Olaplex No.7 vs Moroccanoil
Last reviewed
Quick answer
Buy Olaplex No.7 Bonding Oil when bleached, chemically treated, or heat-styled hair needs a few metered drops for shine and breakage, including before a hot tool. Olaplex states heat protection up to 450°F/232°C. Use 2–3 drops on damp or dry hair, not a palmful.
Buy Moroccanoil Treatment Original when medium-to-thick or curly hair wants a richer conditioning and detangling finish. Moroccanoil says a small amount on clean, towel-dried hair from mid-lengths to ends. This listing is the original 3.4 fl oz bottle. If hair is fine or very light, the verdict says look at Treatment Light instead.
You can use both. They are different steps, not two names for the same oil.


Moroccanoil
A richer argan oil for conditioning, detangling, and shine.

Comparison
| Olaplex No.7 Bonding Oil | Moroccanoil Treatment Original | |
|---|---|---|
| What it is | Bonding Oil. The verdict says two or three drops give shine, frizz control, and heat protection up to 450°F, without the slip of a heavier oil. This listing is 1 fl oz. | Moroccanoil Treatment Original. The brand calls it an argan-oil conditioning and finishing treatment that detangles, smooths frizz, and adds shine. This listing is the original, 3.4 fl oz, not Treatment Light. |
| When to use it | On damp or dry hair. Olaplex says you can use it before heat styling and again after styling for shine. | On clean, towel-dried hair before you dry, or a smaller amount on dry ends. |
| How to apply | Turn the bottle upside down and tap out a metered drop. Olaplex says to apply 2–3 drops and style. The verdict says never a palmful. | Moroccanoil says a small amount on clean, towel-dried hair from mid-lengths to ends, then blow-dry or air-dry. On dry hair, use it to tame flyaways and smooth ends. The verdict says a pump on towel-dried hair, or a drop on dry ends. |
| Hair it suits | Olaplex calls it a concentrated, weightless oil for every hair type, and says to match the amount to your texture. The catalog lists it for dull, heat-styled ends. The brand also says it is suitable for chemically treated hair and that it strengthens to reduce breakage. | The same product page says the original is for all hair types, then the FAQ splits it: original if hair is medium to thick or curly, Treatment Light if hair is fine or light-colored. The page calls the original the richer formula for medium-to-thick hair. The verdict matches that caution. |
| What it does not do | It is not a rich conditioning oil, and it does not replace a pre-shampoo treatment. Olaplex says it will not stain hair color. Fine hair still starts at 2–3 drops, not a coat. | It is not a bond-building oil and it is not No.7’s metered drop. This page does not link Treatment Light. Fine or very light hair is the reason to leave this original bottle. |
Who should pick which
Bleached or heat-styled hair
Hair is bleached, chemically treated, or heat-styled, and heavier oils weigh it down or do nothing against a hot tool. Buy No.7 for a few metered drops. Olaplex states heat protection up to 450°F/232°C.
Medium-to-thick hair
Hair still looks thirsty after conditioner, blow-dries drag, and the hair is medium to thick or curly. Buy the original for that richer conditioning and detangling finish. If hair is fine or very light, the verdict says look at Treatment Light instead of this listing.

Using them together
On clean, towel-dried hair, use a small amount of Moroccanoil Treatment Original from mid-lengths to ends if you want the conditioning and detangling finish. Then use 2–3 drops of No.7 on damp or dry hair, including before heat. That order is each product’s own direction. It is not a routine either brand publishes as a pair.
Keep both amounts small. Fine or very light hair is the caution on the original Treatment: the verdict points that hair at Treatment Light, which is not the bottle on this page.
Common questions
Who should pick Olaplex No.7, and who should pick Moroccanoil?
Pick Olaplex No.7 Bonding Oil when bleached, chemically treated, or heat-styled hair needs a few drops for shine and breakage. Olaplex says 2–3 metered drops on damp or dry hair, including before heat, and states heat protection up to 450°F/232°C. The catalog listing is the 1 fl oz bottle. Pick Moroccanoil Treatment Original when medium-to-thick or curly hair wants a richer conditioning and detangling finish. Moroccanoil’s FAQ says to use the original for that hair and Treatment Light for fine hair. This listing is the original, 3.4 fl oz.
Does Olaplex No.7 protect hair from heat?
Yes. Olaplex states that No.7 provides heat protection up to 450°F/232°C, and the directions include using it before heat styling. The labeled amount is still 2–3 drops. Moroccanoil’s Treatment Original directions say to apply a small amount and then blow-dry or air-dry. That page does not state a heat-protection temperature.
Is Moroccanoil Treatment Original a problem for fine hair?
It can be the wrong bottle. Moroccanoil’s FAQ says to use the original if hair is medium to thick or curly, and Treatment Light if hair is fine or light-colored. The page also describes the original as the richer formula for medium-to-thick hair. The Glow Ritual Finds verdict says the same thing: if hair is fine or very light, look at Treatment Light. This page links the original only. No.7 is the lighter oil in this pair. Olaplex calls it weightless and starts every hair type at 2–3 drops.
Can I use Olaplex No.7 and Moroccanoil Treatment together?
Yes, if you want both jobs. On clean, towel-dried hair, Moroccanoil says a small amount from mid-lengths to ends to detangle and condition, then dry. Olaplex says 2–3 drops of No.7 on damp or dry hair, including before heat. Using a small amount of the original and then those drops follows each brand’s own directions. Neither brand publishes a combined routine. If hair is fine or very light, skip this original Treatment and keep No.7 to a few drops.
How much of each oil should I use?
No.7: turn the bottle upside down and tap out a metered drop. Olaplex says 2–3 drops on damp or dry hair. The verdict says never a palmful. Moroccanoil Treatment Original: a small amount on clean, towel-dried hair from mid-lengths to ends, then blow-dry or air-dry. On dry hair, use less, on the ends. The verdict says a pump on towel-dried hair, or a drop on dry ends.
