not be treated as a hair growth product.
Olaplex No.7 Bonding Oil is a multitasking styling oil that helps smooth frizz, boost shine, soften the hair and support heat protection. It is also designed to enhance colour vibrancy and leave hair looking healthier and more polished.
It can be used on wet or dry hair, before heat styling, after styling, or as part of your everyday haircare routine.
