Olaplex No.5 Leave-In Moisturize & Mend Leave-In Conditioner

A lightweight leave-in treatment designed to provide lasting hydration, smoothness, and protection without weighing the hair down. Powered by Olaplex's patented bond-building technology, No.5 Leave-In helps moisturise, strengthen, and reduce the appearance of damage while leaving hair softer, healthier, and more manageable.

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

Why I Recommend It

This is a fantastic option for anyone whose hair feels dry, frizzy, tangled, or difficult to manage.

I love it because it provides ongoing hydration and protection throughout the day without leaving the hair feeling heavy or greasy. It's one of those products that works quietly in the background, helping the hair feel softer, smoother, and easier to style.

I often recommend it to clients who struggle with dry ends, frizz, or hair that feels rough between salon visits.

It's also a great option for people with very fine hair who find traditional conditioners too heavy. In some cases, I recommend skipping conditioner altogether and using No.5 Leave-In instead. It provides lightweight moisture and manageability without weighing the hair down, helping fine hair maintain body and movement while still getting the care it needs.

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