Olaplex No.9 Bond Protector Nourishing Hair Serum

A lightweight leave-in hair serum designed to protect, nourish, and improve the overall health and appearance of the hair. Powered by Olaplex's patented bond-building technology, No.9 helps defend against daily damage while leaving hair feeling softer, smoother, and more manageable.

The weightless formula helps control frizz, enhance shine, and protect against heat styling, making it an easy addition to any haircare routine.

Suitable for all hair types, including coloured, blonde, chemically treated, and heat-styled hair.

Why I Recommend It

This is one of my favourite styling products because it's incredibly lightweight while still providing heat protection and nourishment.

I love No.9 because it helps protect the hair from daily styling without leaving it feeling heavy, sticky, or greasy. It smooths frizz, adds softness and shine, and helps make the hair more manageable while still maintaining natural movement.

I often recommend it to clients who use heat styling regularly but don't enjoy the feel of heavier creams, oils, or styling products.

It's particularly great for finer hair types that need heat protection and smoothing without sacrificing body and volume.

A little goes a long way, making one bottle last much longer than most people expect.

Best For

• All hair types

• Coloured or blonde hair

• Heat-styled hair

• Fine hair

• Frizzy or flyaway hair

• Anyone wanting lightweight heat protection, shine, and smoothness

How To Use

Apply a small amount to damp hair before styling, focusing on the mid-lengths and ends.

Can also be applied to dry hair to help smooth frizz and add shine.

For best results, use before heat styling and alongside your favourite Olaplex styling products.
