OLAPLEX N°.7 Bonding Hair Oil

Olaplex N°.7 is the finishing step people reach for once they've caught the bond-building bug. It's a tiny bottle that does a lot of quiet work: shine, smoothing and heat protection in a couple of drops.

Key features

• It's concentrated, so a couple of drops goes a long way and a bottle lasts
• Built-in heat protection means one fewer product before you blow-dry or flat-iron
• It targets frizz and flyaways, which is where most finishing oils earn their keep
• It's positioned for every hair type, so it's not just for thick or curly hair
• Pairs naturally with the rest of the Olaplex line if you already use N°.3

Best for

Anyone who heat-styles and wants shine and frizz control without a greasy finish, especially color-treated hair.

Things to consider

• It's easy to overdo; too much can weigh fine hair down
• It's a small bottle at a premium level for an oil
• If your hair is healthy and frizz-free, a basic oil may be all you need

Verdict

An easy recommendation as a finishing oil with heat protection built in. Use it sparingly and it earns its spot.
