Head to Head
Olaplex No.7 Bonding Oil vs Moroccanoil Treatment
Olaplex No.7 and Moroccanoil Treatment compared on bonding versus argan conditioning, weight, heat protection and which hair each one truly suits.


Olaplex No.7 Bonding Oil
A concentrated bonding oil dosed in drops, with published heat protection.

Moroccanoil Treatment Hair Oil
The original argan treatment, still the benchmark for thick hair.
Where They Differ
Bonding active versus argan conditioning
No.7 leads its ingredient list with Bis-Aminopropyl Diglycol Dimaleate, the brand's patented bond building active, supported by sunflower and pomegranate seed oils. Moroccanoil leads with argan kernel oil and linseed extract in a silicone base, a formula designed to condition, detangle and smooth the surface. One is organised around internal structure, the other around surface condition, and they feel accordingly different in the hair.
Weight, dose and bottle size
The physical contrast is stark: No.7 is 1 fl oz dosed in drops, Moroccanoil is 3.4 fl oz dispensed by the pump. Fine hair that collapses under product will live happily with the Olaplex and must ration the Moroccanoil carefully, while coarse, dense hair often finds No.7 too light to finish alone and takes to the Moroccanoil's weight immediately. Size for size, the Moroccanoil is also the longer lasting bottle in a daily routine.
Heat protection and scent
Olaplex publishes heat protection up to 450 degrees Fahrenheit for No.7; Moroccanoil claims thermal damage protection in its listing title without publishing a temperature. On fragrance, Moroccanoil's Fragrance Originale is a famous, assertive signature scent, while No.7 wears comparatively quietly. Heat stylers who want the figure in writing land on Olaplex; buyers who shop by scent and richness land on Moroccanoil.

Questions, Answered
Can I use both together?
Yes, and coarse haired owners of No.7 often do exactly this: a drop or two of No.7 for its bonding and heat layer, with Moroccanoil over the ends for conditioning weight and finish. Apply the lighter oil first on damp hair and the richer one second, keeping the total dose modest.
