If you are looking for a Frizz Control that lasts the whole day, buy it! The Olaplex N°.6 Bond Smoother leave-in styling cream is claimed by the listing to provide 72-hour frizz control as well as heat protection of up to 450ºF/232ºC.
The downside: It’s a styling product, not a repair treatment—it won’t be a replacement for your shampoo or conditioner. Ideal for hair that has a tendency to frizz over and is frequently blow dried or air dried.
It’s great for: regular blow-dryers and air-dryers with frizz problems.
Not for: people who are looking for a deep repair mask or a wash day replacement.

Pros:
- The 72-hour frizz control, along with humidity resistance, is listed.
- Hazard rating up to 450ºF/232ºC.
- 91% easier reporting with a list.
- Reported 71% fewer breakages when styled and brushed.
- Coconut based emollient, vitamin E and sunflower seed oil.
Cons:
- Styling cream only — that is, on top of your regular wash.
What Decides It For Frizzed Hair?
There are three things that make a leave-in hair cream useful—how long it lasts, whether it can hold heat and what it actually contains. Each of these is summarized by the listing below.
Frizz control didn’t just last one afternoon, it lasted more than 72 hours
This is its “clinically proven 72 Hr frizz control + humidity resistance” description. That’s the headline number and that is important if your day is long — a commute, a lunch break outside, an evening out. A few hours is the time that you will be stuck with the frizz or redoing your hair.
You wash at morning and don’t use your hair throughout the day until you wash them at night that period is covered. Works well for those who have a steady day; not as effective for those who are getting wet a lot.

Most styling tools can be heated to a maximum temperature of 450ºF/232ºC
The listed rates are for 450ºF/232ºC heat protection. This is the maximum setting the manufacturer specifies and this is the figure you should compare to the setting of your tool. If you blow dry then flat iron, this is the number that determines if one product will do both, or if you need another product under it.
All it offers you is a dryer or straightener heat setting that you can compare to the one you purchase.
Conditioning agents and oils do the smoothing job
The ingredients include the usual cell softening and anti-static components (cationic conditioning agents) as well as a combination of coconut-based emollient with vitamin E and sunflower seed oil to add a “subtle shine. As a surface smoothing formula, it works on the outside of the hair, and the feel of the cuticle, but not the bonds within the hair.
So the term “Bond” is not referring to a repair claim here, but it is referring to the listed benefits: Frizz control, Definition, Softening and hydration. If you want to rebuild your bond, it’s a different step on the range. This layer is the last one.
The price may vary from one online retailer to another.
What’s In The Box, And What Isn’t
The listing refers to the single product of a leave-in styling cream in a tube of 100 mL. That’s it. No applicator, no comb, no travel size, no companion product in the box — the listing lists the cream and its size only, no other products are mentioned as included.
This means that your routine remains your routine. You will still need to use your shampoo, conditioner and any bond or repair product you are already using on your hair, as it is applied after that. Consider it the step between wash and style.
Is that enough to make up the answer? Yes – a cream applied to damp hair before being dried or left up will kill frizz, smooth and protect the hair from heat in one package for the styling application. When someone is purchasing a system, they are purchasing the final piece of a system. If the frizz and heat rating are the same as how you wear your hair, then it is worth it!

Frequently Asked Questions
Will this work on thin hair without adding weight?
It claims to be a smoothing cream for fine hair, as listed it doesn’t weigh down, which is what the manufacturer says. Do not overestimate, and if you need to know the quantity, refer to the listing’s directions before purchase.
Do I need to wash it out or reapply it?
It is a leave-in cream which means it’s not rinsed off after applying, it stays in until the next wash. Reapplication will be dependent on the type of hair as well as how long between washes, and the frizz-control claim listed in the listing is a statement of how long the hold is indicated to last, rather than a schedule for reapplication. Apply it to wet hair prior to styling.
Should you buy a leave-in styling cream at all?
It’s if frizz and heat styling are a part of your week, as the listing claims it offers frizz control, smoothing and heat protection in one application. Avoid using it if you air-dry your hair without heat or experience little frizz.
Should You Buy It?
If frizz is the primary issue and you frequently blow-dry or air-dry your hair: yes. The listed 72-hour frizz control is the smell of the humidity resistance, as well as the heat protection up to 450ºF/232ºC, are all directed to the same buyer — someone who does his or her own hair styling at home and wants one cream to smooth and protect from heat in one go.
The detangling and breakage numbers the listing lists indicate that it is worthy of making its place in that routine.
For repair: no. The listed benefits are styling and smoothing, not bond rebuilding, so this will not rebuild bonds. Search for a binder repair treatment and have a cream such as this as the last treatment applied.
