But while it sounds like the perfect solution to damaged hair—and it’s definitely more effective than regular conditioner at protecting your locks from future damage—some people have wondered if they can just leave Olaplex in their hair overnight to get even better results.

The answer is yes… but not quite. Here’s why:

How long can I leave Olaplex 1 on my hair?

Olaplex 1 can be left on hair for up to 3 hours. It can also be left on hair for up to 24 hours, and up to 48 hours. You can leave Olaplex 1 on your hair for up to 72 hours.

How do you use Olaplex No. 1 and 2?

Olaplex No. 1 is a leave-in treatment that helps to restore and rebuild damaged hair, while Olaplex No. 2 is a rinse-out treatment for repairing breakage caused by color, bleach and heat styling tools.

When using both products together, apply Olaplex No. 1 first after shampooing your hair with water or an oil cleanser such as Briogeo Rosarco Milk Reparative Leave In Conditioning Spray ($23) or Aesop Resurrection Aromatique Hair Treatment Oil ($35). Then apply the rinse-out treatment before washing it out with cool water.

If you’re looking to repair your damaged locks at home without having to head into the salon (or if you’ve already gone through that process and want continued protection), try following this technique: Every other day (so as not overload on protein), apply ample amounts of both treatments onto towel dried strands; work them in by finger combing through them from root to tip; wrap each section up in plastic wrap; put an old t-shirt on top; let sit for 20 minutes before rinsing out with cool water

Can you mix Olaplex with conditioner?

Can you mix Olaplex with conditioner?

You might be tempted to use a regular deep conditioner after washing your hair, but it’s not necessary. We recommend using an Olaplex-approved product or leave-in treatment after washing your hair. The best thing to do is rinse the excess conditioner out of your hair and then apply the Olaplex treatment directly onto wet or dry hair (it doesn’t matter). Then let it sit for three minutes before washing out!

What does Olaplex do for your hair?

Olaplex is an ingredient you can use on your hair to help repair the broken bonds in your hair. It is also a product that helps to repair damaged hair.

When you use Olaplex, it will help to repair your damaged hair so it becomes healthy again. This is a very important step because if your hair is not healthy, it won’t be shiny and smooth like it should be!

Does Olaplex 3 work better overnight?

Yes, you can leave Olaplex 3 in your hair overnight.

That being said, it’s not necessary to do so.

The official recommendation from the website is that it’s best to leave the treatment in for one hour and then rinse out before washing your hair as usual with shampoo and conditioner. If you want to keep it in longer than that, there’s no reason why you wouldn’t be able to do so (as long as the bottle says four hours).

How long should I leave Olaplex 3 in my hair?

You can leave Olaplex 3 in your hair overnight. You’ll need to shampoo it out the next morning, but this is safe to do. It’s recommended that you don’t leave Olaplex 3 on for more than a few hours.

Is it too late to use olaplex?

No, it’s never too late! If you’re wondering how long you can leave Olaplex on your hair, the answer is always, “yes.”

  • Up to 24 hours after bleaching: You can use Olaplex up to twelve hours after bleaching. So if you go in for a root touchup and add some highlights or lowlights, Olaplex will work just fine on those strands of highlighted or lowlighted hair. And if you get that perfect shade of blonde and then decide to jumpstart your roots with some more color work? No problem either! Just add some new color at night and apply Olaplex before bedtime. Your hair will thank you in the morning (or whenever).
  • Up to 24 hours after coloring: As long as your stylist didn’t use bleach during their color process (which could cause an early reaction), adding Olaplex during this time won’t cause any issues at all. Your stylist will be happy because they know what they did works well together, and so will everyone else because their LOVELY COLOR won’t fade!
  • Up to 24 hours after heat styling: We love blowouts but hate them too…in a way…because we know they’ll ruin our favorite style soon enough—but not if we have olaplex on deck! This product will help prevent damage caused by curling irons/flat irons/hot rollers/etc., so even though heat styling might accelerate fading slightly due to increased friction between strands as compared with un-styled hair (which has little surface area contact), it’ll keep those damaged areas from actually breaking off entirely instead of just looking like straw when we flip our heads upside down without noticing how much damage has been done over time until reaching an inflection point where breakage occurs rapidly enough that no one knows what happened between now and yesterday when everything seemed fine I swear nobody touched my head but me no matter who says otherwise don’t

You can leave olaplex No. 1 on your hair overnight, but you will need to shampoo it out the next morning. It’s safe to leave it on for a few hours.

Olaplex No. 2 has an even higher concentration of cross-linkers than the first product and should only be left in for 20 minutes at a time, so this one is best used as a weekly treatment rather than something you use every night before bed.

The third formula—olaplex No. 3—is milder than its predecessors and has some moisturizing properties that make it another good option for frequent use between treatments with Olaplex One or Two (or both). However, if your hair is fine or thinning out significantly due to damage from coloring processes like bleaching or toning, we recommend using this product as little as possible because it doesn’t contain nearly as much crosslinking technology as either One or Two do (and therefore won’t prevent breakage nearly as well).


I hope that this article has given you a better idea of how long it will take to get your hair ready for styling. If you have any questions or concerns, please feel free to reach out! I’d be happy to help.
