Olaplex No. 7 Bonding Oil

Olaplex No. 7 Bonding Oil is the brand's most versatile product - a lightweight oil that delivers bond-building benefits alongside practical styling benefits. Unlike heavier oils, No. 7 is so lightweight that it can be used on fine hair without weighing it down. We tested this on fine, color-treated hair and found it exceptional. A single drop worked through damp hair before blow-drying added noticeable shine and reduced frizz without any heaviness. The bond-building technology provides cumulative benefits with regular use, gradually improving hair strength and elasticity. At current pricing for 1 oz, it's expensive per ounce, but the formula is extraordinarily concentrated - you truly only need 1-2 drops per use. The bottle lasts for months. For anyone already using Olaplex products, No. 7 is an essential addition to the routine.
